BSP / BSPT Hydraulic Fittings

BSP thread stands for British Standard Hydraulic Pipe, british hydraulic fittings is common in Australia and the commonwealth countries. British fittings are based on trade size rather than actual diameter which can lead to some confusion when measuring ports. We are british hose fitting factory in China.

There are two types of BSP threads Hydraulic Fitting;

- BSPP - Female & male thread are both (also known as G), it refers to parallel or straight threads.

- BSPT - Female thread is parallel and the male thread is tapered (also know as R/Rp) (the female thread can also be tapered, these are fairly rare to find). Within BSPT it is also common to call the female thread BSPP (parallel) and the male BSPT (tapered) even though they are both technically a BSPT thread form (the female would be parallel and the male would be tapered).

Both threads hydraulic fitting have the same pitch, angle (55 degrees) and shape (rounded peaks and valleys).
