6" x 4" Galvanised Hex Bushing

The Legend Valve 352-658 is a galvanised hex bushing designed to connect a 6-inch female NPT fitting to a 4-inch male NPT fitting. It is intended for plumbers and maintenance engineers joining dissimilar pipe sizes in water, oil or gas distribution systems where galvanised steel is specified.

Galvanised coating and hex profile

The hot-dip galvanised finish provides a sacrificial zinc layer that resists corrosion in exposed or damp installations, extending service life compared to bare steel. The external hex flats allow a standard pipe wrench to apply high torque during assembly without rounding the fitting, reducing the risk of leaks at the joint.

Thread compatibility requirement

This fitting only works when the system uses 6-inch FNPT and 4-inch MNPT threads; it cannot join metric, BSP or any other thread standard. Installers must verify both pipe ends match these exact NPT sizes before purchase.

Questions about this item

Will the galvanised coating on this 6-inch by 4-inch hex bushing need replacement or recoating over time?

The galvanised finish protects the steel from corrosion; under normal plumbing conditions it lasts the service life of the fitting without scheduled maintenance.

What pressure or temperature limit will be reached first during continuous service?

The bushing follows standard SA galvanised NPT ratings; the pressure class of the connected piping typically governs the maximum sustained pressure.

Does the fitting generate noticeable heat or noise when water flows through it all day?

As a passive thread adapter it adds no mechanical noise or heat; any sound or temperature rise comes from the fluid and pump, not the bushing itself.
