RTJ RING JOINT GASKETS

RTJ RING JOINT GASKETS

RTJ joint gaskets are metal sealing rings used at high pressures up to 1500 bar and temperatures up to 1000oC. They are used in combination with special flanges, which provide adequate sealing with the right choice of material and profile. They are available in two basic profiles: oval (MB) and octagonal (M9).
