ARCO battery coupling Arco Złączka bateryjna łuk 1/2" x 15mm (P4563FR)

ARCO battery coupling Arco Złączka bateryjna łuk 1/2" x 15mm (P4563FR) is an angled radiator/pipe fitting designed to create a 90° connection between a 1/2" threaded valve and a 15 mm copper or plastic pipe. Intended for heating and plumbing installations, this coupling helps align radiator valves with existing pipework while maintaining a compact profile suitable for residential and light commercial systems.

Advantages

The coupling provides a reliable mechanical join that simplifies alignment between threaded radiator connections and 15 mm pipework. Its 90° angle reduces the need for additional bends or adapters, saving installation time and space. The component is compatible with common radiator valve threads and standard 15 mm pipes, offering a straightforward solution for retrofits, replacements, and new installations.

Suitable for

• Connecting 1/2" radiator valves to 15 mm supply or return pipes
• Aligning radiator outlets where a 90° change of direction is required
• Residential and small commercial heating systems
• Plumbing repairs and component replacement on existing pipework

Key specifications

• Connection: 1/2" threaded to 15 mm push or solder pipe interface
• Angle: 90° elbow
• Intended media: hot water for heating systems and general plumbing
• Application: radiator/riser connection in heating circuits
• Use environment: indoor heating and plumbing installations

How to use

Prepare the mating surfaces by ensuring the 1/2" thread on the valve is clean and free of old sealant. Cut and deburr the 15 mm pipe end to ensure a straight, clean fit. Assemble the coupling according to the valve and pipe type: for compression-style joints tighten the nut to manufacturer torque recommendations; for soldered or push-fit installations follow the relevant procedures for sealing and heat application or push-fit engagement. After installation, pressurize the system and inspect the joint for leaks before returning the system to normal operation.

Usage recommendations

Verify material compatibility between the coupling and pipe (copper, PEX, or other approved materials). Use appropriate sealing material on threaded connections where required and follow local plumbing codes. If unsure about installation method or torque settings, consult a qualified plumber to ensure a safe, leak-free connection.
