Did you know? 60° / 55°

NPT and BSPT have different flank angles, 60 against 55 degrees. They will screw together for a few turns and still not seal reliably.

Tube fittings

Pneumatics

Tube fittings form the detachable joint between pipe, hose plus equipment port in pneumatic as well as hydraulic systems. This section holds 9808 items in 44 groups, ranging from straight male stud couplings through elbow, tee, cross shapes to bulkhead glands, push-in fittings, along with the matching tubes.

Selection follows the port thread (G 1/8" to G 1/2", R 1/8" to R 1/2", metric), the tube or hose size, then the material. Tube sizes run from 4 LL (M8x1) up to 18 L (M26x1,5), hose sizes from 6x4 to 12x10 mm, in nickel plated brass, stainless steel 1.4404 or polypropylene. Beyond the standard version there are variants having a stainless steel thread, a collar, plus a high temperature design.

Tube fittings serve machine building for compressed air distribution, cylinder plus valve ports, also hydraulic control lines. Bulkhead unions lead lines through housing panels or control cabinets, weld-on parts as well as press fittings join fixed pipe runs. On vehicles the ABC, BRK systems connect plastic lines for brake circuits plus air supply. Miniature push-in fittings from thread M 5 upwards suit grippers, handling axes where installation space stays tight.
