BSP Parallel Male x BSP Parallel Male 90° Compact Elbow

Parallel BSP at both ends in a tight 90° body. Used where two BSPP ports or swivel-nut hose ends need joining at a right angle on Australian and British-built equipment, and where a bonded washer or cone does the sealing rather than the thread.

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

Thread Standards

• 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

• A parallel thread cannot seal on itself. Each end needs either a bonded seal washer under the shoulder or a 60° cone seat in the mating part.
• Do not substitute BSPT here. Tapered male into a parallel female will bind part way and never seal properly.
• Compact bodies keep length down. Where the hose needs a gentler entry, look at the swept option instead.

Where You’ll Find It

• 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

• 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.

Technicians Advice

The most common failure on a BSPP joint is the bonded washer being left off or reused flat. It is a two dollar part that holds the whole joint, so fit a fresh one every time and make sure the port face is clean and square before you wind it down.
