Steel Large Flow Application in Pneumatic tools,automotive,compressed air,shipbuilding Pneumatic Quick Couplings
The Air Quick Release Connector Coupling is a heavy-duty industrial solution designed for high-performance pneumatic systems. Constructed from chrome-plated carbon steel, it ensures superior corrosion resistance and durability in demanding environments. Available in 1/8", 1/4", 3/8", and 1/2" sizes, it supports BSPP, G, and NPT threads, guaranteeing seamless integration with global piping standards. Rated for 1.0 MPa, it reliably handles compressed air systems in automotive, shipbuilding, and industrial machinery applications.
Engineered for cross-compatibility, this coupler seamlessly interfaces with Nitto Hi-cupla, Cejn 315, and Rectus 13KA series, minimizing downtime during tool changes. Its ergonomic quick-release design enables rapid connection/disconnection, optimizing workflow efficiency. Ideal for pneumatic tools, compressed air lines, and hydraulic equipment, the coupling combines rugged construction with universal adaptability, meeting stringent industrial safety and performance requirements.
