Unlike the standard round-shaped O-rings that rely on the O-ring being pinched by the groove retaining lip for seal retention, the Trap-Seal is designed to stay securely lodged under the ORFS groove lip. Trap-Seal's unique trapezoidal design provides consistently positive retention in the groove and creates a larger overlap between the groove lip and the trapezoidal seal for increased retention. This improved reliability reduces potential problems of costly leakage and/or time-consuming pre-assembly handling.
Trap-Seal is interchangeable with the standard O-ring used in half-dovetail grooves, making seal replacement in the field quick and easy. Trap-Seal's improved reliability also will help reduce the need to repeatedly replace or reinstall O-rings that are missing, damaged or not properly seated in the groove.
The Trap-Seal Advantage:
- Greater seal retention
- Reduced risk of seal damage and leakage
- Smoother pre-assembly process
- Interchangeable with O-rings in standard SAE J1453 half-dovetail groove
- Provides same material and hardness as Parker's standard O-ring (90 Durometer Nitrile)
