Reducing Coupling 3/8" to 1/4" NPT

This malleable iron reducing coupling connects a 3/8 inch NPT female thread to a 1/4 inch NPT female thread. It is rated for Class 150 service and suits plumbing installations requiring a step-down in pipe size. The galvanized finish provides corrosion resistance for water, air, or gas lines.

Galvanized Malleable Iron Construction

The galvanized coating protects the malleable iron body against rust in damp or outdoor environments. Class 150 rating indicates the pressure class for standard piping systems. No additional sealant or software is bundled; the fitting relies on standard NPT thread engagement and thread tape or compound applied by the installer.

California Proposition 65 Compliance Notice

This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. Installers should follow safe handling practices and local codes. The coupling handles standard Class 150 pressure ranges but is not rated for high-pressure hydraulic or extreme temperature service beyond its class designation.

Questions about this item

How often will the galvanized coating on this malleable iron coupling need replacement?

The Class 150 malleable iron body with galvanized finish resists corrosion in standard plumbing service; inspect threads periodically and replace only if leaks or visible degradation appear.

What pressure limit appears first when this reducing coupling runs continuously?

Rated for Class 150 service, the 3/8 in to 1/4 in NPT threads hold the design pressure; sustained operation beyond that rating risks joint failure before the iron body yields.

Does the coupling generate noticeable heat or noise during all-day water flow?

As a passive galvanized malleable iron fitting with no moving parts, it adds no measurable heat or sound; fluid temperature and pump noise dominate the system.
