## Summary description

Compression adapter (złączka) ALFA RK model 601520 for use with 20 mm PE (polyethylene) piping and 1/2" male threaded fittings. Designed to join PE pipe to standard 1/2" threaded valves or fixtures. Useful in plumbing and heating installations for secure, leak-resistant connections between plastic pipe and metal-threaded components.

## Long description

Compression adapter ALFA RK 20 mm to 1/2" male (model 601520) is a coupling component designed to connect 20 mm polyethylene (PE) pipe to standard 1/2" male threaded fittings. The adapter provides a compression-style joint on the PE side and a male threaded connection on the other, enabling secure transitions between plastic distribution lines and metal-threaded valves, taps, or fixtures in plumbing and heating systems.
Advantages
The adapter offers a compact design that simplifies the transition from PE pipework to 1/2" threaded components without the need for additional fittings or complex tools. Its compression mechanism ensures a tight, leak-resistant connection when installed according to instructions. The combination of plastic-compatible compression and standard metal threading makes the fitting versatile for a range of installations where a reliable interface between plastic tubing and threaded fixtures is required.
Suitable for
Connecting 20 mm PE supply lines to 1/2" threaded valves and taps
Domestic plumbing repairs and extensions
Heating circuits where PE pipe meets metal-threaded components
Utility and service connections for water distribution
Key specifications
Pipe connection type: compression fitting for 20 mm polyethylene (PE) pipe
Thread type: external 1/2" male thread compatible with standard 1/2" female fittings
Material compatibility: designed for use with PE piping and metal-threaded fixtures
Application area: plumbing and heating installations for water distribution
Connection method: compression seal on pipe side, threaded seal on fittings side
How to use
Prepare the 20 mm PE pipe by cutting the end square and removing any burrs. Slide the compression nut and compression ring (if separate) onto the pipe, insert the pipe fully into the adapter body until it seats, then tighten the compression nut by hand and finish with a suitable spanner to secure the joint without over-tightening. Apply appropriate thread sealant or tape to the 1/2" male thread before connecting to the female threaded valve or fixture, then tighten to achieve a leak-free connection. Follow standard installation practices for PE pipework and ensure the assembled joint is accessible for inspection.
Usage recommendations
Use the adapter within the intended temperature and pressure ranges of the connected piping system. Avoid excessive torque on the compression nut to prevent deformation of the PE pipe; if a persistent leak occurs after correct installation, inspect the pipe end for damage and replace the compression ring if applicable. When joining to metal fittings, ensure compatible materials and appropriate thread sealing methods are used to maintain long-term leak resistance.
