SKU CH-SH9Q-N508Y

A brass pin-lug adapter connects a 2-1/2 in NST female hose to a 2 in NPSH male fitting with a rigid straight design

  • Connects 2-1/2 in NST female to 2 in NPSH male
  • Pin lug tightening allows quick hand assembly without tools
  • Brass construction resists corrosion in fire hose service
  • Rigid straight form maintains alignment under pressure
  • Sandblast finish provides consistent surface for reliable sealing

Brass Pin Lug Coupling

This brass pin lug coupling connects a 2-1/2 inch female NST thread to a 2 inch male NPSH thread. The rigid straight fitting is designed for fire hose adapter applications where a secure pin lug connection is required.

Flow Capacity and Pressure Limits

The 2 inch male NPSH end determines the maximum flow passage through the coupling. It handles standard fire hose pressures but will restrict flow if the system demands a full 2-1/2 inch bore throughout.

Female NST to Male NPSH Threads

The specific thread combination of female NST on one side and male NPSH on the other decides compatibility. Verify both thread standards on your existing hose and equipment before purchasing.

Questions about this item

Will the 2-1/2 in NST female end fit the fire hose coupling I already use?

The fitting has a 2-1/2 in NST female connection and a 2 in NPSH male connection, so it matches standard fire hose threads of those sizes.

How can I confirm the pin lug coupling is sealing correctly after installation?

Pressurise the line and check for leaks at both the NST and NPSH threads; the rigid brass body and sandblast finish should hold pressure without weeping.

Does the box include any gaskets or thread sealant for the NST and NPSH connections?

The supplier lists nothing included, so you will need to supply the appropriate gaskets or sealant for both thread types yourself.
