Power-Lock seal is integrated into the pipe during the manufacturing process. By heating the pipe and using the mandrel together with the seal as a tool to form the socket, the seal is effectively shaping its own groove. This reduces irregularities and tolerances in the socket.
The seal is equally effective under positive and negative pipe pressure (vacuum). Under positive pressure, the higher the pressure the greater the sealing force. Under vacuum, the seal maintains a positive sealing force against spigot and socket, preventing sand or soil to enter the joint.
The Power-Lock is a composite seal consisting of a flexible rubber element to seal effectively against the spigot and socket and a polypropylene reinforcement element, which holds the seal firmly in place.
The system meets the requirements of European and American Standards for the supply of water, pressure vacuum and shear load.

Joint Assembly
Inspect the spigot, socket and seal for damage and remove any dirt or dust prior to assembly. Chamfer the spigot end and remove all burrs.
Apply lubricant to the spigot end and immediately bring it into contact with the socket.
Align spigot and socket, and slide the spigot into the pipe, past the seal.
