Compression sleeve fitting Comap Mufa zaprasowywana 40x3,5 for copper/aluminum pipes

Comap Mufa zaprasowywana 40x3,5 is a compression sleeve fitting designed for creating a permanent mechanical joint on pipes with an outer diameter of 40 mm and a wall thickness of 3.5 mm. Manufactured by Comap, this fitting provides a solid, leak-resistant connection for plumbing and heating systems when used on copper and compatible metallic pipes. The product is intended for professional and DIY applications that require reliable pipe joining without soldering.

Advantages

The compression sleeve delivers a secure, durable connection that resists axial pull and typical system pressures found in domestic and light commercial plumbing. Installation does not require heat or soldering, reducing fire risk and enabling installation in confined spaces. The fitting’s design ensures consistent compression over the specified pipe dimensions, resulting in a watertight seal when installed according to manufacturer guidance.

Suitable for

• Joining copper pipes with outer diameter 40 mm and wall thickness 3.5 mm
• Connecting compatible metallic pipes of similar dimensions
• Plumbing repairs and patching existing lines
• Extending heating and hot-water distribution circuits
• Situations where solder-free mechanical joints are preferred

Key specifications

• Pipe outer diameter: 40 mm
• Pipe wall thickness compatibility: 3.5 mm
• Material compatibility: copper and compatible metals
• Connection type: compression (press) sleeve fitting
• Intended application: plumbing and heating systems

How to use

Ensure the pipe ends are cut square, deburred and clean before installation. Slide the compression sleeve over the pipe and position the sleeve centered on the joint between the two pipe ends. Use the appropriate pressing tool or crimping equipment specified for compression fittings of this type to apply the required compression evenly until the joint is completed. After pressing, inspect the joint visually and perform a pressure test in accordance with system standards to verify leak tightness.

Usage recommendations

Use this compression sleeve only on pipes that match the specified outer diameter and wall thickness. Follow the pressing tool manufacturer’s instructions and local plumbing codes. For repairs on existing systems, depressurize and drain the line before beginning work. Periodic inspection after installation is recommended to confirm long-term integrity.
