The COILHOSE PNEUMATICS 2004 is a brass pneumatic hose coupling designed for use in compressed air systems requiring a Rectus Type 20 interchange connection. The body measures 7/64 inches in diameter and accepts hose with a 5/32-inch inside diameter via a hose barb thread type. A nickel finish provides corrosion resistance in demanding shop environments. Rated to 500 psi maximum working pressure, this connector handles the pressure ranges common in industrial and commercial pneumatic lines. Licensed HVAC technicians, plumbers, and general mechanical contractors working with pneumatic tool and control systems will find this a straightforward drop-in coupling.
This coupling is suited for light-duty to medium-duty pneumatic applications in residential and commercial settings. Typical use cases include connecting pneumatic control tubing, air tool lines, and compressed air distribution systems where Rectus Type 20 interchange fittings are specified. The hose barb end accepts 5/32-inch ID hose directly, making installation fast without additional adapters. Its compact size makes it practical in tight plumbing and mechanical rooms where space is limited.
Designed as an OEM-style connector for compressed air and pneumatic control systems using Rectus Type 20 interchange fittings with 5/32-inch ID hose barb connections.
Installation is typically performed by a mechanical or pneumatic system technician. Depressurize the air line fully before removing or installing any coupling. Ensure the hose barb is fully seated and secured with an appropriate clamp rated for the operating pressure. Follow applicable OSHA compressed air safety guidelines and any local mechanical codes governing pneumatic system assembly.
