## Summary description

WAVIN compression coupling for 20 mm polypropylene pipes, model 3248042501, rated PN20/20C. Designed to connect and seal straight pipe joints in plastic piping systems. Provides a durable mechanical connection without welding; suitable for potable water, heating and general plumbing applications where a PN20 pressure rating is required. Easy to install and maintain.

## Long description

WAVIN compression coupling 20 mm PN20/20C is a mechanical joining fitting designed for straight connections of 20 mm polypropylene pipes. The coupling provides a reliable sealed joint without the need for welding or solvent cement, enabling quick assembly and straightforward maintenance in pressurized plastic piping systems. It is intended for applications requiring a PN20 pressure rating and is compatible with standard 20 mm polypropylene piping used in potable water, heating circuits and general plumbing installations.
Advantages
The coupling offers a compact design that maintains flow continuity and minimizes pressure drop. Its compression sealing system creates a secure, leak-resistant joint while allowing disassembly if system modifications are needed. Materials and construction are selected to withstand PN20 operating pressures and typical temperatures encountered in domestic and light commercial water and heating systems. Installation requires only basic tools and reduces downtime compared with welded or glued connections.
Suitable for
 Connecting straight runs of 20 mm polypropylene pipes
 Potable water distribution systems
 Domestic and small commercial heating circuits
 Plumbing repairs and retrofit projects
 Temporary or modular piping installations
Key specifications
 Pipe diameter compatibility: 20 mm polypropylene pipes
 Rated pressure class: PN20
 Connection type: compression coupling for straight pipe joint
 Suitable media: potable water, heating fluids and general plumbing media
 Service temperature: suitable for typical domestic heating and hot/cold water ranges (consult system requirements)
 Maintenance: removable and reusable design for inspection and replacement
How to use
Prepare pipe ends by cutting square and ensuring they are clean and free from burrs or deformation. Slide the coupling components onto each pipe end according to the manufacturer’s assembly sequence, then insert the pipe fully into the fitting until it reaches the internal stop. Tighten the compression nut(s) evenly using appropriate hand or standard tools until a secure seal is achieved; avoid over-tightening. Verify alignment and perform a pressure test at the system’s working pressure to confirm leak-free performance before putting the circuit into regular operation.
Usage recommendations
Use the coupling only with compatible 20 mm polypropylene pipes and within the specified PN20 pressure and temperature limits. For potable water and heating applications, follow local regulations and installation codes. If in doubt about system compatibility or for high-temperature/high-pressure duty beyond typical domestic ranges, consult technical documentation or a qualified installer.
