JIC 37° Male x JIC 37° Male x BSP Parallel Male Branch Tee

Two JIC male ports in line with a BSP parallel male on the branch. The common way a BSPP gauge, sender or pilot line is picked up off a JIC run on an Australian machine.

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

Thread Standards

• JIC 37° Male – SAE J514 37° flare. It seals metal-to-metal on the 37° cone, so it takes no tape at all.
• BSP Parallel Male – BSPP to ISO 228. It seals on a bonded washer against the port face or on a 60° cone, never on the thread itself.

How to Choose

• On a branch tee the two in-line ports carry the main flow and the third port comes off the side at 90°. Get that the wrong way round and the tee physically will not fit the run.
• The two JIC ports seal dry on the 37° cone. The BSPP branch needs a bonded washer or a cone seat in the port.
• Sealant on the BSPP branch only if the port design calls for it, and never on the JIC cones.

Technicians Advice

Fit the BSPP branch into its port first and get it seated, then bring the two JIC hoses on. Working the other way means you are loading the branch thread while the cones are still finding their seats.

Where You’ll Find It

• JIC 37° Male – Hose ends and ports on imported US and Asian machinery – Caterpillar, John Deere, Case IH, New Holland, Bobcat, Kubota, Takeuchi.
• BSP Parallel Male – Valve and manifold ports on Australian, British and Asian-built equipment, and most locally made hose ends. The default port thread on Australian truck and agricultural hydraulics.

Cross-Reference

• JIC 37° Male – SAE J514 / ISO 8434-2 37° flare. Parker call this series Triple-Lok. The industrial cousin of the AN 37° flare used in aviation and motorsport.
• BSP Parallel Male – BSPP to ISO 228 / BS 2779, written G. Also called BSP parallel or gas thread.

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.
