Square Bore Type Mechanical Face Seal Better Mud Packing Behavior

The mechanical face seal type 76.95 consists of two metallic angular seal rings with identical contours. The seal rings are assembled with trapezoid elastomer parts positioned against the housing bore. Type 76.95 provides stiffer spring characteristics than standard o-ring designs.

The HSL seal is an evolution and special form of the square bore seal. It uses a unique and patented design for the elastomeric part of the seal with an integral dirt exclusion lip and heavy-duty spin protection. These features improve protection significantly, leading to reduced leakage, extended service life and resisting compression from mud.
