Trap-Seals offer improved seal reliability by stopping O-ring from popping out of its face seal (ORFS) groove. Trapezoidal design provides consistently positive groove retention and creates a larger overlap between the groove lip and seal for retention. Reduces problems of costly leakage. Interchangeable with standard O-ring used in half-dovetail grooves for seal replacement.
