ORFS Straight Fittings | Parker Seal-Lok™

Seal-Lok tube fittings (also known as flat face, O-ring face seal or ORFS fittings) have been proven to be very effective in eliminating leakage at higher pressures found in today's hydraulic systems. Parker Seal-Lok fittings meet or exceed the requirements of SAE J1453 and ISO 8434-3.

Parker Seal-Lok fittings feature a captive O-ring groove (CORG) design for optimal sealing, and prevention of O-ring fall-out prior to final assembly.

Parker O-ring face seal tube fittings are available in steel, stainless steel and 316 stainless steel.
