NIBCO 775-LF 2-1/2 in Bronze Flange
This NIBCO 775-LF is a Class 150 threaded companion flange made from bronze for potable water systems. It connects a 2-1/2 in FNPT pipe to a flanged joint using four bolt holes on a 7 in outside diameter. The fitting meets ASME B16.18, NSF/ANSI 61 and NSF/ANSI 372 standards. It is rated for 269 psi at 200 Degrees F.
Suits installers joining threaded pipe to flanged
This flange suits plumbers and maintenance teams adapting 2-1/2 in FNPT pipework to a bolted flange connection in potable water service. It is not for systems exceeding the 269 psi or 200 Degrees F limits. Buyers needing a different pipe size, a sweat or press connection, or a higher pressure class should look at other fittings.
Class 150 pressure rating at 269 psi
The single specification that decides fit is the Class 150 rating with a 269 psi maximum operating pressure at 200 Degrees F. Verify your system design pressure and temperature against these limits before selecting this bronze flange.

Questions about this item
Will the bronze flange need periodic gasket replacement under normal service?
The Class 150 threaded companion flange uses a flat gasket between the 7 in flange face and the mating pipe; bronze does not corrode in potable water, so only the gasket itself wears and should be inspected during routine system shutdowns.
At 269 psi and 200 °F continuous duty, which rating is reached first?
The 200 °F maximum operating temperature is the limiting factor; pressure capacity drops as temperature rises, so sustained exposure near 200 °F will govern design life before the 269 psi ceiling is tested.
How much heat does the fitting radiate when hot water circulates all day?
Bronze conducts heat efficiently, so the 2 1/2 in body and 7 in flange will approach fluid temperature; insulation jackets are typically added to reduce surface heat loss and protect nearby personnel.
