To find the thread size: 1) Measure the O.D (Outer diameter) of the BSP thread. 2) Take the O.D measurement in inches and subtract 1/4 (.25″). For example, a BSP parallel male thread measures out to O.D 1″. Subtracting 1/4 gives a thread size of 3/4 also known as "dash" 12.

British Standard Pipe fittings are among the most popular of all foreign threads in the world today. These threads come in two versions: parallel (BSPP), 

G/R/RP - Withworth thread (BSPP/BSPT) ; R 1/8, Rp 1/8, 9,728 ; R 1/4, Rp 1/4, 13,157 ; R 3/8, Rp 3/8, 16,662 ; R 1/2, Rp 1/2, 20,955 

These threads come in two versions: parallel (BSPP), and tapered (BSPT). The thread 1) Measure the O.D (outer diameter) of the BSP thread.

BSP threads have a 55° included angle and have rounded peaks and valleys (this is a Whitworth thread form). Here are the actual thread dimension data for BSPP and BSPT threads. The major diameter is a bit larger smaller than the actual OD of the pipe, and the minor diameter should be very close to what you would measure inside the

BSPP Fittings Thread conforms to ISO 228-1, The port complies with ISO 1179, Pitch and diameter measured in inches, e.g. Ex. G1 / 4-19, Parallel threads require an O-ring, lock washer, gasket, or metal-to-metal seal between the connections for a tight connection, The angle of the thread is 55 °, Not interchangeable with SAE or NPT (F)

BSPP ( British Standard Pipe Parallel) taps produce a straight whitworth (55 degree) thread in standard sizes from 1/16 to 6 somewhat related to the inside diameter of pipe. What do these icons mean? Product Options & Sizes Distributors Order Online Test This Tool

of BSPP adapters, most all males in series "B" can be used for as a Port Connection with the addition of a bonded seal. Measurement Procedure 1. With calipers, measure the O.D. (outer diameter) of the Male threads or the I.D. (inner diameter) of the threads. 2. Check the thread pitch with the thread pitch gauges. 3.

National Pipe Thread (NPT) is a family of technical standards for threads that has been adopted internationally for interconnecting hoses and fittings by mating an external (male) thread with an internal ( ) thread. National Pipe Threads are similar in function to BSP threads, but are not generally interchangeable.
