HONGLUSilicone Tube 6mm ID X 8mm OD Flexible Silicone Rubber Tubing High Temp Food Grade Tube, Flexible Hose Pipe for Pump Transfer, Homebrew

I use this cut into 4 equal lengths to power bleed my brake calipers h3en refreshing the fluid. Fits well over the bleeder screws and the fluid and air is visible.

Was three feet short on one of rolls witch caused haveto add splice and extra work otherwise tube seems fine

It's very difficult to determine how soft the tubing is going to be. For a peristaltic pump this is a little too hard, and water leaks through pump.

I am not overly impressed with this item because its so flexible that it kinks up with use and I end up juggling the tubing to keep it straight. This isn't a defect or anything like that, I just need a firmer tubing. For my personal needs its not practical. It is long enough and quite easy to cut into the needed lengths. My neighbor needs one this flexible in her greenhouse so I am gifting it to her. She's ecstatic!

This tubing is translucent so you can see most fluids as they flow through it but the tubing walls are far too thin for any significant pressure or vacuum application. It is even softer than latex tubing. I wouldn’t even recommend it for automotive vacuum line applications. I haven’t exposed it to high temperatures but, if it is made of good quality silicon, it should be fine up to about 400-500 degrees F.
