One-way valve for the Connect tubing system. The Quick Connect plumbing system is suitable for hot / cold water and heating installations on board. It represents a particularly reliable solution that has been specially developed for mobile applications. It can withstand water temperatures of up to 65°C. Can be used without limitations in drinking water systems. The semi-rigid pipes can be laid flexibly. Pipe installation should be fixed with a clip approximately every 50 cm, fittings and valves should not be held or supported by the pipe. Pipe outer Ø: 15 mm. The connectors can be fitted and removed as often as required without special tools. Thanks to pre-set cutting marks, the pipes can be cut to length quickly and easily: cut the pipe at one cutting mark with pipe cutters and push into the connector up to the next cutting mark - this ensures that the connection is watertight.
