Low-Pressure Hose Tail – BSPP Male Fixed – 90° Compact Elbow – Crimp-On

A low-pressure BSP parallel male on a 90° compact crimp tail, for tight return and tank line routing.

Mild steel body with a plated finish, manufactured to the standard listed above.

This is the tail only – clamps are sold separately

Low-pressure tails are not crimped. They push into the hose and are held with a worm drive clamp over the barb. There is no ferrule and no crimp diameter to set.

• Cut the hose square and push it fully onto the barb, past the last serration.
• Position the clamp over the barbed section, not over the plain shank behind it.
• Nip it up until the hose swells slightly between the serrations. Over-tightening cuts the cover and starts a leak path.
• Two clamps on larger bores, spaced along the barb, on suction and return lines that see vibration.

Thread Standards

• BSP Parallel Male – BSPP to ISO 228, seals on a bonded washer against the port face or on a 60° cone, never on the thread itself

How to Choose

• The bend is formed into the tail, so the angle is fixed. Decide which way the hose has to leave the port before you order – you cannot rotate it after it is crimped.
• Low-pressure duty only.
• Needs a bonded washer or a cone seat in the port – the parallel thread does not seal on itself.

Technicians Advice

Nip the joint up until the washer just squashes and stop. Leaning on a bonded washer to cure a weep flattens it out and you lose the seal you were trying to make.

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.

What “low pressure” means here

• These tails are built for the low-pressure side of a system – return lines, case drains, suction lines and tank lines.
• They are not a substitute for a braided-hose pressure tail. If the line sees pump pressure, use a two-piece tail on 1‑wire or 2‑wire hose instead.
• The working pressure of the finished assembly is set by the lowest-rated part in it – usually the hose. Check the hose rating and match the tail to it, not the other way round.
• Suction and return lines run at low pressure but move a lot of oil. Size on bore and flow, not on the thread you happen to have spare.
