Pipe Elbow 45° 16 mm PP‑R, Sony K4516 — pack of 50

Pipe Elbow 45° 16 mm PP‑R by Sony, model K4516, is a polypropylene‑random (PP‑R) fitting designed to connect 16 mm nominal diameter pipes at a 45° angle. Supplied as a pack of 50 pieces, this elbow is intended for use in PP‑R piping systems for cold and hot water installations where material compatibility is ensured. The fitting provides a compact directional change with steady internal flow characteristics and is suitable for residential and light commercial plumbing applications.

Advantages

The PP‑R construction offers chemical resistance and long service life under normal operating temperatures for plastic piping systems. The 45° angle reduces flow resistance compared with sharper bends, helping maintain hydraulic performance. The small 16 mm diameter makes the elbow suitable for compact installations and branched circuits. Supplied in a bulk pack of 50, the set supports multiple fittings for larger jobs or spare inventory.

Suitable for

• Residential potable water distribution using PP‑R pipes
• Hot and cold water lines where PP‑R is used and rated
• Directional changes in compact plumbing runs and manifolds
• Repair or replacement of existing PP‑R fittings

Key specifications

• Material: polypropylene‑random (PP‑R)
• Nominal diameter: 16 mm
• Angle: 45°
• Pack quantity: 50 pieces
• Typical application temperature range: compatible with standard PP‑R system temperatures for hot and cold water
• Connection type: socket for fusion joining with compatible PP‑R pipes

How to use

Prepare the PP‑R pipe ends by cutting square and removing burrs. Mark insertion depth and preheat the pipe and fitting sockets using a compatible PP‑R fusion heater to the temperature recommended by the heater manufacturer. Insert the pipe fully into the elbow socket, hold until the joint cools and solidifies, and avoid moving the joint during cooling. Ensure system pressure and temperature limits conform to the PP‑R piping specifications and perform pressure testing after installation in accordance with local codes and standards.

Usage recommendations

Use appropriate fusion welding equipment designed for PP‑R materials, follow manufacturer guidance for heating times and temperatures, and verify compatibility with the specific PP‑R pipe brand in the system. Store fittings in a dry, shaded area to avoid prolonged UV exposure prior to installation.
