ORFS | Parker Seal-Lok™
O-Ring Face Seal (also referred to as ORFS or Face Seal) fittings are very effective in eliminating leakage in applications involving higher pressures, vibration and impulse.
Seal-Lok's O-ring captive groove is engineered to work with Parker’s trapezoid O-ring to minimize a chance of the O-ring popping out of the groove.
ORFS fittings are readily adaptable to pipe, inch or metric tubing and hose.
