The WEH® TW920 Quick connector for filling refrigerants overcomes the need to remove the cylinder valve cartridge when filling thus facilitating cylinder connection and filling. When applying pressure, the piston of the WEH® Connector moves forward and pulls out the pin of the residual pressure valve. Then filling procedure can start.
