84434997 Replacement Coupling Quick Coupler for Case IH New Holland Harvesting Equipment

84434997 is an OEM-specification hydraulic quick-connect coupling replacement part from CNH Industrial, designed specifically for Case IH and New Holland brand combines and other harvesting equipment. It enables rapid connection and disconnection of hydraulic lines, withstanding the harsh conditions of harvesting operations—dusty, damp, and vibrating environments. This significantly improves attachment changeover and maintenance efficiency while protecting hydraulic system cleanliness and component longevity. Featuring a flat-seal design, this coupling enables tool-free manual insertion and removal. It offers leak-proof, contamination-resistant, corrosion-resistant, and wear-resistant properties. As a critical wear part and common spare for harvesting equipment hydraulic systems, it ensures reliable performance under demanding conditions.
