Rubber-steel gaskets

Rubber-steel gaskets are used wherever effective sealing of comparatively cool substances is combined with low leakage rates and low bolt forces.

Rubber-steel gaskets are mainly used to seal gas, water, air, acids, alkalis and hydrocarbons in combination with low pressures and temperatures.

The inner steel ring prevents the seal from being pressed out at prevailing pressures and thus increases the stability of the seal even during the most difficult assembly tasks.

Type HST-GST-WG
 
Rubber-steel gasket with inner metal core surrounded by rubber
  • low leakage rate due to the homogeneous rubber casing

  • due to the soft and flexible sealing surface, the gasket can even seal with slightly damaged flanges

Type HST-GST-WG2
Rubber-steel gaskets with inner metal core surrounded by rubber
with double sealing lips
  • high sealing efficiency at low bolt forces, making it particularly suitable for plastic flange connections

  • highly leak-proof due to the self-sealing effect of the sealing lips under internal pressure

Type HST-GST-KH
 
Rubber-steel gasket with centering ring surrounded by rubber with double sealing lips
  • easy to handle the rubber sealing material, due to steel centering ring -even at large nominal sizes

  • highly cost efficient, due to the simple replacement of the rubber lips and possibility to reuse the rubber-steel gasket

Type HST-GST-KN
 
Rubber-steel gasket with support ring and rubber sealing lips

  • excessive compression of the rubber ring is impossible due to the chambering of the metal supporting ring

  • gasket is sealing secure, even with large fluctuations or surges in pressure
