PTFE envelopes
The most convenient solution for mild chemical protection is a PTFE envelope for our gaskets.
These envelope covers can be V or U-shaped. In Coestan we produce the covers in standardized dimensions or can meet your demand: with stainless steel corrugated core and compressed-fiber gaskets, rubber gaskets or graphite gaskets. We can also produce envelopes with a square profile.
