EBS Elastomer Seal

The EBS Seal is a self-energized, elastomer seal that requires no injection. The elimination of injection means it can be used in applications where the traditional seal energizing pressure would exceed the collapse pressure of the casing.

The EBS seal element is used both in integral secondary seal and packoff bushing configurations and is rated up to 15,000 psi when used as an integral secondary seal.

Features –

Quick to install
Self-energized seals do not require injection
Anti-extrusion barrier molded into the seal's body
Bidirectional seal
Available for use over casing sizes from 4-1/2" through 13-5/8"
Materials are suitable for CO₂ and H₂S service
