BSP Swivel Female x SAE O-Ring Boss Male 90° Compact Elbow

O-ring boss into an American port, BSP swivel female out to a local hose, at 90°. This is the fitting that lets an imported pump or valve run standard Australian BSP hose without re-hosing the machine.

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

Thread Standards

• BSP Swivel Female – BSPP to ISO 228 with a 60° internal cone seat. It seals on the cone and swivels, so it needs no tape or sealant.
• SAE O-Ring Boss Male (UNO/UNF) – SAE J1926 / ISO 11926 straight thread O-ring boss. It seals on an O-ring squeezed against the port spotface, not on the thread.

How to Choose

• The ORB end needs a machined boss with a spotface. It will not seal in a tapered port.
• The BSP swivel end seals on a 60° cone and takes no tape.
• Check the ORB O-ring is present and correct for the fluid before winding it in.

Where You’ll Find It

• BSP Swivel Female – Hose ends across Australian-built assemblies, and anywhere a joint has to be broken and remade repeatedly.
• SAE O-Ring Boss Male (UNO/UNF) – Cylinder end caps, pump and valve bosses on US-built plant. Common on Australian-assembled cylinders too, where it is usually called UNO.

Cross-Reference

• BSP Swivel Female – BSPP body to ISO 228 with a 60° cone seat. Commonly called a BSP swivel or BSP female cone seat.
• SAE O-Ring Boss Male (UNO/UNF) – SAE J1926 / ISO 11926 straight thread O-ring boss. Also written ORB, SAE ORB or UNO. Thread form is UN/UNF.

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.

Technicians Advice

Neither end of this fitting is tapered, so if it seeps the cause is a damaged seal, not not enough torque. Reaching for a longer bar will extrude the boss O-ring and score the swivel cone, turning a five minute reseal into a new fitting and a damaged port.
