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.
