FAQ:

Q: What size is a BSP thread?

A: For example a 1/2″ BSP thread (see above) actually measures more like 3/4″ with a ruler. The size was originally based on the inside diameter, measured in inches, of a steel pipe for which the thread was intended. This is the source of the confusion, as people think the size refers to the outside diameter of the male thread.

Q: What does BSP mean in pipe size?

A: British Standard Pipe Thread. For example a 3/4 inch BSP thread actually measures more like 1 inch with a ruler. 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.

Q: What size BSP do I Need?

A: 3/8 Inch BSP – Central heating oil line connectors, some European toilet cistern fill valves (not common in UK). 1/2 Inch BSP – Bathroom basin taps and kitchen sink taps, radiator connections, shower hoses, old outside tap outlets, toilet cistern fill / float valves. 5/8 Inch BSP – Old outside tap outlets (we have an adaptor for this size).
