KGS GII rubber-steel gaskets are available in a wide range of materials, including EPDM, NBR, NR, CSM and FKM. KGS GII gaskets feature high-strength rubber-metal bonds, as well as optimised cross-sectional profile and rubber-steel ratios, enabling the seal to absorb significantly higher flange forces than other gaskets, says the company. In a first for a rubber-steel gasket, an exact centering of the steel ring was achieved during the molding process of the gasket. Therefore, the leverage forces are spread homogeneously during flange mounting and the force application is symmetric.
The geometry is chosen so that even at the lowest gasket loads, safe sealing occurs. The gasket can also absorb extremely high static loads due to short compensation movements of the rubber. This means that the flange connection will become significantly safer at higher bolt and pipe forces. Special reservoir areas are designed so that even at the highest possible compression, no intrusion of the rubber into the internal tube diameter or extrusion into the outer centering area will occur.
The KGS GII KBR version (photo) exhibits good resistance against aliphatic hydrocarbons, mineral oils and fats, as well as fuels. Therefore, this gasket is well-suited for media containing hydrocarbons and combustible gases as well as hydrogen. This gasket can also be used for wastewater and industrial water systems.
Approvals and certificates for the KGS II NBR include: DVGW-Certificate according to EN 682 GBL; EN 681–1 WG Class 70; EN 682 GBL Class 70; and the TA-Luft (Clean Air Act).
The KGS GII EPDM version demonstrates chemical resistance, as well as stability against ozone, aging and environmental effects. Due to its approvals, the gaskets can be used with potable water systems. Approvals and certificates for the KGS GII EPDM version include: EN 681–1 WAL/WCL Class 70; Elastomer-Guideline (new KTW-BWGL); DVGW W270; ACS, WRAS (BS6920); and TA-Luft (Clean Air Act).
