BSPP TO BSPP Adapters
BSPP To BSPP Adapters of each end are a composite material that uses a sealing ring for sealing. This mating seal ring is pressed over the shoulder of the male fit and the face of the female fit and pressed into place.
The BSPP pressure gauge has a longer sleeve and uses a copper washer that presses the bottom of the male fitting and the bottom of the BSPP female hole to create a seal. No thread sealant is required to create the seal.
The type of BSPP To BSPP Connection
Two types of fittings, BSP (British Standard Pipe) and BSPT (Conical), are similar to NPT fittings, but most of the sizes have different threads and the outside and outside diameter materials and threads are similar, but not the same. Sealing is caused by the deformation of the threads. For this reason, it is recommended to use UK thread sealants when attaching these types of connections.
BSPP (parallel) male connections are similar to NPSM males, except the sizes have different wires. Captive gaskets consist of a metal-to-metal slanted surface or a combination of metal-to-metal gaskets and O-rings. This type of interaction is similar to the men in the US NPSM but is less variable. The BSPP female swivel has a tapered, non-flare swivel end cap that seals into the tapered seat of the male connector.
Note: Larger threads usually indicate a smaller size first with the letter “G” or “R”. Where “G” stands for parallel threads and “R” stands for tapered threads. For example, BSPT 5 / 8-14 can receive R 5/8 and BSP 1 / 16-28 can receive G1 / 16.
