NH/NST Fire Hose Coupling
NH / NST Fire Hose Coupling (National Hose / National Standard Thread) is the official American-standard fire hose connection fitting widely adopted by fire departments, fire hose manufacturers, and fire protection distributors across North America. Designed and manufactured in full compliance with
NFPA 1963 fire safety standards, our NH/NST couplings provide stable, leak-proof, and high-pressure connection performance for all types of American fire hoses, fire nozzles, and fire pipeline systems.
We offer a complete range of standard sizes covering
1.5”, 2”, 2.5”, 3”, 4”, 4.5”, 5”, 6”, fully covering small-diameter handline fire hoses and large-diameter industrial & municipal supply fire hoses. All sizes are precisely threaded with standard NST/NH thread to ensure universal compatibility with mainstream American fire fighting equipment.
Our fire hose couplings are available in
high-grade brass and
lightweight aluminum options. Brass couplings feature excellent corrosion resistance, high pressure endurance, and long service life, ideal for professional fire department and heavy-duty industrial applications. Aluminum couplings provide lightweight, cost-effective solutions for bulk fire hose assembly and civilian fire protection projects.
Adopting the classic
pin-lug quick connection design, our NH/NST couplings allow fast installation and disassembly without extra tools, greatly improving on-site fire fighting efficiency. The precision-machined thread structure ensures tight sealing, zero water leakage, and stable performance under long-term high-pressure water flow impact.
