3-Inch Galvanized Street Elbow

This 3-inch galvanized malleable iron street elbow connects a female NPT thread to a male NPT thread at a 45-degree angle. It is rated for 300 psi at 150 degrees Fahrenheit WOG and 150 psi saturated steam pressure. The fitting meets ASTM A-197, ASTM A47, ASME B16.3 and B16.4 standards for Class 150 service.

UL FM NSF-61 AB1953 Certifications

The UL listing and FM approval confirm compliance with recognized safety and performance benchmarks for plumbing components. NSF-61 and AB1953 listings verify the fitting meets low-lead requirements for potable water systems. California Proposition 65 warnings indicate the product contains chemicals identified by the state as causing cancer and reproductive harm.

NPT Thread Compatibility Limits

The FNPT by MNPT connection requires matching National Pipe Taper threads on both mating components to seal properly. The 45-degree fixed angle cannot be adjusted after installation and may restrict flow compared to a straight coupling. Galvanized malleable iron is not recommended for use with certain aggressive chemicals or in applications requiring stainless steel corrosion resistance.

Questions about this item

Will the galvanized malleable iron on this 3 inch FNPT x MNPT street elbow need replacement due to corrosion over time?

The galvanized coating protects the malleable iron body. Under normal water service at Class 150 pressure, the fitting is designed for long-term use without scheduled replacement.

What pressure limit will this 45 degree street elbow reach first during continuous operation at 150 degrees F?

The 300 psi WOG rating at 150 degrees F is the primary limit. For saturated steam service the lower 150 psi rating applies instead.

Does this galvanized street elbow generate heat or noise when water flows through it all day?

As a passive fitting with no moving parts it produces no noise or heat of its own. Fluid temperature and pump noise are determined by the rest of the system.
