G-ST-P/K Gaskets

G-ST profile gaskets for plastic flanges

Kroll & Ziller is your supplier for rubber-steel profile gaskets for plastic flanges. These can be freely selected from our various elastomers such as EPDM-EL, NBR-DUO-EL, CSM and many other elastomers. The profile gasket for plastic flanges is used in numerous application areas – from water and gas supply , fire protection and the chemical industry to mining , all plastic flanges thus remain reliably sealed.

The additional profile not only provides better gasket properties, but also ensures reliable gasket performance for plastic flanges at lower tightening torque levels. In addition, the profile can compensate to a certain extent for unevenness and damage to the gasket surfaces, misalignment of the flanges or gap dimensions.

In the G-ST-P/K, the K stands for plastic. The G-ST-P/K differs from G-ST-P/S in its dimensions, which are specially adapted to the dimensions of the gasket surfaces of plastic flanges. The dimensions do not fit? No problem either, our G-ST-P / OE can be freely dimensioned according to customer requirements.

Your advantages when using profile gaskets for plastic flanges

  • Sealed with small screw tightening torques
  • Compensation of surface defects
  • Flange and screws can be designed weaker
  • Service life of plastic flange connections is significantly higher (consideration of creep behavior)
  • Angular deviations can be compensated more easily compared to simple flat gaskets
  • Expensive grooving for round cord ring groove or offset grooving on the flange can be omitted
  • Profile gasket is available in different dimensions according to various standards, e.g. DIN EN 1514-1, DIN 2690, ASME-B 16.21, for VCI vessel flanges and many others.
