Inline Tube Car Talk - Questions & Answers
What can I expect when I order a brake line set?
Inline Tube lines come completely preformed identical to the factory
originals. Our lines are made using our state-of-the-art CNC computer benders
and scanning equipment. Whether you buy stainless steel or tin coated steel
lines, they will have factory correct fittings, spring wrap and cloth wrap in
the original locations. We are guys working on cars too and we know you
want: the highest quality parts available, manufactured specifically for your
car, at a fair price, delivered a few days later.
What is a shipping bend?
bends are required to ship all lines over 6 feet in length. This bend is a
large-radius bend that is the same as a 5 gallon bucket. The tubing is not
stressed so the bend is easily straightened to the original form. To remove
the shipping bend, simply unroll the section marked between the tags on a flat
surface such as a table or garage floor. Use the floor as a straight edge.
Whatever gentle bend is left, straighten by hand. When the tube is straight
you are done.
Is stainless steel harder to seat than OEM steel?
materials seat the same. The tubing is not what causes the line not to seat.
Most of the time you are reusing a master or wheel cylinder and the seat in
the used component has a seat ring from the old line. When reusing old
components with new lines, either stainless or OEM steel, they must form a
seat in the component. To form a good seat, loosen the line slightly and
retighten several times. This allows the two materials to re-form together and
create a strong seat.
How long will it take for my order to ship and what will be the shipping cost?
After your order is placed, our sales
professionals double check and process the order. It will be filled and
proceed to the shipping department within 24-48 hours, where Federal Express
will deliver it to your door step in a matter of days. Tracking numbers are
available within 48 hours. Because of our capacity, your lines could even go
out the same day on orders for more popular vehicles. Shipping cost is
determined by the size of the box, the weight of the materials and the
distance being shipped. Click on the delivery truck icon to figure your
Should I use teflon tape on my new lines?
use teflon tape to seal lines. Teflon seals the threads to the component but
does not stop the leak. Remember, the cone of the component and the flare of
the tube is what seal the connection. The tube nut only holds the flare to the
seat. Teflon tape is only used on pipe threads (tapered fittings), not brake
Should I buy stainless steel or OEM steel lines?
stainless and OEM steel perform exactly the same for braking. The difference
is the material. Both lines have the fittings on the ends, cloth wrap and
spring wrap identical to the factory originals and are very hard to tell
apart. The OEM steel lines are a tin coated steel line identical to the
original and will last as long as the original. The stainless steel lines will
never rust tarnish or corrode.
Do brake and fuel lines include hold down clips?
down clips and brake hoses are not included with brake tubing sets. However,
we have compiled a large list of clip sets available for most cars and trucks.
If we do not have an exact set for your application, you can purchase a
general OE style clip set for each size line or match up your original clips
from over 50 different styles listed under the clip section online or in our
catalog. We also carry hundreds of brake hoses in both OEM rubber and braided
What brake fluid should I use in the system?
3 originally came in the brake system. This fluid can destroy your paint and
collects moisture which reduces performance over time. Under extreme braking
conditions, such as constant drag racing or excessive braking, DOT 3 will out
perform DOT 5 (silicone fluid). DOT 5 is an excellent choice for museum and
show cars, since it will not collect moisture and does not harm paint. Never
mix DOT 5 and DOT 3 Fluids.
Can I double flare stainless steel tube by hand?
you can double flare stainless steel lines bought from Inline Tube. Our tube
is fully annealed and is very easy to work with. We recommend and offer
several good flaring tools: Rigid, Imperial Eastman or Blue Point. Carefully
follow all the instructions that come with the tool and the tubing, and the
flare will be perfect every time.
Why should I buy from Inline Tube over other companies?
At Inline Tube, we earn you as a customer. We have been hunting original
parts off of original cars in junk yards all over the country for the last 10
years, to build the largest pattern library in the country. The other guys are
still waiting for you to send it in. Other companies bend by hand or have old
CNC benders. Inline Tube has 6 state-of-the-art triple head, 2000 and
newer benders that are directly linked to our exclusive laser scanner. We are
also the only company that has CNC equipment for manufacturing all of our
cable parts and tube nuts. So whether the fittings are color coated or
stainless, they will be exact to the originals. We never substitute generic
fittings. We constantly offer new products for complete and accurate
exclusive stainless steel and OEM parking brake cables are a spiral match to
the originals in every detail and specification. Other companies sell black
plastic-coated cables that were never offered from the factory. Inline Tube
provides specific brake and fuel line clip sets for hundreds of vehicles while
others offer a handful of generic clips. We will continue to raise the bar
with our latest products, new cable hardware, concourse detail tags, brake
valves, tees and blocks, and other parts you need and request. Inline Tube has
been dedicated to the classic car hobby for over 20 years, building and
showing cars, talking with customers, and listening to what you want in a
tubing company: the highest quality parts at the best price.
