ORFS Bulkhead Male x ORFS Male 90° Compact Bulkhead Elbow

An ORFS bulkhead body with a 90° compact bend to an ORFS male. The face-seal pass-through elbow, for machines that shake hard and need the line turned at the panel.

Brand: Ayrtec – mild steel body with a plated finish, manufactured to the standards listed below.

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 set the orientation before you tighten the locknut.
• Both ends seal on an O-ring in a flat face. Nothing on either thread.

Technicians Advice

Angle first, locknut second, hose last. Face seals are the right choice on a shaking machine, but only if the hose is not being pulled sideways into the ring by a badly aimed elbow.

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.
