CB-3 Brass Quick Coupling for Hydraulic & Pneumatic Systems | High-Pressure Compatible
The CB-3 Series Medium-Pressure Brass Quick Coupling delivers reliable performance for hydraulic, pneumatic, and industrial fluid transfer. Constructed with corrosion-resistant brass, zinc-plated steel, or stainless steel, it withstands harsh environments.
Key features include auto-sealing poppet valves to prevent leakage when uncoupled, hardened components for extended durability, and compatibility with hydraulic fluids, chemicals, water, steam, and gases. Customizable seals (NBR, Viton, EPDM) ensure resistance to extreme temperatures and aggressive media. Directly interchangeable with PARKER 60, FASTER HNV, AEROQUIP FD45, and HANSEN HK series, enabling seamless integration into existing systems. Ideal for industrial machinery, agricultural equipment, and construction applications requiring leak-free, high-flow connections. Engineered to minimize downtime and maximize efficiency in medium-pressure B2B operations.
