Hose connectors are used to connect a hose, normally to a tap connector. Hose connectors are also used to connect or join 2 pieces of hose together providing extra length or to divide a pipe in two opposite directions. Hose connectors are a quick and easy solution to connect a hose to various inlets, taps, spigots, nozzles and other hoses. Hose connectors can also be called fittings, couplings and adapters. The gender of a hose connector is important and are labelled as a male or female hose connector. You can learn more in our complete guide to hose connectors.

Hose Connector Standards and definitions.
NPT – National Pipe Thread connection.
NPT male hose connectors have a taper thread that fits into a female NPT hose connector. The male stretches the female ensuring a firm seal. An NPT male connector fits a BSPT (British Standard Pipe Thread) but does not seal.
BSPT – British Standard Pipe Thread.
A BSPT Hose Connector is similar to an NPT Hose connecter with differences. BSPT connectors have a connection angle of 55° instead of the NPT at 60°. A BSPT connector fits an NPT but does not seal.
BSPP – British Standard Parallel Pipe.
This is a parallel thread fitting that requires the use of a seal ring to complete a tight seal. The seal ring is placed between the shoulder of the male hose connector and the face of the female hose connector. The 2 connectors squeeze together on the hose forming a tight seal.
