Rubbergasket with steel insert G-ST

The G-ST-P profile gasket range illustrates the technological progress of KROLL & ZILLER. The basic concept is very clear in the graphic illustration of the gasket crossection. The G-ST main body is combined with a round cord ring. This “O-ring” is the most static sealing element. The performance of this O-ring is almost miraculous even without a cost-intensive groove. The G-ST-P profile gasket combines the advantages of its individual parts. High surface pressures transmitted from the main force of the flow are absorbed by the rigid body of the G-ST gasket. The flat steelring, corrosion protected by being vulcanized in, absorbs with ease the required test pressure. The Oring lying parallel to the main force of the flow is ideally compressed against the sealing faces even at low surface pressures. Irregularties and grooves, even slight misalignments are compensated. As well, the gasket shows insensitivity to the minimum torques required during installation which spares the material. A degree of operating reliability - never before reached - is assured. Once in position - it is sealed tight! These advantages are especially important for flange joints of thermoplastics (PVC, PE, PP, PVDF). The special KROLL & ZILLER gasket G-ST-P/S has the following advantages:

· wide sealing surface area

· rectangular instead of round cross-section near the O-ring

These attributes prevent deformation of the flange adapters. The round cord ring reliably fills the enlarged gap. Minimum required tightening torques protect the joining elements from being overloaded.
