Hydraulic Coupler 42N-879-1430 Komatsu

The Hydraulic Coupler 42N-879-1430 Komatsu is a premium 1/2" female hydraulic quick-connect socket (NV 12 GAS F) designed for secure and efficient fluid transfer in heavy-duty construction and industrial hydraulic systems. Produced by Faster, a highly respected Italian OEM manufacturer, this coupler meets the performance, durability, and dimensional precision required for professional Komatsu machinery. Designed to handle a flow rate of up to 75 l/min at 0.2 MPa, the coupler ensures stable oil circulation with minimal pressure drop, even under continuous operating conditions. Its optimized internal valve design enables smooth coupling and uncoupling, helping to reduce turbulence, limit oil loss, and protect sensitive hydraulic components within the system. This contributes directly to improved system efficiency and longer service life. The compact yet robust construction makes this hydraulic coupler particularly suitable for confined installation areas commonly found on Komatsu equipment, auxiliary hydraulic lines, and attachment circuits. Precision-machined interfaces ensure accurate fitment and reliable locking, minimizing the risk of leakage or accidental disconnection during operation. Equipped with NBR seals, the coupler offers excellent resistance to hydraulic oils, temperature fluctuations, and mechanical wear. It operates reliably within a temperature range of -25 °C to +125 °C, maintaining sealing integrity in cold environments as well as high-temperature working conditions. This makes it well suited for construction machinery exposed to harsh climates, dust, vibration, and long duty cycles.
