Hose fitting on IMPERIAL THREADS

Hose fitting on Imperial threads are the most popular all over the world, there are a small differences between BSP and NPT sometimes even hard to guess the proper threads type and only really experienced crew is able to see the difference like for instance when you compare BSPT with NPT nyppel….

In some business field mostly NPT thread is a basic thread (oil business), thread BSP (British Standard Pipe) is really popular in Europe and Middle East or Far East, you must mention about UNF thread ( = JIC thread ) which the same like NPT thread is popular in the USA and you can say it is basic thread back there.

British Standard Pipe (BSP) – sometimes called as Whitworth’s thread, where sealing is made on METAL on METAL system (DKR-AGR), some times it is rubber sealing on the flatface ((DKRF) or sealing on the thread itself (AGR cone=BSPT).

  1. DKR – AGR – gthread BSPP (Parallel thread – sealing metal on metal DKR – AGR – sealing on 60° nest )
  2. DKR(F) – thread BSPF (Flat – Parallel thread , sealing from front side by using rubber gasket)
  3. AGR cone – thread BSPT (Tapper- cone thread where sealing is made on the thread itself) sometimes indicated as thread R eg.. R3/4″
