Threaded fittings, camlock and push‑in.
Class 150 threaded fittings in SS316, camlock couplings in stainless, aluminium and brass, and AF Hydro push‑in fittings for 4 mm to 12 mm nylon and PU tube. Three different ways to make a joint you can break again on site — no welding on any of them.

Class 150 threaded fittings are for the permanent stainless pipework. Camlock is for a hose end that gets broken often — two cam arms and no tools, which is why it is standard on tanker discharge, transfer hoses and washdown lines. Push‑in is for small‑bore plastic tube on compressed air and pneumatic circuits, where the layout changes and the tube count is high.
Getting the specification right
Which line suits the joint, and the four things we need in order to quote it.
Choosing between them
- Class 150 fittings — SS316 elbows, tees, sockets, unions and the rest, threaded NPT or BSPT to 150 PSI. For fixed pipework you assemble once.
- Camlock couplings — to 250 PSI, and the highest‑rated of the three. For anything that gets connected and disconnected in service.
- Push‑in fittings — 4 mm to 12 mm nylon or PU tube at 0 to 1.0 MPa. No thread and no tool: push the tube in, press the collar to release it. For compressed air, pneumatics and instrument lines.
- Camlock material — SS316 for corrosive or hygienic duty, aluminium where weight matters on a hose end, brass for general water and air.
- Thread form matters — NPT and BSPT are not interchangeable. If you are adding to an existing run, match what is already there. Push‑in fittings have no thread at all — there the tube OD is the whole specification.
What to send us
Four things and we can quote without going back and forth:
- Size — nominal thread or hose size, or the tube OD in mm for push‑in.
- Fitting type — elbow, tee, socket, union, the camlock coupler type (A, B, C, D, E, F or DP), or the push‑in shape.
- Material — SS316, aluminium or brass; and for push‑in, whether the tube is nylon or PU.
- Thread form — NPT or BSPT; for camlock, whether you need a hose shank instead; for push‑in, nothing — there is no thread.
Send the whole schedule rather than one line at a time — fittings are almost always priced better as a set.
Catalogues
One catalogue for each of the three lines, all from AF Hydro. Direct PDF downloads, no form.
What is in them
- Dimensions — thread size, hex, overall length and weight, per size.
- Ratings — working pressure by size and by material.
- Thread forms — NPT and BSPT, and which sizes each is available in.
- The full fitting range — elbows, tees, sockets, unions, nipples, plugs, caps and bushes, with part numbers.
Before you download
- They open in a new tab. Nothing is gated: no form, no sign‑up, no email address.
- Dimensions and ratings are in the catalogue; stock and price are not. Send us the list and we will confirm both.
- Fittings are usually ordered as a schedule rather than one at a time — send the whole list and we will price it as one.
