Dixon FMG-UBS-15 1/2" Screwed Union Female x Female BSP Galvanised Malleable Iron
Available
This Dixon screwed union has female BSP threads at both ends and joins two male-threaded pipes or fittings. Because it is a union, the line can be opened up again without turning the pipework. It is galvanised malleable iron, and this page lists 9 sizes from 1/2" to 4".
Dixon describes its galvanised malleable iron BSP fittings as ISO 5922 malleable cast iron, hot dip galvanised to ISO 1461, with ISO 7-1 pipe threads, for general low-pressure air and water at a working pressure of 150 PSI (about 10 bar) (manufacturer-stated). The same union is also listed by Dixon in 316 stainless steel (SS16FU series), and the table shows the matching part number for each size (manufacturer-stated).

Selecting the right option
A union is the right fitting where you will need to take the line apart later; a socket joins two pipes permanently. Both ends are female, so each side needs a male BSP thread. BSP threads do not mate with NPT or metric threads, so confirm the thread on every mating part before you order.
