Fittings
If your’e not hung up on using bronze have a look at the smaller composite glass reinforced fittings available from Trudesign and Marelon, both are rated for use below the waterline.
Trudesign make fittings in BSP or NPS straight,the distributor for them in the US is Raritan.
Another option for composite reinforced fittings is Banjo fittings,these may look like cheap PVC fittings online but thats not the case,these are are great for putting together FW flush systems and manifolds/valves.
