Profile rings, that are almost maintenancefree, for severe temperature changes and/or extreme temperatures, which cannot be handled with elastomeric O-rings.
Grafopak Profile rings provide good deformability, permanent resilience, long-term flexibility and good structural strength.

Application

Pressed rings of expanded pure graphite for static sealing of machine parts in high temperature applications and with temperature cycles, e.g. in heating and cooling systems, heat exchangers, valves or in pumps as seal for casing.

Design

Permanently elastic, expanded graphite ( > 99,8% graphite) without binders or fillers.
