KLINGERSIL® C-4409

More safety at high thermal and mechanical stress

KLINGERSIL C-4409 offers more safety at high thermal and mechanical stress. Due to the expanded metal, this special high-pressure gasket is suitable for high loads.

Basis

Synthetic fibers bonded with NBR.

Areas of application

Chemical resistance to oils, water, steam, hydrocarbons as well as to liquid and gaseous chemicals.

Key features

Expanded metal reinforcement
Improved stress relaxation

Benefits

Suitable for higher pressures
Higher resistance against blow-outs
More safety at high internal pressures
