BSP Tapered Male x BSP Tapered Male x BSP Swivel Female Branch Tee

Two BSPT male ports in line with a BSP swivel female on the branch. Lets a hose come off the side of a threaded BSP run without twisting as you tighten it.

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

Thread Standards

• BSP Tapered Male – BSPT to ISO 7 / BS 21. It seals on the tapered thread itself, so it needs PTFE tape or a liquid thread sealant.
• 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.

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 tapered males seal on the thread and need sealant. The swivel female seals on its 60° cone and does not.
• Do the tapered ends first, then wipe your hands before you handle the cone.

Technicians Advice

Sealant carried onto the swivel cone from the tapered ends is the classic tee mistake. It holds on a pressure test and seeps once the machine is working. Two ends with sealant, one without, and clean hands between them.

Where You’ll Find It

• BSP Tapered Male – Older Australian and British pipework, gauge ports, tank and return lines, and cast pump and gearbox housings.
• BSP Swivel Female – Hose ends across Australian-built assemblies, and anywhere a joint has to be broken and remade repeatedly.

Cross-Reference

• BSP Tapered Male – BSPT to ISO 7 / BS 21, written R for male. Sometimes labelled PT or BSP taper.
• BSP Swivel Female – BSPP body to ISO 228 with a 60° cone seat. Commonly called a BSP swivel or BSP female cone seat.

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.
