Threaded Fittings

Threads to ISO 7/1 and ISO 228/1

In «ISO 7/1» the internal thread is parallel and the external is tapered. When these items are tightened, a sealing is formed on about one and a

half turns (see type A). (ISO 7/1 corresponds BSP standard = British Standard Pipe Thread)

In «ISO 228/1» both internal and external threads are parallel. This connection does not seal (see type B).
