Cast Steel Cone Double Coupling 1/2″ ODLEWNIA model 54, zinc-plated, weight 0.242 kg

Cast Steel Cone Double Coupling ODLEWNIA model 54 is a 1/2" nominal-size, zinc-plated conical coupling designed to join two threaded fittings or hose connections with a cone-to-cone seal. Manufactured from cast steel and finished with zinc plating, this double-socket conical coupling provides mechanical strength and surface protection against corrosion. The coupling has a compact profile and a mass of approximately 0.242 kg, suitable for plumbing and industrial fluid systems where a conical sealing interface is required.

Advantages

The coupling combines the mechanical durability of cast steel with a zinc-plated surface for improved corrosion resistance in damp or mildly corrosive environments. Its conical double-socket design allows for tight cone-to-cone sealing without the need for additional sealing elements in many installations, and the 1/2" nominal size fits common threaded fittings and hoses. The part’s simple geometry and robust construction enable reliable mechanical connection and ease of assembly and disassembly during maintenance.

Suitable for

• Plumbing systems requiring conical threaded connections
• Industrial fluid lines with 1/2" fittings or hoses
• Repair and replacement of worn or damaged conical couplings
• Applications where a mechanically strong, corrosion-resistant coupling is needed

Key specifications

• Material: cast steel
• Surface finish: zinc-plated
• Nominal size: 1/2"
• Design: double cone (two-socket conical) coupling
• Mass: 0.242 kg (approx.)
• Connection type: threaded cone-to-cone interface

How to use

Select matching threaded fittings or hoses with a 1/2" nominal size and compatible conical seat geometry. Ensure threads and cone faces are clean and free of debris. Thread the mating parts into each socket of the double coupling by hand until snug, then tighten with appropriate tools to the torque recommended for the specific fittings in use. Inspect the cone-to-cone contact for uniform seating; if required by the application, use an appropriate thread sealant compatible with the fluid and materials involved. After installation, test the assembly under working pressure to verify there are no leaks.

Usage recommendations

Use the coupling in systems where moderate corrosion resistance is sufficient; avoid prolonged exposure to highly corrosive chemicals or sea water without additional protective measures. Regularly inspect threaded connections for wear or damage, and replace the coupling if cone seats become deformed or pitted to maintain a reliable seal.
