Parker Seal Lok Fittings

Parker's Seal-Lok O-Ring Face Seal fitting design provides leak-free connections in applications with high-pressure, vibration and impulse environments. The Seal-Lok fitting is an O-ring face seal type fitting that consists of a nut, a body, an O-ring and a sleeve. Using the new FastSeal nut, ORFS tube connections can be made in minutes without flanging or brazing.

Parker's O-ring Face Seal (ORFS) Tube Fittings and Adapters meet or exceed the requirements of both SAE J1453 and ISO 8434-3 and have international acceptance. O-ring face seal fittings offer zero clearance, resistance to over torque and vibration resistance making it an ideal reusable hydraulic fitting solution across many markets. Seal-Lok tube fittings and adapters come in steel and stainless steel. Parker's Trap-Seal for ORFS improves customer experience by eliminating potential hydraulic leaks caused by O-ring fall-out and O-ring pinch during assembly. This provides customers a competitive advantage while leading to reduced overall cost.


• Highly resistant to over-torque, withstanding 200% torque above the rated value without any damage to the fitting, creating unlimited reusability.
• Flat sealing surface allows for zero clearance installation.
• Suitable for a wide range of wall thicknesses and are adaptable to inch tube, metric tube and hose.
• Patented Trap-Seal design provides optimal seal retention in ORFS CORG groove and prevents seal pinch during assembly.
