Product Description
Klinger® gasket materials are our top choice for compressed fibre and asbestos replacement gaskets. Developed in 1886, Klinger® materials are known for their quality and reliability, suitable for a wide range of applications and environments. Many of these grades comply with BS7531 standards and are widely used in industries such as aerospace, chemical, petrochemical, power generation, oil, and gas. Their versatile properties make them ideal for nearly any sealing application.
Our Klinger non-asbestos gaskets have been designed to provide the same excellent resistance properties found in asbestos based gaskets, without any of the drawbacks. This creates a product which offers far superior safety as well as durability properties. Unlike asbestos based gaskets, Klinger gaskets are 100% safe for human contact.
