O-ring mounted stationaries are preferred for their versatility in elastomer selection, as well as higher operating limits in housings with higher manufacturing tolerances.
For the OG and W seats, the o-ring is centrally contained within the seat section. The rear makes direct contact
with the base of the housing recess, providing better heat transfer and dissipation. Provision for an anti- rotation pin is included via a rear slot, intended for use in specialised or viscous fluid applications.
