Plumbing elbow Alkotest Kolano GW 25 x 1/2 PP-R for pipe connection

Alkotest Kolano GW 25 x 1/2 PP-R is a polypropylene-random (PP-R) plumbing elbow designed to connect a 25 mm pipe to a fitting with a 1/2-inch threaded connection. The compact elbow provides a secure angle joint for hot and cold water distribution systems in residential and light commercial installations. Made from corrosion-resistant PP-R material, it resists chemical degradation and scale buildup typical in water systems and maintains dimensional stability at normal operating temperatures.

Advantages

The PP-R construction offers long-term resistance to corrosion and minimizes interaction with potable water chemistry. Its molded design ensures leak-resistant joints when installed with compatible pipe and fittings, while the combination of a 25 mm socket and 1/2-inch threaded outlet enables easy adaptation between metric piping and common threaded fittings. The lightweight plastic reduces handling effort and avoids galvanic corrosion issues present with metallic fittings.

Suitable for

• Hot and cold potable water distribution in homes and apartments
• Plumbing connections where a 25 mm PP-R pipe must interface with a 1/2-inch threaded fixture
• Light commercial plumbing installations requiring corrosion-resistant fittings
• Repair or replacement of elbow joints in existing PP-R piping systems

Key specifications

• Material: Polypropylene-random (PP-R)
• Pipe connection diameter: 25 mm (socket)
• Threaded outlet size: 1/2 inch (female/male as per product designation)
• Intended media: Hot and cold potable water
• Typical application: Angle elbow for pipe-to-thread connections
• Resistance: Corrosion and chemical resistance typical of PP-R

How to use

Prepare the 25 mm PP-R pipe by cutting squarely and deburring the end. Join the pipe into the 25 mm socket using the appropriate PP-R welding or fusion method recommended for the piping system to achieve a secure, permanent joint. Attach the 1/2-inch threaded connection to the mating threaded fitting using suitable sealing tape or joint compound for plumbing threads, ensuring correct thread engagement and leak-tightness. Follow standard plumbing practices for system testing and flushing after installation.

Usage recommendations

Use compatible PP-R fusion tools and follow manufacturer guidelines for welding temperatures and cooling times. Verify the direction and type (male or female) of the 1/2-inch thread before installation and apply appropriate thread sealant. Do not expose the fitting to open flame or solvents; avoid mechanical stresses beyond normal pipe movement and support the piping to prevent excessive load on the elbow joint.
