alan0043 Posted March 21, 2017 Report Share Posted March 21, 2017 Hi Everyone, Can polyurethane tubing be used for air lines on the truck ? The tubing is more flexible and is easier to route. But is it save to use ? Is it DOT approved ? Any thoughts out there ?

Darryl&Rita Posted March 21, 2017 Report Share Posted March 21, 2017 I didn't realize plastic tubing was so difficult to work with. Use what's already there, Nylon. I have been wrong before, I'll probably be wrong again. 2000 Kenworth T 2000 w/N-14 and 10 speed Gen1 Autoshift, deck built by Star Fabrication 2006 smart fourtwo cdi cabriolet 2007 32.5' Fleetwood QuantumPlease e-mail us here.

MsChrissi Posted March 21, 2017 Report Share Posted March 21, 2017 While we are remotely on the subject; how do you track down leaks besides the obvious listening and soap bubbles, is there another method that works for slow leaks? Link to comment Share on other sites More sharing options...

Alie&Jim's Carrilite Posted March 22, 2017 Report Share Posted March 22, 2017 I used a system similar to an Infiicon to find vacuum leaks for resin infusion/vacuum bagging epoxies. I wish I had kept it for all the little truck leaks. Al- Stay with the nylon DOT rated tubing. The polyurethane tubing probably isn't pressure rated for the truck system working pressure. Do you have a link to what you want to use? Alie & Jim + 8 paws 2017 DRV Memphis BART- 1998 Volvo 610 Lil'ole 6cyl Cummins Link to comment Share on other sites More sharing options...

beyerjf Posted March 22, 2017 Report Share Posted March 22, 2017 back to the original question. Under NO circumstances would I use any item on any brake system not approved by the OEM, or sourced from a reputable aftermarket supplier. The material used in the brake lines is critical, in terms of it's construction, size and other engineering qualities. Once upon a time brake systems used copper tubing seemingly a pretty stout product. But was discovered that the vibrations of a mobile application caused cracking and all kinds of failures. The thickness of the wall of the brakeline is designed to mate perfectly with the fittings used in the same system, and is made of nylon, or a combination of braid and nylon depending on the application.

alan0043 Posted March 22, 2017 Author Report Share Posted March 22, 2017 Hi Everyone, Thank you for the answers. I will stick with the DOT tubing. One more question. How does someone get the curl out of the tubing ? I understand that there will always be some type of curl to the tubing. But when you open up a bag of tubing the tubing wants to stay the size of the package. I need to run the tubing from the cab about 25' to get to my hitch. Is there an easier way to get this tight curl out ?

Darryl&Rita Posted March 22, 2017 Report Share Posted March 22, 2017 Put a broom handle through the centre of the loop. Place the broom onto an opened step-ladder, one end on a rung, the other end on a spreader bar on the back side. Pull the end from between the "A-frame" of the legs. Allow the roll to rotate on the broom handle. It won't take all the twist out, but it will allow a clean pull, followed by lots of Ty-Wraps to hold it in position. I have been wrong before, I'll probably be wrong again. 2000 Kenworth T 2000 w/N-14 and 10 speed Gen1 Autoshift, deck built by Star Fabrication 2006 smart fourtwo cdi cabriolet 2007 32.5' Fleetwood QuantumPlease e-mail us here.

MsChrissi Posted April 14, 2017 Report Share Posted April 14, 2017 Inficon Whisper.... OMG this thing should have been called the Leak Whisperer. It paid for itself in it's first use, found three significant leaks very quickly, one just needed a tighten up the other two we replaced the fittings. It also gives you a sense of security knowing where the leaks are not. It can read you gently rubbing dry fingertips at an arm's length in a noisy room. Great on aircraft engines for determining cylinder leak down test cause, sniff in the carb, sniff in the exhaust pipe or sniff in the oil fill will tell you if you are leaking from respective valves or the rings.

Pete Kildow Posted April 14, 2017 Report Share Posted April 14, 2017 Wish one of our old Hard of hearing Mechanics would have had that tool. I told him the dash had a big air leak in it. Got back in the truck next day. Note showed he fixed the leak... Started the truck up and valve was still leaking. He tightened up a fitting that was not leaking. It was sure nice when he retired the next month. Pete Link to comment Share on other sites More sharing options...

Jemstone Posted April 24, 2017 Report Share Posted April 24, 2017 The Bose noise cancelling headphones are a perfect match for the leak detector. However, leak detection does not require that expensive of an headphone. Living in a small space, like a 5th wheel, does benefit from noise cancelling earphones. My wife can sit near me watching a TV show while I watch Hulu programs on my iPad. Using the noise cancelling Bose headphones, I hear litttle of her programs. I can also use the noise cancelling feature alone and read while she watches the documentary "Extra Loud Explosions of World War II."
