KLINGERSIL Hochdruckdichtung

KLINGER® top-chem 2000

Exceptional performance at high mechanical requirements

KLINGER®top-chem 2000 is a universal heavy-duty gasket, which offers an exceptional performance in applications with high mechanical requirements at high temperatures. The only PTFE gasket with a Fire-safe-certificate.

Basis

PTFE gasket filled with SiC (Silicon carbide).

Areas of application

Excellent resistance in strongly acidic and alkaline applications as well as to steam and oxygen. Suitable for an extremely wide range of applications in the chemical and petrochemical industry, as well as in the ship building industry for the transport of chemicals.

KLINGERSIL® C-4300 ist eine universelle Hochdruckdichtung.

Function and durability

The performance and service life of KLINGER gaskets depend to a large extent on proper storage and fitting - factors beyond the manufactor’s control. We can, however, vouch for the excellent quality of our products. With this in mind, please also take note of our Installation manual.
