PP-R 45° Elbow 63 mm pipe fitting, KAN-therm K4563 (pack of 5)

PP-R 45° Elbow 63 mm pipe fitting from KAN-therm, model K4563, is a polypropylene-random (PP‑R) fusion fitting designed for hot and cold water systems. Supplied as a pack of five, the elbow provides a 45-degree change of direction while preserving the integrity of fusion joints typical for PP‑R piping. The fitting is intended for use with 63 mm diameter PP‑R pipes in plumbing, heating circuits and potable water installations where a durable, chemically stable connection is required.

Advantages

The PP‑R material offers resistance to corrosion, scale and many common chemicals used in domestic and commercial systems, ensuring long-term dimensional stability. Fusion joints formed with compatible PP‑R pipes create leak-tight, homogeneous connections that reduce the risk of joint failure compared with mechanical fittings. The 45° geometry enables smoother flow transitions and easier alignment in piping runs, which can minimize pressure losses and simplify installation in confined spaces.

Suitable for

• Domestic and commercial plumbing systems using PP‑R pipework
• Central heating circuits and underfloor heating manifolds
• Potable water installations where approved PP‑R materials are specified
• Sections of piping requiring directional changes with reduced flow disturbance

Key specifications

• Material: polypropylene-random (PP‑R)
• Angle: 45 degrees
• Nominal pipe size compatibility: 63 mm outer diameter
• Pack quantity: 5 fittings
• Intended use: hot and cold water systems, potable water, heating circuits

How to use

Prepare matching 63 mm PP‑R pipe ends by cutting square and deburring the inner and outer edges. Use the appropriate PP‑R fusion welding tool or socket fusion heater set to the manufacturer’s recommended temperature for the material. Insert the pipe and fitting onto the heating elements for the specified heating time, then remove and immediately join, ensuring correct axial alignment and maintaining pressure until the joint cools. Allow sufficient cooling time before pressurizing the system and follow standard installation practices for PP‑R systems, including support spacing and thermal expansion allowances.

Usage recommendations

Verify compatibility of the fitting with the specific PP‑R pipe brand and adhere to relevant local plumbing codes. Use certified fusion equipment, follow the supplier’s fusion parameters, and test the completed system for leaks and pressure before commissioning.
