The H401 Series hydraulic quick couplings are engineered for demanding industrial applications in construction equipment, forestry machinery, and hydraulic systems. These high-performance couplings ensure reliable fluid transfer under extreme working conditions.
Key features include poppet valves that automatically prevent uncoupled leakage while maintaining smooth flow when connected. The critical components undergo special hardening treatment to enhance durability and service life. These couplings are fully compatible with Nitto HSPCUPLA series components.
The standard fluororubber seals perform reliably in temperature ranges from -20°C to +80°C. Available in multiple sizes from 1/4" to 1", these couplings support various pressure ratings up to 5000 PSI depending on size.
Manufactured with precision engineering, these quick couplings feature zinc-plated surfaces for corrosion resistance and are available in carbon steel or stainless steel materials. The ball locking connection method ensures secure attachment during operation.
