Hydraulic Coupler 42N-879-1280 Komatsu

The Hydraulic Coupler 42N-879-1280 Komatsu is a precision-engineered 1/2" female hydraulic quick-connect socket (NV 12 GAS F), developed to ensure safe, efficient, and repeatable fluid connection in heavy-duty construction and industrial hydraulic systems. Manufactured by Faster, a well-established Italian OEM brand widely trusted by leading equipment manufacturers, this coupler meets the reliability standards expected in Komatsu hydraulic applications. Designed to deliver a flow capacity of up to 75 l/min at 0.2 MPa, the coupler supports stable hydraulic performance while limiting pressure loss during operation. Its optimized internal valve structure enables smooth engagement and disengagement, helping to reduce flow turbulence, prevent oil spillage, and protect downstream hydraulic components from unnecessary stress. The robust yet compact body construction makes this coupler particularly suitable for Komatsu machines where installation space is limited and system accessibility is critical. Precision-machined interfaces ensure consistent alignment and secure locking, minimizing the risk of leakage or accidental decoupling under vibration or dynamic load conditions. Fitted with high-quality NBR seals, the coupler provides strong resistance to hydraulic fluids, temperature variation, and everyday mechanical wear. With a working temperature range of -25 °C to +125 °C, it maintains sealing performance and functional reliability in both cold-start conditions and high-temperature operating environments. This makes it well suited for Komatsu equipment operating across construction sites, earthmoving operations, and demanding duty cycles. As an OEM-grade hydraulic connection component, the Hydraulic Coupler 42N-879-1280 Komatsu offers dependable performance, long service life, and compatibility with professional hydraulic systems where operational safety and durability are non-negotiable.
