Brass NST-to-NPT fire-hose adapter

This straight adapter connects a 2-1/2 in female NST hose thread to a 2 in male NPT pipe thread. The body is machined from brass with a sandblast finish and uses a rigid pin-lug tightening method. It is supplied new and intended for fire-suppression and industrial water-transfer assemblies.

Suits crews joining NST hose to NPT piping

Installers who need a direct, rigid transition between these two thread standards will find the fitting matches the specified sizes. Teams requiring a swivel joint, a different thread combination, or a non-brass alloy should select another part.

Rigid brass holds alignment under pressure

The fixed geometry keeps the hose and pipe axes locked together during sustained flow, and the pin-lug nuts resist loosening from vibration. Brass construction withstands continuous water exposure without the degradation seen in softer metals.

Questions about this item

What size NPT male pipe thread must I already have for the 2 in NPT male end to connect?

The adapter’s B side is a 2 in NPT male thread, so the pipe or fitting you join it to needs a matching 2 in NPT female thread.

Will the 2-1/2 in NST female swivel work with my existing 2-1/2 in NST male hose coupling?

Yes, the A side is a 2-1/2 in NST female pin-lug swivel that threads onto a standard 2-1/2 in NST male hose coupling.

How can I verify the joint is sealed after tightening the pin lugs?

Pressurize the line and check for leaks at both the NST swivel and the NPT male threads; a properly tightened pin-lug connection should show no water escape.
