Kitchen Sink Or Bath Waste Trap 1 1/12 to 40 or 50mm

Kitchen sink Or Bath Waste Trap 1 1/12 to 40 or 50mm (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”)
Example – 1 1/2 (6/4″) Plastic nut with rubber seal at one end for connection to items such as bath waste connection or Kitchen sink. 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.
**(+/- some small acceptable tolerance)
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.
A list of 16 thread sizes are defined by the standards, ranging from 1?16 Inch to 6 Inch. The size was originally based on the inner diameter measured in inches of a steel tube for which the thread was intended. This often causes confusion, as people think the size refers to the outside diameter of the male thread.
