- Galvanized malleable iron resists corrosion for long service life
- FNPT threads create a secure seal on 1-1/2" to 1/2" pipe transitions
- Rated 300 psi at 150 °F WOG for reliable pressure handling
- Meets ASME B16.3, B16.4, ASTM A197, A47, FM, NSF-61, AB1953 and UL standards
- California Proposition 65 warning: contains chemicals known to cause cancer and reproductive harm
Galvanized Reducer Coupling 1-1/2" x 1/2
This galvanized malleable iron reducer coupling connects pipes of different diameters using female NPT threads on both ends. It meets ASME B16.3 and B16.4 standards plus ASTM A197 and A47 specifications. The fitting carries FM approval and NSF-61 certification for drinking water contact. It is suitable for residential and commercial plumbing installations.
Class 150 Pressure Rating 300 PSI WOG
Rated for 300 psi water, oil, and gas at 150 degrees Fahrenheit, the coupling handles typical supply-line pressures with margin. Saturated steam service is rated at 150 psi, limiting use in high-temperature steam loops. The Class 150 schedule provides adequate wall thickness for standard municipal and well-water systems. Installers should verify system pressure against these limits before assembly.
Lead-Free Compliance AB1953 Listed
The galvanized coating resists corrosion in potable water applications while the AB1953 listing confirms lead-free status for safe drinking water use. California Proposition 65 warnings apply due to chemical content in the material. No external power or moving parts means silent operation and zero energy draw. Routine inspection ensures thread integrity over the service life.

Questions about this item
Will the 1-1/2" FNPT threads mate cleanly with my existing galvanized pipe nipples?
The coupling uses FNPT threads on both ends to ASME B 16.3 dimensions, so standard galvanized nipples will engage fully without cross-threading.
How can I verify the joint is leak-free at the rated pressure after installation?
Pressurise the line to 300 psi WOG at 150 °F; no weeping at the threads or body confirms the Class 150 malleable-iron casting is sealing correctly.
Does the box include thread sealant or do I need to buy pipe dope separately?
Only the yellow zinc-coated reducer coupling is supplied; PTFE tape or pipe compound must be purchased separately for the FNPT joints.
