The 1/4 inch Polyethylene RO Tubing White is designed for use with all 1/4 inch Quick Connect Fittings and offers excellent pressure and temperature ratings. The tubing is BPA-Free, is NSF Standard 58 Certified and has outstanding resistance to environmental stress cracking.  Suitable for all RO systems and water filters.
The Quick Connect Auto Shut Off Valve is used with float valves or pressurised tanks to shut off the supply line to an RO system. It utilises the back pressure created by the float valve or pressurised tank to shut off the water supply to the membrane. The Auto Shut Off Valve saves thousands of litres of water per year, without it waste water would continue to run out after the float valve is activated or the tank becomes full.
