Duotight - 8mm Inline Check Valve

8mm Inline Check Valve is used to prevent liquid or gas flow in one direction, i.e. back into the regulator.

This fitting makes setting up and taking apart your system faster and easier than using barb and clamps.

Push the hose into the fitting when you attach it, and hold and push down on the collar to pull the hose out again when you want to take it apart. Compatible with both the 5mm x 8mm line and 4mm x 8mm line.
