Beduan 4 mm OD Pneumatic Air Line Tubing Nylon Air Hose for Fluid Transfer or Air Brake System 32.8ft (Black)

Order this to replace my car’s vacuum line. Works well. It is really hard and need to heat a little bit.

I had to install this tubing underneath my van, up to the engine compartment, in December. The tubing was very stiff in 50F weather, so I put it in a warm oven to relax it some. That worked, except it got cold and stiff again very quickly. It will kink if you force it straight, so you need to be gentle with it. I would have used the polyurethane version of this tubing so it would be easier to work with, but it would not have arrived in time. Other than that, it is sized perfectly for 10mm push to fit connectors, and does not leak.

I needed this exact size tubing and didn't want to search everywhere locally to find it. Great price and what I was looking for. Came tightly wrapped and very stiff. Lowest setting in my oven and it straighten out perfectly.

Great value but product has not of memory making it more difficult to work with.

I use this to bypass my main airbag pump so I can manually pump up the airbag systems. It works perfect. I've tried other tubes and I realize that most people sell 6 mm tubing and it's really quarter inch but there is a difference when it comes to the fittings. This is truly 6 mm and it works on all of the euro air systems. And it's definitely high heat. My issue I was having with other tubing was if I was sitting in standstill traffic the exhaust system would heat up the tube and pop it with this tubing . I have not had an issue at all in three months.

It fixed my California Air Tools 4.6 dual tank air compressor problem on the little piece that goes behind manifold. Known problem with this compressor. Just got it and put it on today, so will update if it changes or develops a leak. Cut the piece with razor knife easily. Pushed on tighter than expected, used pliers to push on, and pull off. Had to cut an 1/8 inch more off. Ran compressor till it shut off, aired up a couple tires a few pounds.Then undid my hose, and drained tank. Then ran again till it got to the cutoff pressure. No leaks, while I put away tools. Seems fine, I liked the high pressure ratings of this line.Drained tank. Will get a good workout with air chisel on driveway spot. Will update if fails. Have 32 feet left. Didn’t even take out of package.

Good fit to replace crumbling hoses under hood. The original black vaccum is a tad smaller diameter but the white and red originals seem to be same as the new vinyl. Use wd40 to soften rubber and a small jewel screwdriver wedged between tube and rubber fitting working along diameter carefully to break seal and old tubing will come right out.

The actual OD of the tube is spot on but this stuff is the biggest PITA to work with. Awful memory, wants to stay curled up and bent. Take a heat gun on low to it and it will help you manipulate it but it will link of you try to straighten it out too much at once. Ask me how I know
