BSP (British Standard Pipe) threads can be parallel or tapered. Tapered threads are for permanent connection only and are considered 'not hygienic'. Parallel threads are hygenic, threads must be sealed with ptfe tape for permanent connection (for example valves), or will be fitted with a rubber seal if the fittings are to be removed regularly (for example hose-connectors).

RJT (Rubber Joint Thread), sometimes known British Standard Milk thread. Still used widely in breweries.

The union consists of a hexagon nut in AISI-304 stainless steel, a weld-male-thread part and a pressed liner both in AISI-316; the liner is pressed from 1.5 mm thick sheet.
A pressed blank cap can be used, in place of the normal liner, to make a blank-off fitting.
The rubber joint ring is an "O" type (6.6 mm diameter) and is normally made of Nitrile rubber.
