摘要： Each gripper washer 22 is disposed between a gasket retaining ring 18 and an end connector 14. The gripper washers 22 can be any size and dimension, and made from any material, including but not limited to plastic, polyvinyl chloride, or metal. The gripper washers 22 are a washer-like structure, typically a metallic structure that comprises an interior diameter, a concentric inner periphery and an exterior periphery 24. Each gripper washer 22 is disposed between a gasket retaining ring 18 and an end connector 14, such that the exterior periphery 24 of the gripper washer 22 is in contact with, or in close proximity to, the shoulder 20 of the gasket retaining ring 18.

摘要： A grip lock connector member which connects a supply pipe from a source of water to a fire sprinkler through an interior grip lock connector. The grip lock connector includes a multiplicity of gripper teeth which form a tight grip connection to the supply pipe. The supply pipe is retained within an interior chamber and grasped and retained by the multiplicity of gripper teeth at the interior end of the interior chamber. A gasket or O-ring directly behind the gripper teeth facilitates a leakproof connection. At its opposite end, the grip lock connector includes female mating threads which receive male threads at a top location of a fire sprinkler.
