Nipple, 1 1/2" BSPT x 1 1/2" NPT Brass Nipple
I had a lot of difficulty finding a good quality adaptor to go from BSP to NPT threads so, we make these units specifically for Irrigation Warehouse Group. If you need to adapt a thread from NPT to BSP or the other way around, these brass units are just the ticket. Supplied as a 1 1/2" male BSPT thread on one end and a 1 1/2" male NPT thread on the other end. Made in Australia! 25-YEAR WARRANTY.
