About BSPP
British parallel pipe thread. The threads do not seal on their own, so a bonded washer, ED ring or O ring seals against the port face. Standard on European and Asian hydraulic pumps, valves and machinery.
ISO 228-1, ISO 1179. Seals by: bonded washer or ed seal.
About Hose barb
Barbed spigot for soft tube such as vinyl, silicone, PU and PE, sized to the tube inside diameter from 1/16 in to 1 in and 2 to 25 mm. Sharp ridges grip the tube; add a clamp or ferrule above 30 psi. Used for dosing, lab fluidics, coolant, aquariums, beverage and irrigation lines.
Hose barb, tube ID. Seals by: tube grips the barb ridges, clamp or ferrule for pressure.
One part, fewer leaks
A single machined adapter replaces a stack of two or three, so there are fewer joints to leak and the run is shorter and lighter.
Any shape
Straight, 45°, 90°, street 90, tee, Y, cross or a manifold with up to 8 outlets. Stainless, steel, brass, aluminum or engineering plastics.
Checked before it ships
Threads are checked with go and no-go gauges and every order ships with a certificate of conformance. Pressure test reports on request.

Can I get a BSPP to Hose barb adapter as an elbow or tee?
