Based on the different thread type, we divided threaded cap into NPT cap and BSP cap

NPT Cap

NPT refers to national pipe threaded which is conform to American standard ASME B1.20.1. NPT cap has tapered thread with 60 degree thread angle, its seal requires 2 turns of sealant.

BSP Cap

BSP threaded cap are British standard threaded fittings and can be further divided into BSPP cap and BSPT cap.

BSPP Cap is parallel threaded fittings and uses bonded seal rings to do the sealing. This type threaded fittings are most popular in the UK, Asia, South Africa and Europe.

BSPT cap is similar to NPT thread fittings that has tapered thread, but it thread angle is 55 degree which is different with NPT thread. Even through they are tapered thread, NPT threaded fittings cannot be connected with BSPT threaded fittings.
