Alkotest Kolano GZ with hanger 25 x 1/2 PP-R plumbing elbow

Alkotest Kolano GZ with hanger 25 x 1/2 PP-R plumbing elbow is a polypropylene-random (PP-R) transition fitting designed for connecting PP-R pipes to threaded components and securing runs to structures. One end provides a socket for 25 mm PP-R pipe, while the other end has a 1/2" male thread (GZ) for attaching valves, taps or other threaded fittings. The integrated hanger simplifies mounting and supports the piping to maintain alignment and reduce stress at the joint.

Advantages

The fitting combines a corrosion-resistant PP-R body with a threaded metal-compatible connection, offering chemical inertia, low thermal conductivity and long service life in potable water and heating systems. The built-in hanger provides immediate support during installation and helps prevent sagging without additional brackets. Its compact design enables space-efficient routing of pipework and straightforward transition between plastic piping and metal-threaded fixtures.

Suitable for

• Domestic and commercial potable water distribution
• Hot and cold water supply in heating systems
• Transitions from PP-R piping to threaded valves, taps or meters
• Applications requiring pipe support close to a fitting or at branch points

Key specifications

• Material: polypropylene random copolymer (PP-R)
• Pipe connection size: 25 mm socket
• Threaded connection: 1/2" male thread (GZ)
• Integrated hanger for structural attachment
• Suitable for potable water and heating installations

How to use

Prepare the PP-R pipe by cutting square and deburring the end, then clean mating surfaces to remove dirt and grease. Join the 25 mm PP-R pipe into the socket using the appropriate heat-fusion method for PP-R systems or follow manufacturer’s welding instructions to achieve a permanent, leak-free joint. Tighten the 1/2" male threaded connection to the mating component using appropriate sealant or tape on the thread as required by the system design. Secure the integrated hanger to the supporting structure using suitable fasteners, ensuring the fitting is aligned and the pipe run has correct slope and expansion allowances.

Usage recommendations

Confirm compatibility of thread type and sealing method with attached components before final assembly. Use recommended PP-R welding equipment and follow local plumbing codes for potable water and heating systems. Allow for thermal expansion and provide additional support intervals along long pipe runs.
