Thread Standards

• ORFS Bulkhead Male – SAE J1453 O-ring face seal on a bulkhead body with a locknut. It seals on the O-ring in the flat face; the bulkhead thread and locknut only clamp the part to the panel.
• ORFS Male – SAE J1453 O-ring face seal. It seals on an O-ring sitting in the flat face groove, never on the thread.

How to Choose

• The bulkhead thread and locknut clamp the fitting to the panel. They do no sealing, so do not try to cure a leak by tightening the locknut.
• Check your panel hole size and thickness before you order. The body has a set thread length under the shoulder and a thick panel eats it.
• The bend is fixed, so decide the orientation before the locknut goes tight.
• Both ends seal on an O-ring in a flat face. Nothing on either thread.

Technicians Advice

Orientation first, locknut second, hoses third. And once it is all on, cycle the machine and watch where the hose sits under full travel rather than where it sat on the bench.

Where You’ll Find It

• ORFS Bulkhead Male – panel and chassis pass-throughs on late-model machinery built on ORFS – excavators, loaders and truck-mounted equipment where vibration rules out thread-sealed joints.
• ORFS Male – High-pressure, high-vibration circuits on late-model excavators, drill rigs, crushers and forestry gear.

Cross-Reference

• ORFS Bulkhead Male – SAE J1453 O-ring face seal, bulkhead style. Often written ORFS BH or O-ring face seal bulkhead. The face seal does the work, the locknut does not.
• ORFS Male – SAE J1453 / ISO 8434-3 O-ring face seal. Parker call this series Seal-Lok. Also written ORFS or flat face.

Parker, Gates, Aeroquip and Ryco all manufacture to these same standards under their own part numbering, so a fitting built to the standard above will mate with theirs.

Cross-references are given at series level as a guide to the standard, not as a part-for-part substitution. Always confirm the thread form, size and seal type against the port before ordering.
