Angle adapter/coupling Detal-met Kolano PP 25 mm with 1/2" female thread

Detal-met Kolano PP is a polypropylene 90° angle adapter designed to connect 25 mm plastic piping to a 1/2" female threaded fitting. The coupling provides a reliable right-angle transition between PP piping systems and threaded components such as valves, faucets or other fittings. Intended for use in water supply and heating installations, the adapter ensures a secure mechanical and threaded connection where a PP-to-thread interface is required.

Advantages

The polypropylene construction offers chemical resistance and low weight while maintaining dimensional stability for plumbing applications. The integrated 1/2" female thread allows direct attachment of standard threaded metal or plastic fittings without additional adapters. The 90° geometry simplifies routing in tight spaces and reduces the need for multiple fittings. The component is compatible with common plastic piping joining methods for easy installation in domestic and light-commercial systems.

Suitable for

• Connecting 25 mm polypropylene pipes to 1/2" threaded valves or taps
• Water supply lines in residential and commercial buildings
• Heating circuits where a PP-to-thread transition is required
• Retrofit and repair work requiring a right-angle threaded connection

Key specifications

• Material: polypropylene (PP)
• Pipe connection size: 25 mm
• Thread type: female 1/2" (standard pipe thread)
• Angle: 90 degrees
• Application: water supply and heating systems

How to use

Prepare the 25 mm pipe end according to the chosen joining method (cut square, deburr and clean). Join the pipe to the adapter using an appropriate technique for PP piping (e.g., solvent welding, mechanical compression or fusion method compatible with the adapter design). Ensure the threaded 1/2" connection is sealed with suitable thread sealant or tape before tightening the mating fitting by hand and then with a wrench to the required torque. Verify alignment and check for leaks after pressurising the system.

Usage recommendations

Use compatible joining methods and sealants rated for potable water and heating systems. Avoid excessive torque on the 1/2" female thread to prevent damage to the polypropylene housing. Inspect connections periodically after installation and follow local plumbing codes for installation and testing.
