Extra long coupler with integrated Gas-Stop Piреlife

Extra long coupler with integrated Gas-Stop Piреlife. Elongated coupling with a special integrated Gas-StopTM safety system designed for timely automatic blocking of the gas flow in case of damage to the pipe, any equipment. They have a special open heating spiral for better heat transfer, a greater depth of conjugation, a wide welding zone, cold zones on the sides and in the center, preventing the leakage of the molten mass, do not require special positioners and devices. Coupling universal type U execution optimally satisfies the requirements in relation to working pressure and medium volume flow. The a/ D and Uue types have a bypass device.
