## Summary description

Alkotest PP-R pipe coupling with half-nut, size 20 x 3/4. Designed for joining polypropylene-random (PP-R) piping to threaded 3/4" fittings, the coupling features a 20 mm socket and a 3/4" male/female threaded connection. Suitable for plumbing systems, heating circuits and potable water installations where a transition between welded PP-R pipe and threaded components is required.

## Long description

Alkotest PP-R pipe coupling with half-nut 20 x 3/4 is a transition fitting designed to connect 20 mm polypropylene-random (PP-R) pipe to a 3/4" threaded fitting. The coupling combines a socket for heat-fused PP-R pipe and a threaded half-nut section to secure a standard 3/4" male or female thread, allowing a reliable connection between plastic piping and threaded metal or plastic components in plumbing and heating systems.
Advantages
The coupling provides a secure mechanical and pressure-resistant joint where welded PP-R piping must interface with threaded fittings. Its design reduces the need for additional adapters and minimizes potential leak points by integrating the socket and threaded section in a single unit. Compatibility with standard 3/4" threads and a 20 mm PP-R socket makes installation straightforward in mixed-material systems, and the PP-R material ensures corrosion resistance and suitability for potable water and heating applications.
Suitable for
 Joining 20 mm PP-R pipe to 3/4" threaded valves, taps or fittings
 Domestic and commercial plumbing systems
 Heating circuits where a transition to threaded components is required
 Potable water installations and risers
Key specifications
 Pipe socket diameter: 20 mm for PP-R pipe
 Thread size: 3/4" (compatible with standard 3/4" male/female threads)
 Material: polypropylene-random (PP-R) body with threaded half-nut section
 Connection types: heat-fusion socket for PP-R and threaded mechanical connection
 Typical applications: potable water, heating circuits, plumbing transitions
How to use
Prepare the PP-R pipe by cutting a clean, square end and ensuring the outside diameter matches the 20 mm socket. Use an appropriate PP-R welding tool to fuse the pipe into the coupling socket following the welding tool manufacturer's temperature and time settings. Threaded components should be wrapped with appropriate sealing tape or joint compound compatible with potable water systems before tightening the 3/4" connection into the half-nut. After assembly, verify the joint visually and perform a pressure test in accordance with local plumbing standards.
Usage recommendations
Install in accordance with applicable plumbing and heating regulations. Use approved PP-R welding equipment and follow manufacturer guidelines for temperature, insertion depth and cooling time. For potable water systems, use sealing materials certified for drinking water. Avoid overtightening threaded connections to prevent damage to plastic components.
