BSPP and NPT threads don't play well together — they look similar but are cut at different angles and won't seal without an adapter made for the job. This brass fitting bridges a G 1/2" male (BSPP) thread to a 3/4" NPT male thread, giving you a secure, leak-free connection between the two standards without improvising with tape or forcing incompatible fittings. Lead-free construction and a lifetime warranty back it for residential and commercial installations.

What It Does

Connects a G 1/2" male thread — common on European and Asian plumbing fixtures, shower valves, and Cascada products — to a 3/4" NPT male fitting standard in US residential and commercial plumbing. Precision-machined threads seat cleanly and hold at pressures up to 230 psi across a temperature range from deep cold to hot water service. No sealant gimmicks required — just proper thread engagement and standard PTFE tape on the NPT side.

Corrosion Resistance and Lead-Free Compliance

Brass resists the mineral deposits and chemical exposure that corrode cheaper zinc or plastic adapters over time. Lead-free construction meets safe drinking water standards for potable water lines — no restriction on where this fitting can be used in residential plumbing.

Who Uses This

Plumbers and contractors connecting imported or European-spec fixtures — shower valves, handheld shower arms, faucets — to US standard supply lines. Also used by homeowners installing Cascada shower systems that ship with G 1/2" connections onto existing 3/4" NPT supply infrastructure.
