## Summary description

Compression reducing coupling Comap PWE 63x4.5–40x3.5 is a press-fit pipe connector designed to join pipes of different diameters. Constructed for reliable hydraulic sealing, it fits a 63 mm pipe with 4.5 mm wall to a 40 mm pipe with 3.5 mm wall. Suitable for plumbing, heating and potable water systems where a permanent, press-pressed transition is required.

## Long description

Compression reducing coupling Comap 63x4.5 to 40x3.5 (PWE) is a press-fit pipe connector engineered to join a 63 mm pipe with 4.5 mm wall thickness to a 40 mm pipe with 3.5 mm wall thickness. Manufactured by Comap for permanent press-pressed transitions, this coupling provides a compact solution for hydraulic systems where a change of diameter is required while maintaining a sealed metal-to-metal connection suitable for potable water, heating and plumbing installations.
Advantages
The Comap reducing coupling offers a secure, leak-resistant press connection that minimizes assembly time compared with soldering or threaded joints. Its construction is optimized for hydraulic sealing and dimensional stability under typical domestic and commercial water pressures. The product is designed for permanent installation and compatibility with press-fitting tools and procedures commonly used in plumbing and heating systems.
Suitable for
 Transitioning between 63 mm (4.5 mm wall) and 40 mm (3.5 mm wall) copper or compatible press-fit pipes
 Domestic and commercial heating circuits
 Potable water distribution where a permanent press connection is required
 Plumbing systems requiring a compact, low-profile diameter reduction
Key specifications
 Type: Compression reducing coupling, press-fit (PWE)
 Large end outer diameter: 63 mm
 Large end wall thickness: 4.5 mm
 Small end outer diameter: 40 mm
 Small end wall thickness: 3.5 mm
 Application: potable water, heating and plumbing systems
 Connection method: press-pressed permanent joint
How to use
Prepare both pipe ends by cutting square and deburring inner and outer edges. Verify pipe outer diameters and wall thicknesses match 63x4.5 and 40x3.5 before assembly. Insert pipes fully into the respective ends of the coupling, ensuring correct seating depth. Use the appropriate press-fitting tool and jaw size for the coupling material and diameters, and perform the pressing operation following the tool manufacturer's instructions to create a permanent hydraulic seal. After pressing, inspect the joint visually and, if required by local practice, perform a pressure test to verify integrity.
Usage recommendations
Use only with compatible press-fit pipes and approved pressing jaws for the specified diameters. Ensure pipes are free of contamination and correctly prepared before pressing. For installations carrying potable water or operating under higher temperatures and pressures, follow applicable standards and local regulations and, when in doubt, consult a qualified installer.
