Zoro Select Hex Bushing 2-1/2" x 1

The Zoro Select hex bushing connects a 2-1/2 inch female NPT thread to a 1 inch female NPT thread. Malleable iron construction provides mechanical strength for plumbing installations. The fitting carries a Class 150 rating for standard pressure service.

Installers joining dissimilar pipe diameters

This bushing suits installers who need to reduce a 2-1/2 inch female port to accept a 1 inch male pipe thread. It is not intended for applications that require a male-to-male connection or a different thread standard such as BSPT. Buyers needing a larger reduction step or a different material should select another fitting.

Class 150 malleable iron rating

The Class 150 designation defines the pressure-temperature envelope for the malleable iron body. This single specification determines whether the bushing meets the system design pressure. Verify the rating against your piping schedule before installation.

Questions about this item

Will the malleable iron threads need sealant replacement over time?

Standard NPT threads on this Class 150 bushing rely on thread sealant or tape; reapply whenever the joint is broken and remade to maintain a leak-free seal.

What pressure limit governs continuous service for this Class 150 fitting?

The Class 150 rating defines the maximum non-shock working pressure for the malleable iron body at ambient temperature; do not exceed that limit in sustained use.

Does the iron body radiate noticeable heat when hot water circulates all day?

Malleable iron conducts heat from the fluid, so the bushing will reach water temperature; insulate the pipe run if surface heat is a concern.
