Seal-Lok Products
Reliable, Durable, Leak-Free Connection Solutions
Parker's Seal-Lok O-Ring Face Seal (ORFS) Fittings and Adapters meet or exceed the requirements of both SAE J1453 and ISO 8434-3 and have international acceptance. It is an ideal hydraulic fluid connection solution across many markets due to its key advantages:
- Zero clearance for easy plumbing
- Resistance to over torque/eliminated damage from over-tightening
- Vibration resistance/reduced loosening caused by system vibration (see vibration test data)
- Flat face for unlimited remakability
Seal-Lok ORFS fittings also come standard with the exclusive Trap-Seal which protects against O-ring fallout and O-ring pinch, both potential issues with the ORFS design. Additionally, Seal-Lok steel tube fittings and adapters come standard with ToughShield Plus zinc-nickel plating which resists red rust for up to 3,000 hours tested to ASTM B117/ISO 9227.

The Seal-Lok ORFS Difference
Parker's Seal-Lok ORFS fittings and adapters are designed and engineered with innovative enhancements that ensure the most superior leak-free connections for customer's applications, minimizing downtime and maximizing their bottom lines.
Trap-Seal
Parker's patented Trap-Seal design prevents o-ring fallout during shipping and assembly, as well as prevents seal pinch during assembly - the two most common ORFS issues.
SAE Robust Port Stud
Parker's exclusive Robust Port Stud on adjustable SAE ports is manufactured with a longer locknut virtually eliminating washer damage and potential leaks, as well as making assembly virtually mistake-proof.
Seal-Lok for Every Application
Maximizing the benefits of the ORFS fitting design, Parker created two new versions. Seal-Lok for CNG provides industry-approved fuel conveyance in natural gas applications. Seal-Lok Xtreme’s patented metal seal achieves leak-free connections in extreme temperatures, perfect for LNG or cryogenic.
ToughShield™ Plus
ToughShield Plus, Parker's standard zinc nickel plating on all steel tube fittings & adapters, resists red rust significantly longer than other commercially available plating technologies. It extends fitting service life, decreases corrosion migration to adjacent components, and reduces maintenance.
