High Temperature Metal Bellows Rotary

The Style 65 is similar to the Style 60, however it is designed to seal applications that exceed 400ºF / 204ºC. It is able to seal high temperature primarily because it uses a graphite wedge as a secondary seal rather than an o-ring elastomer. Special metallurgy is often required for these kinds of applications. Style 65 is not repairable.
