What is the O RING?

Sunpass FEP-encapsulated ‘O’ rings have a resilient core of silicone (VMQ) elastomer completely covered with a bleedline-free sheath of FEP fluoropolymer.

 

They are fully interchangeable with standard elastomeric ‘O’ rings and solid PTFE ‘O’ rings.

 

Advantages:

Excellent chemical resistance to a wide range of fluid media.

High level of hygiene for use with foodstuffs and edible oils.

Far better elasticity and seal ability than solid PTFE rings.

Operational temperature range of -60 to +200.
