Beduan 6mm x 4mm Black Pneumatic Tubing Pipe PU Polyurethane Air Compressor Tubing Hose Pipe Line Fluid Transfer 39.4ft 12 Meter

I used this tubing to fix a leak on my 60 watt CO2 laser, did I need the whole role?, no but that's how it comes. It's flexible and durable and worked great for my repair of the Laser.

Great stuff, pretty stiff though if you're expecting it to be very flexible. To get good bends and around obstacles, fittings will work best.

Correct size, fits well.

Needed this tube for my CNC Spindle cooling. its working great so far

The 8mm flexible air hose on my California Air Tools air compressor CAT-4610 developed a crack and started leaking air. This is the hard black plastic hose. I bought this hose because of the low price and replaced the cracked hose. Took 15 minutes and my compressor was up and running. This hose has a sligthly smaller outside diameter but the inside diameter was a perfect fit. Just re-use the existing compression nut; install it on the new hose and tighten. Only problem is that I only needed 12 inches so I have a lot leftover.
