Style 65 High Temperature Metal Bellows Rotary

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.
