Dielectric coupling "STM", for gas eyeliner, external/external thread 1/2 "
A direct dielectric coupling with external thread is an unlimited fitting that is an isolating obstacle to the passing of wandering currents through gas pipelines.
the coupling is installed on the area between the shut -off and consuming equipment that has an electronic “filling” (boiler, counter , a stove, a fireplace, etc.).
a dielectric coupling is a design of two fittings interconnected using an insert made of non -combustible composite material - glass -filled polyamide. The indiscretion of the coupling guarantees the absence of gas leakage during operation.
the coupling is characterized by high strength and chemical inertia. For the manufacture of threaded metal parts of the coupling, brass is used, unprofitable to corrosion processes.
the dielectric coupling is designed for operation with a working pressure of up to 0.6 MPa. Environmental temperature: -20...+80 ° C. The coupling is able to withstand voltage up to 3.75 kV for 6 seconds. Electric resistance of the dielectric coupling - 5 MOM.