What is a 45 degree versus a 37 degree flare?
factory produced automobiles use the industry standard, which is a 45 deg.
double flare using one flare fitting. The double flare is stronger and needs
no support sleeve. 37 deg or AN, which stands for Army/Navy standard, is used
on military equipment and for non-automotive uses. When using AN on automotive
components (masters, wheel cylinders), each AN fitting must be used with an
adapter, a sleeve and a nut with a single flare.
What are CNC tube benders versus manual tube benders?
tube benders are Computer Number Controlled machines that use numerical
coordinates to make exact parts. These state-of-the-art machines produce the
finest parts on the market. Every Inline Tube part made for your car is an
exact reproduction of the original and our computerized process ensures that
you are getting the same quality part every time. Inline Tube has 6 new CNC
benders to keep high quality orders shipping daily.
machines use a series of levers that are subject to human error. These levers
must be pulled the same every time, with the same pressure every time, in
order to produce a part. For some companies, this method of reproduction is
close enough. Here at Inline Tube, the parts are our reputation and we will
not settle for “almost” quality.
Will my new lines come with the correct fittings, cloth wrap and spring on them?
all Inline Tubes come completely computer preformed, with the fittings on the
ends, spring wrap and cloth wrap matching the original lines. All you have to
do is unbolt the old and insert the new. Original tin coated steel lines
feature color coated fittings and tin coated spring wrap identical to the
originals. Stainless steel lines also feature popular color coated fittings
and stainless steel spring wrap. Stainless fittings are available at a slight
up charge. Only Inline Tube makes every fitting type in stainless; we do not
substitute generic stainless fittings on any tube. All line fitting ends are
capped, guaranteeing correct fitting direction, protection and clean lines
How can you help me if my car is not listed in your
catalog or web site?
we have a physical library of over 14,000 parts, we can reproduce any line in
OEM or stainless steel working from your original. If we do not have your
application, we can make it custom for you. When we receive your original, we
will call you with a quote. Once the quote is accepted, the new part(s) will
ship within a few days. Prices for custom duplication are based off similar
lines in our catalog with a slight up charge.
Do you have lines for me if I have converted my car to a dual master
cylinder and disc brakes?
Inline Tube, we make a variety of dual master disc brake conversions line sets
for many popular cars and trucks. Line sets usually require our proportional
valve and bracket in the system and then the lines are ready to bolt in for
your conversion. Check this site or our catalog for the sets we offer.
Do I need a proportioning valve if I have converted to a dual master but
have kept the drum brakes?
converting to a dual master, no proportional valve is needed if the car is
kept with all drum brakes. The system is simply separated to have
independent front and back systems, so if one line should fail, the other half
of the braking system will not be affected. You will need a distribution block
that connects the second master cylinder line.
My car has a single master cylinder. Should I switch to a dual master?
you are keeping the four wheel drum system, you do not need to convert to a
dual master. The concern is that if you lose one line, all braking will go.
The solution is stainless steel lines. They will never rust or deteriorate.
When converting to a dual master, you will need a new master cylinder, a
distribution block that will accept the second master cylinder line and new
clips to hold the additional lines in place. When you are all done, you may
affect the performance of the brakes with mismatched components, resulting in
a stronger or weaker brake pedal. Brake safely with new lines from Inline
Do I need a dual master and proportioning valve if my car has been
converted to disc brakes?
Disc and drum brakes require different pressures. Disc brakes require about
1000 lbs. of pressure and drum brakes use about 300 lbs. This is why the dual
master requires a proportioning valve to control the pressure in the system.
Whether the car is disc front or all wheel disc, a proportioning valve is
I am building a street rod and I am looking for a line set. Can you help?
Tube makes preformed brake, fuel and transmission lines for production cars
and trucks. While many disc brake conversion line sets are available, we do
not have patterns for every combination. If the car has been modified, such as
relocation of the master cylinder, proportioning valve or a custom rear axle,
we suggest one of our straight line sets. For a complete custom car or street
rod, we offer several straight line kits. These sets come with tubing,
fittings, spring wrap, blocks, and clips to hold it all in place. We also can
provide you with high quality tubing tools to make custom installation an
What size tube should I used for a custom job?
the smaller the tube, the more pressure it creates and the better the brake
system will function. Disc brakes require about 1000 lbs. of pressure and the
drums use about 300 lbs. Disc brake cars use 3/16” tubing and drum brake
cars use ¼” tubing. If you are building a street rod that has front discs,
the entire system is typically plumbed in 3/16” tube. All straight length
tubing is available in 6' straight sections or up to 20' coiled.
What information is important to have to order from Inline Tube?
year, make and model of the vehicle are basic essentials. Other variables
include body type (hardtop or convertible, standard or extended cab, long or
short bed), wheelbase, engine, transmission, drum or disc, power or manual
brakes, manual or automatic (and type of automatic) transmission, suspension
rating (1/2, 3/4, 1 ton). Any changes that you or a previous owner has made to
the braking system and drive train are necessary to getting the correct
product. Inform us on whether the vehicle is factory disc or disc conversion
and the manufacturer of the kit.
