WHAT IS A HOLLOW CORE O-RING AND WHY IS IT USED?

ENCAP-O-SEAL hollow core o-rings are manufactured using two components: (1) a Teflon encapsulation (i.e. jacket or covering) and (2) an elastomer (rubber) hollow core material, which is completely enclosed within the Teflon encapsulation. M-COR, INC. encapsulates hollow-core o-rings to create a softer durometer seal. When the durometer is decreased, the amount of clamping force needed to effect a seal is reduced. The durometer of our standard hollow core ENCAP-O-SEAL o-ring is decreased approximately 10%. M-COR, INC. can design special core configurations to meet durometer requirements. Engineers specify ENCAP-O-SEAL hollow core o-rings in applications where clamping force is minimized due to other mechanical design considerations. Example applications would be ID/OD static or dynamic cylinder o-ring glands, hand tightened lids, caps, etc.
