ARCO battery connector 1/2" x 15 mm P4531FR

ARCO battery connector 1/2" x 15 mm P4531FR is a mechanical transition fitting designed to join a 1/2-inch thread or tubing to a 15 mm pipe. Manufactured by ARCO, this compact connector enables a secure, straightforward adaptation between imperial and metric plumbing or battery line sections where such a size change is required. It is intended for use in installations and repairs where a reliable mechanical connection is needed without extensive rework of existing piping or fittings.

Advantages

This ARCO connector offers a compact design that simplifies transitions between 1/2" and 15 mm lines. Its mechanical construction provides a dependable joint suitable for both professional and DIY applications. The connector reduces the need for complex adaptors or custom machining and can save installation time by providing a ready-made coupling for mixed-dimension systems.

Suitable for

• Adapting 1/2" threaded or sized sections to 15 mm plumbing pipes
• Battery line assemblies requiring a 1/2" to 15 mm transition
• Repairing mixed-dimension domestic plumbing systems
• Professional HVAC, plumbing, and maintenance tasks needing a compact mechanical connector

Key specifications

• Connection sizes: 1/2" (imperial) to 15 mm (metric)
• Type: mechanical battery/plumbing connector
• Design: compact transition fitting for mixed-dimension connections
• Typical applications: pipe-to-pipe or pipe-to-line adaptation in plumbing and battery systems

How to use

Prepare both connection ends by cleaning and, if applicable, removing old sealant or corrosion to ensure a tight fit. Align the 1/2" side with the corresponding threaded or sized component and the 15 mm side with the mating pipe. Assemble according to common mechanical coupling practices for the materials involved, ensuring proper engagement and, where required, applying suitable sealing (thread tape or approved sealant) compatible with the system. Tighten to recommended torque for the specific pipe material and connection type to avoid leaks and mechanical stress.

Usage recommendations

Verify material compatibility (metal or alloy) with the fluids, pressure, and temperature of the system. For pressurized systems, follow applicable local codes and testing procedures after installation to confirm leak-free performance. If unsure about installation methods or sealing requirements, consult a qualified plumber or technician.
