Coseal Type 2702 Mineral fiber, Organic fiber, Inorganic fillers, Metal Reinforced and NBR

Basis

A gasket material formulated with mineral fiber, organic fiber, and inorganic fillers, reinforced with steel wire and bonded with an NBR binder.

Application

A versatile, metal-reinforced gasket designed for medium-pressure applications involving steam, water, oils, fuels, and inert gases under low-stress conditions.

Area of Application

Suitable – The gasket material is typically suitable when chemically compatible with the application.
Conditionally Suitable – The material may be appropriate, but professional technical consultation is advised prior to use.
Not Recommended – Installation should not proceed without comprehensive technical evaluation.
