uxcell Pneumatic Air Tubing, 6mm OD x 4mm ID 9m(29.5Ft) PU Polyurethane Air Compressor Tubing Hose Pipe Blue

It is functional.

I'm not sure what to say about this product. I purchased it for a use which it was never intended for I'm sure. I needed vent line (unpressurized) for a pair of ARB differential air locker solenoids installed in an off road 4WD vehicle. I coupled this with "SMC KQ Series Brass Push-to-Connect Tube Fitting, Universal Elbow, 6mm Tube OD x M5x0.8 BSPT Male, Black" which screw right into the air outlets of the solenoids. I wasn't sure what to expect but I couldn't find anything else that might do what I wanted. The solenoids are installed in the engine bay so there's considerable heat to deal with. Fumes and gear lube from the differentials is sometimes exhausted through the fittings and tube so they're exposed to more than just clean air. After four months (one summer's heat) or so both products are holding up fine. The only down side is that I only needed about 8'. Guess I need to get a couple more vehicles. :)

Good kit, worth what I paid. Will have to see how air line and connectors holds up in the Texas heat

I use this material for my laser burner for air assist. PLENTY of tubing for my needs. very durable. Thank you.

I needed this for the puffer on my scroll saw. It had to be a very specific diameter, and this was it. It is nice and flexible. Perfect for my need.

Good tubing great price

Good tubing. More firm than silicone tubing so won't kink as easily on turns. May need to heat up slightly to allow it to fit on air stones

Doesn't handle hot weather under any type of pressure

Product OD is 6mm, as specified.
