ARCO battery connector fitting Arco Złączka bateryjna łuk 1/2" x 22mm P4566FR

ARCO Arco Złączka bateryjna łuk 1/2" x 22mm P4566FR is an angled battery connector fitting designed for central heating and radiator installations. It provides a 90° connection between a 1/2" threaded valve and a 22mm copper or multilayer pipe, enabling a compact and mechanically secure junction in confined spaces. The elbow geometry reduces stress on pipe runs and facilitates neat installation behind radiators or in tight utility areas.

Advantages

The fitting delivers a reliable mechanical and hydraulic connection suitable for domestic and commercial heating systems. Its angled design allows installation where straight fittings would not fit, improving accessibility and reducing the need for additional pipe bends. Constructed to match standard valve and pipe dimensions, the connector supports straightforward assembly and long-term performance when installed according to system requirements.

Suitable for

• Connecting radiator valves with 1/2" threads to 22mm heating pipes
• Compact installations behind radiators or in confined service cupboards
• Retrofit and repair work on central heating systems
• Domestic and light-commercial hydronic heating circuits

Key specifications

• Connection 1: 1/2" threaded valve connection
• Connection 2: 22mm push-fit or compression pipe connection
• Angle: 90° elbow configuration for space-saving layout
• Application: hydronic heating and radiator plumbing
• Compatible with copper and multilayer (PEX/Al/PEX) heating pipes where appropriate

How to use

Prepare the pipe and valve threads according to manufacturer recommendations, ensuring clean, deburred pipe ends and correct thread sealing where required. Position the elbow fitting so the 1/2" threaded side engages the radiator valve and the 22mm side connects to the prepared pipe. Tighten connections to the torque values recommended for the valve and fitting types, and check the assembly for alignment. After installation, pressure-test the circuit to verify there are no leaks and that the hydraulic seal is intact.

Usage recommendations

Use with compatible radiator valves and appropriately rated heating pipes. Verify material compatibility and follow local plumbing codes. For permanent installations, perform a pressure test and inspect joints periodically. If uncertain about installation or torque values, consult a qualified heating engineer.
