BEST Fittings BF One Way Valve Quick Coupler Compressor Connector Male-Female

BEST Fittings One Way / Non Return Valve Quick Coupler Compressor Connector Decanting / Compressor Connector with One-Way Valve. Male-Female Quick Couplers for connecting inline. Using this fitting inline on your small electric 300BAR compressor filling hose will allow you to open the cylinder valve straight away without having to build line pressure first. It works by preventing the air pressure in the cylinder from back pressurising through filling your line into the compressor and causing problems. Once the compressor pressure reaches that of the cylinder, the valve automatically opens and will allow the cylinder to be fully filled. Once filling is complete, bleed both sides of the fitting before disconnecting. High Quality Fittings, made in the UK. MAX WP 300 BAR, 4500psi
