1" XL Bronze Male Adapter

This one-inch extra-long cast bronze adapter connects to male NPT threads for plumbing installations. It suits contractors and maintenance teams joining dissimilar pipe materials in water or gas systems. The bronze body resists corrosion in potable and non-potable applications.

Extended length for tight assemblies

The extra-long cast body provides additional thread engagement when assembling joints in confined spaces or through thick walls. Bronze construction maintains sealing integrity under sustained pressure and temperature cycling without deformation. The material withstands continuous exposure to treated water and standard fuel oils.

Replaces standard-length bronze adapters

Use this adapter when a standard coupling cannot span the gap between fixed pipe ends or fittings. The added length eliminates the need for separate nipples and couplings in retrofit work. Not for installers who require a shorter face-to-face dimension or a different thread standard.

Questions about this item

How much heat does the 1 inch XL bronze male adapter generate when installed in a hot-water line running all day?

The cast bronze construction does not generate its own heat; it simply conducts the temperature of the water passing through it.

What pipe material and thread sealant must I already have to connect this 1 inch MNPT adapter?

You need a 1 inch female NPT fitting and a thread sealant approved for potable water, such as PTFE tape or pipe dope.

Will the 312-025 adapter thread onto older galvanised or brass fittings without leaks?

Yes, the MNPT threads follow the same taper standard used on legacy galvanised and brass pipe, so they seal correctly with proper sealant.
