Garlock PS-SEAL® Reverse Lip

Reversed lip for special flow directions.

The Reverse Lip version features a sealing lip oriented in the opposite direction, making it ideal for applications where pressure or media flow from the outside inward, or where conventional lip configurations are insufficient.

Benefits:

• Specifically designed for reversed pressure directions

• Available in various PTFE-based lip materials

• Flexible configuration based on PS-SEAL Standard

Applications: Vacuum chambers, external pressure systems, specialized pumps.
