HPS HTSVH35-BLKx10 Black 10' Length High Temperature Silicone Vacuum Tubing Hose (60 psi Maxium Pressure, 3.5mm ID)

This stuff is the best 3.5 millimeter vac hose I've ever used. The junk available locally is either cheap rubber with kink-prone walls, or is not available in 3.5mm (still don't know why most of the country is driving around in cars with metric parts and the local stores mainly carry Imperial measurement parts) or is silicone with soft, thin walls that kink like crazy. This stuff is good stiff-walled silicone vacuum hose. I used this stuff to re-do the vac lines in my FD RX-7 and if you know how many vacuum hoses there are on those cars and how fun it is to replace them all, you only want to do that once, with something you can rely on. This is the stuff.

So this looks and feels like really good tubing. It is flexible, very thick walled, and sturdy. Should hold up to any amount of boost I throw at them.Downside is the inside diameter is really small. Because of this it is nearly useless on most of the things I needed it for. Thankfully it is durable and flexible and I was able to force it on some 1/4 barbs.The ID is small enough I’m concerned my wastegate and boost controller may not work properly.All in all it is a great product.. the ID of the tube just wasn’t ideal for my particular application.

I used this to replace my secondary air hose vacuum line on my 2004 BMW 325xi. It fit perfectly to the air pump, check valve, vacuum switch, and manifold. The material is very durable.

I used this to replace the vacuum lines on my N54 335i. Worked perfectly. High quality, pliable hose.

Used all 10ft and it works great. These were for pressurized lines ans they never bulged. Even next to high temperatures making the rubber more plyable. Did a full over haul of vacuum lines when boosting my car.

Great quality hose, slightly thicker than stock rubber hoses hence requires a little effort to fit back into the stock clips/holders. The inner diameter fits all stock fittings tightly. No leaks, no engine code, all good.

Best vacuum tubing out there. This is heat resistant, will not collapse and extremely stout. It will stretch over larger diameter pipes and not tear like rubber tubing.

Very similar to the current (non-fabric covered) vacuum hoses used on Audi / VWs. And superior to how the older fabric covered hoses tend to get brittle, crack off, and you have to go on the "where's the leak this time" hunts. Plus black doesn't raise the suspicions of the "smog" technicians.

Using these to replace all vacuum lines for my BMW N54. High quality replacement over brittle dried out stock lines. Still have to tackle the turbo wastegate lines but so far so good.

Good quality hose, nice and thick. Took just under 3 weeks to get to Canada, but was worth the wait. Measured it at almost 11 feet so an extra feet, big plus. Have yet to put it on the car but I have a good feeling it will exceed expectations.

Used on my 09 BMW 335 with N54 engine to replace worn/degraded vacuum hoses. Fit perfectly over factory vacuum host connect/nipple.

Flexible and thick. No imperfections, works as described. Withstands a good amount of heat vs your run of the mil vacuum line.

Center hole is not centered and part of the hose was cracked on arrival. Could just be a bad batch
