BSP Tapered Male x BSP Tapered Male 45° Compact Elbow

Male-to-male 45° compact elbow in BSP tapered thread. Screws straight into a port at one end and takes a female fitting or swivel hose tail at the other, angling the line 45° in the shortest body available. A workshop staple on Aussie-built tippers, truck bodies, Kanga and Dingo loaders, Merlo, Manitou, JCB and general farm machinery.

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.
• BSP Tapered Male – BSPT to ISO 7 / BS 21. It seals on the tapered thread itself.

How to Choose

• Check both numbers – the two male ends are often different sizes on a reducing elbow.
• Goes port-side into pumps, valve blocks, cylinders and manifolds.
• Compact where clearance is tight; choose swept for better flow on long runs.

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.

Cross-Reference

• BSP Tapered Male – BSPT to ISO 7 / BS 21, written R for male. Sometimes labelled PT or BSP taper.

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

Two tapered males means two sealed joints and two chances to overtighten. Tape both, wound with the thread and set back from the leading edge, and pull each up to where the taper bites rather than to a number. Fit the port end first and let the elbow find its angle as it tightens – if the angle lands wrong, add or remove a wrap of tape rather than backing the fitting off, because backing off a tapered thread breaks the seal.
