Brass Fire-Hose Adapter

The Value Brand pin-lug coupling joins a 2-1/2-inch female NST thread to a 1-1/2-inch male NPSH thread. Fire-service teams and industrial maintenance crews use it to connect dissimilar hose or hydrant fittings without tools.

Rigid Brass Construction

Sand-blasted brass resists corrosion and deformation under pressure. Pin-lug tightening lets operators secure the joint by hand, while the straight, rigid body keeps alignment fixed during flow.

Thermal and Flow Behaviour

Brass conducts heat away from the water stream, so the fitting stays near ambient temperature in normal service. No moving parts or seals generate noise, and the rigid design adds no measurable flow restriction.

Questions about this item

What does the NST x NPSH thread standard limit this adapter to?

The adapter connects a 2-1/2 inch female NST hose thread to a 1-1/2 inch male NPSH straight pipe thread, so it only mates with matching fire-hose and plumbing threads.

What clearance and pipe size must the installation allow for?

The rigid brass body needs space for the 2-1/2 inch female NST end and the 1-1/2 inch male NPSH end, and the pipe side must accept a 1-1/2 inch NPSH connection.

How is the pin-lug coupling tightened and what step is often missed?

The pin lugs are turned by hand or with a spanner wrench to engage the female NST swivel; the step often missed is ensuring the internal gasket seats fully before tightening to prevent leaks.
