diameter (male spigot)(“Quoted In Internationally adopted B.S.P.T. British Standard Pipe Thread – Actual outside thread diameter is approx 1.882 or 47.80 mm”)
For example – 1 1/2 (6/4″) Plastic nut with rubber seal at one end for connection to items such as bath waste connection. Other end connected to 40 or 50 mm female *Pushfit / *Solvent / Compression connector
*(Diameter’s quoted (32,40 & 50mm) are actual sizes**. Some other suppliers use slightly smaller or larger fittings but may still refer to them as 32,40 or 50 mm so it is recommended that to be certain your fittings are compatible you measure the internal diameter of your fittings to ensure a suitable seal / Fitting will be achieved.
*(Some solvent pipes use a larger pipe diameter so measure your pipe and fittings diameters to ensure correct sizing is used. Ours is quoted in actual sizes** i.e 40 mm is 40 mm. Also note sometimes the addition of extra glue can resolve small tolerance differences.
British Standard Pipe Thread is a family of standard screw thread types that has been adopted internationally for interconnecting and sealing pipe ends by mating an external (male) with an internal (female) thread.
