## Long description

ARCO battery coupling Arco Złączka bateryjna 3/4" x 22mm P4539FR is a mechanical coupling designed to connect a 3/4" threaded valve or fitting to a 22 mm copper or plastic pipe. Manufactured by ARCO, this coupling is intended for plumbing and heating systems where components with imperial and metric connections must be joined securely and with proper alignment. The compact design facilitates installations in radiators, boilers and domestic water circuits where space may be limited.
Advantages
The coupling provides a reliable mechanical transition between a 3/4" thread and a 22 mm pipe without the need for complex adapters. Its construction ensures stable alignment and a firm connection suitable for routine plumbing pressures used in residential heating and potable water systems. The straightforward geometry allows for easy access during maintenance and replacement operations.
Suitable for
Connecting radiator valves with 3/4" thread to 22 mm supply pipes
Linking boiler fittings to 22 mm distribution lines
Domestic hot and cold water installations requiring imperial-to-metric transition
Key specifications
Connection sizes: 3/4" thread to 22 mm pipe
Application area: plumbing and heating systems
Material: corrosion-resistant metal suitable for potable water and heating circuits
Design: compact mechanical coupling for inline installation
How to use
Prepare both the 3/4" threaded fitting and the 22 mm pipe by cleaning threads and pipe ends to remove debris, old sealant or oxidation. Apply an appropriate thread sealant or tape to the 3/4" thread if required by the joint type. Insert the 22 mm pipe into the coupling and align the threaded fitting; tighten to the recommended torque for the fittings involved. After installation, pressurize the system and check for leaks at the connection points, then perform any final tightening if necessary.
Usage recommendations
Use the coupling in systems operating within standard residential heating and potable water pressure ranges, and select compatible materials (copper, PEX or suitable plastic) for the 22 mm pipe. When working with heated systems, observe thermal expansion allowances and follow local plumbing codes. If in doubt about compatibility with a specific valve or fitting, consult technical documentation or a qualified installer.
