  • Connects 2-1/2 inch NST female to 1-1/2 inch NPT male

  • Rigid straight shape maintains alignment under pressure
  • Sandblast finish provides clean surface for reliable sealing

Brass fire-hose adapter for NST-to-NPT connections

This straight rigid fitting joins a 2-1/2 in female NST hose coupling to a 1-1/2 in male NPT pipe thread. It is built for fire-protection and industrial water systems where a secure pin-lug connection is required. The sandblast brass finish resists corrosion in wet environments.

Verify thread standards

Confirm that the existing hose uses NST threads and the pipe or valve uses NPT threads, as the two standards are not interchangeable. Ensure the pin-lug tightening method matches the lugs on your hose coupling and that the rigid straight shape suits the installation layout. The fitting contains chemicals listed under California Proposition 65.

Sandblast brass body with pin-lug tightening

The all-brass construction provides durability and resistance to galvanic corrosion in fire-suppression service. Pin-lug tightening allows rapid hand connection without tools during emergency deployment. The rigid straight profile keeps the hose alignment fixed, reducing stress on the connected pipework during pressure surges.
