Check your pipe threads before you order!

In Great Britain BSP  British Standard Pipe threads are commonly used. These are either parallel (BSPP ) which normally seal on a washer or 'O' ring seal, or tapered (BSPT)  which taper along their length and normally seal by two mating threads and/ or tape.

How to measure your thread:

Use a tape rule or (vernier gauge) to measure across the outside of the male thread. Note that a thread that measures 0.5" is not 1/2" BSP thread!

Using the table below we can see that  0.5" is actually 1/4" BSP thread . Similarly, a thread that measures  1.0" is actually 3/4" BSP thread .
