Hydraulic Adaptors
Filter by type, thread or fitting angle. Thread and angle narrow the results together (e.g. BSP and Straight); within Type, picking several shows any of them.

About Hydraulic Adaptors
Hydraulic adaptors connect, adapt and redirect fluid between different thread types, sizes and angles. Our range spans BSP, JIC, NPT, ORFS, Metric and UNO threads in nipples, swivels, elbows, tees, reducers, bulkheads, caps and plugs – filter by type, thread and angle to find the exact fitting. Not sure what you’re looking at? Our thread identification guide walks you through it.
Frequently asked questions
How do I identify a hydraulic fitting thread?
Check four things - the thread form angle, whether it's parallel or tapered, the diameter, and the threads per inch - then match them against a chart. Our thread identification guide walks through it step by step.
Are BSP and NPT interchangeable?
No. They use different thread forms (55° vs 60°) and won't seal together, even though some sizes will start to thread. See BSP vs NPT for the detail.
What's the difference between a male and female adaptor?
A male adaptor has external threads; a female has internal threads. You pair a male with a female of the same thread type and size.
What does a swivel adaptor do?
A swivel end rotates, so you can tighten the connection without twisting the hose or spinning the whole fitting - handy where components can't rotate.
Can you adapt between two different thread types?
Yes - that's exactly what many adaptors do (for example BSP to JIC). Identify both threads, then choose an adaptor with the matching ends.
