FIELD: mechanical engineering.
SUBSTANCE: coupling comprises metallic housing with two oppositely directed cylindrical grooves that receive mechanisms for sealing the butt and locking the pipe. The mechanisms are made of a rubber ring spacer that is compressed when the pressing conical ring moves. The mechanism for locking pipe is made of a step-shaped cylindrical bushing that is divided into tubs.
EFFECT: enhanced reliability.
