ORFS Male Equal Tee

Three O-ring face seal male ports. The tee to have where a machine shakes hard, because there is no thread sealant to work loose.

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

Thread Standards

• 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

• All three ports are the same size and thread, so it does not matter which way the tee goes in.
• All three ports seal on an O-ring in the mating flat face. Nothing goes on any thread.
• ORFS thread size and line size are different numbers, so work to the dash size on the hose.

Technicians Advice

ORFS earns its place on high-vibration mounts, but only if the rings are right. Look into all three faces before the tee goes near the machine, because the one facing away is the one that will catch you out.

Where You’ll Find It

• ORFS Male – High-pressure, high-vibration circuits on late-model excavators, drill rigs, crushers and forestry gear.

Cross-Reference

• 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.
