Abstract: A fluid connector assembly having a flexible austenitic annealed stainless steel 300 series corrugated convoluted tube. At least one end of the tube has a smooth end which is free of convoluted corrugations. The corrugated portion has a hardness range of 150 to 190 points Vickers and the smooth end of the tube has a range of hardness of 275 to 380 points Vickers. A metal compression nut is used in combination with a metal compression ring in a metal fitting the smooth end to couple. The metal fitting is capable of coupling the fluid connector to another connector.

Abstract: A polyethylene plastic valve has a molded cylindrical body portion with an internal chamber with inlet and outlet openings. A unitary plastic plug member is rotatably positioned in the chamber. The plug member has an actuator portion formed of impact resistant plastic material, and a plug portion formed of dimensionally rigid plastic material with a flow passage therethrough. The plug member has open and closed positions. Dual durometer valve seats are positioned on the plug member to close the inlet and outlet openings in the valve body. The actuator portion of the plug member extends upwardly through the chamber and seals the internal chamber at the top by means of a circumferentially extending flange portion. A bottom cover plate is fused to and seals the lower end of the internal chamber. The bottom cover is arranged to disengage from the valve body and relieve excess pressure build up in the lower end of the chamber.
