Product Detail

PEEK OFS ID Face Seal

ID Face Seals for gate valves are spring-loaded, pressure-energized lip seal that improve gate and seat service life.

It is an end face mechanical seal with both rigid and flexible elements, which gives consistent contact at the sealing interface. ID face seals and OD face seal are combined used for valves.

JST ID/OD face seal is spring loaded with a pressure energized lip seal. It is used for the valve seat.

JST provides ID/OD face seals with two different materials. A common option is virgin peek spring energized by a stainless-steel spring. Another option is glass moly filled PTFE with stainless steel springs, which are very durable and can withstand the worst conditions. When conditions are not extreme, a more cost-effective material option is glass moly filled PTFE. This ID/OD face seal is a good choice and has very good durability.
