Rubber-Steel Gaskets and Flange Connections from Kroll & Ziller
Rubber-steel flange gaskets from Kroll & Ziller are used for the secure sealing of flange connections in all areas of pipeline construction.
The rubber-steel flange gaskets have a steel insert vulcanized into an elastomeric material. During vulcanization, extreme adhesion is achieved between the steel core and the rubber coating. Even under the highest stresses, this makes it impossible to shift, detach or blow out.
Depending on the respective elastomer, the flange gaskets can be used in a wide range of applications and are suitable for water, steam, gas, air, acids, alkalis, hydrocarbons, among others, whereby operating temperatures of up to approx. 200 °C are possible. Rubber-steel gaskets meet the requirements of TA Luft and, depending on the material, various other requirements such as the requirement for use in drinking water, the gas sector, food technology and many other industries.
Your advantages when using rubber-steel-gaskets
Tightness even at low surface pressure (even at low tightening torques)
Very good adaptability to the sealing surfaces
Low leakage rates thanks to homogeneous structure of elastomeric materials
Blow-out safety and maximum stability due to centrally positioned, corrosion-protected and vulcanized steel inlay
Optimum handling when installing the gasket

Variants of rubber-steel flange gaskets
Various elastomers are available for our rubber-steel flange gaskets:
NBR-DUO-EL (Acrylonitrile butadiene rubber)
With approval for drinking water and gas supply in accordance with the applicable standards and regulations.
With approvals for drinking water in accordance with DIN-EN-681-1, as well as other requirements in the automotive industry through to power plant and air conditioning technology.
EPDM(Etyhlen Propylene Diene Rubber)
Thanks to its excellent chemical resistance and good strength values, EPDM is used in almost all areas – from vehicle construction and the building industry to conveyor belts, industrial hoses and flexible piping.
HNBR (Hydrogenated acrylonitrile butadiene rubber)
Due to the very good aging resistance and mechanical strength, this material is particularly suitable for use at high temperatures and mechanical loads.
CSM (Chlorosulfonated polyethylene)
The chlorine in the CSM provides good flame retardancy and mineral oil resistance. Furthermore, CSM is characterized by good chemical resistance.
CR (Chloroprene rubber)
This material is used in particular where high resistance to oils, greases, low temperatures, embrittlement and the effects of weather and ozone are required.
IIR (Butyl rubber)
Very low gas permeability (air, water vapor and other gases), good resistance to heat, ozone, oxygen and chemicals give this material good sealing properties.
Especially when high resistance to chemicals and high/low temperatures is required, FKM is the first choice. In vacuum applications, FKM ensures best results due to its good gas density.
