3-1/2" x 3" Galvanized Hex Bushing

This galvanised hex bushing reduces a 3-1/2 inch female NPT thread to a 3 inch male NPT thread. It is intended for plumbing professionals and maintenance teams who need to join mismatched pipe sizes in water or gas distribution systems. The fitting is supplied new and ready for installation.

Hex profile and galvanised coating

The external hex flats allow a standard wrench to apply torque without rounding the fitting. Galvanising adds a zinc layer that resists corrosion on exposed threads, extending service life in damp or outdoor environments. No additional sealant or software is included in the package.

Threaded connections and compliance note

FNPT and MNPT threads create a tapered seal that tightens under pressure, reducing the chance of leaks during daily operation. The product carries a California Proposition 65 warning for chemicals linked to cancer and reproductive harm, so installers should follow local safety practices when handling and disposing of the fitting.

Questions about this item

Will the galvanized coating on the 352-644 bushing need replacement or maintenance over time?

The galvanized finish protects the steel threads from corrosion in normal plumbing service; no scheduled maintenance is required, though inspection during system checks is good practice.

What pressure or temperature limit will the 352-644 hex bushing reach first under continuous operation?

As a SA galvanized hex bushing with FNPT/MNPT threads, its practical limit is the pressure rating of the piping system it joins; the fitting itself has no separate published rating.

Does the 352-644 bushing generate noticeable heat or noise when water runs through it all day?

The fitting is a passive threaded connector with no moving parts, so it produces no operational noise and negligible heat beyond the fluid temperature.
