Fitting śrubunek grzejnikowy stożek 1/2 – radiator union cone 1/2"

Fitting śrubunek grzejnikowy stożek 1/2 – radiator union cone 1/2" is a compact mechanical fitting designed to join radiators to heating pipelines using a conical sealing surface. Manufactured by Fitting, this 1/2" union provides a threaded connection that adapts to metal or composite radiator tails and is intended for use in domestic and commercial central heating systems. The conical design ensures a secure seal under typical operating pressures of water-based heating circuits.

Advantages

The conical sealing surface delivers reliable leak resistance without the need for additional soft gaskets in many installations, while the threaded union form factor allows straightforward on-site assembly and disassembly. Its compact dimensions reduce the space required at the radiator inlet, facilitating installation in confined locations. The component is compatible with common radiator tail materials and standard 1/2" threaded heating pipework.

Suitable for

• Connecting radiators to central heating pipelines
• Replacement of existing 1/2" unions on radiators
• Renovation and new-build residential heating systems
• Commercial heating circuits with standard threaded connections

Key specifications

• Connection size: 1/2" threaded union
• Sealing type: conical (metal-to-metal) sealing surface
• Application: radiator to heating pipe connection
• Compatibility: suitable for metal and composite radiator tails
• Design: compact mechanical union for confined installation spaces

How to use

Ensure the radiator tail and mating pipe thread are clean and free of debris. Hand-start the union on the radiator tail and align the conical surfaces before tightening. Use appropriate wrenches to achieve a firm mechanical engagement without over-torquing; over-tightening may damage the conical sealing faces. If the system design or local practice requires, apply a compatible thread sealant or tape on the pipe thread prior to assembly. After installation, pressure-test the circuit according to applicable standards to verify the seal.

Usage recommendations

For reliable long-term operation, install in systems operating with clean water and follow standard commissioning procedures including flushing and chemical treatment where required. Inspect the union for leaks after initial pressurization and periodically during maintenance intervals. Replace the union if the conical sealing surfaces show signs of wear or damage.
