National Pipe Straight Mechanical (NPSM) fittings are used to connect pipes valves joints and pressure sensors. They are swivel fittings with a straight thread and a 30° cone that create a mechanical seal with male NPTF fittings. NPSM threads are also used in mechanical engineering and pneumatic systems Crimp Couplings compatible with 100R1AT 100R2AT 1SN 2SN R16 R17 100R3 & 100R4 Hoses - Trivalent Zinc Plating

• • Reducing hose stress: NPSM fittings are designed to reduce stress on hoses that can occur when twisting them during assembly. • Reducing the number of fittings needed: NPSM fittings can help reduce the number of hose fittings required. • Creating a mechanical seal: NPSM fittings create a mechanical seal when paired with NPTF male fittings. • Facilitating installation: The swivel connection on NPSM fittings makes them easy to install on hydraulic applications. • Connecting pipes valves and pressure sensors: NPSM threads are used to connect pipes valves joints and pressure sensors. • Optimizing heat transfer: When used with a thermometer that has an NPT male thread NPSM female threads can optimize heat transfer
