SPLIT RING – The main purpose of this component is to ensure optimum grip between the fitting system and the pipe. Internally, several sharp triangular teeth are applied and are in contact with the pipe when inserted into the fitting system. Externally, the conical ribs progressively tighten on nut’s internal cone exerting the necessary gripping force on the pipe, ensures that no pull-out or disassembly will appear during operation. Made by high-performance polyacetal material with sufficient stiffness and hardness to provide high-end load resistance. Can be used to join all types of polyethylene pipes.
