Compression Reducing Coupling Comap 32x3 → 26x3 for Plumbing Connections

Compression reducing coupling Comap 32x3 → 26x3 is a metal plumbing fitting designed to join two pipes of different outer diameters using compression ends. The coupling provides a compact mechanical transition between a 32x3 pipe and a 26x3 pipe, creating a stable sealed joint suitable for potable water distribution and heating circuits when installed on compatible metal or multilayer pipes.

Advantages

The coupling delivers a secure, permanent mechanical connection without the need for soldering or complex joining tools. Its compression ends allow for reliable sealing under normal operating pressures in domestic and light-commercial plumbing systems. The compact design saves installation space and simplifies transitions between different pipe sizes while maintaining flow continuity and reducing potential leak points.

Suitable for (tasks / use cases)

• Connecting a 32x3 metal or multilayer pipe to a 26x3 metal or multilayer pipe
• Transitions in potable water distribution systems
• Connections in residential or small commercial heating circuits
• Repair or alteration where downsizing of pipe diameter is required

Key specifications

• Type: Compression reducing coupling
• Input pipe diameter: 32 mm (wall thickness 3 mm)
• Output pipe diameter: 26 mm (wall thickness 3 mm)
• Material: metal construction suitable for mechanical compression joining
• Connection method: compression ends for press-fit style installation
• Application: potable water and heating distribution
• Installation orientation: inline straight coupling

How to use

Prepare both pipe ends by cutting squarely and deburring the inner and outer edges. Slide the compression components onto each pipe end as specified by the coupling manufacturer, then push the pipes fully into the coupling until they reach the internal stops. Tighten the compression nuts or apply the required press action according to the installer instructions for compression fittings to achieve a secure mechanical seal. After installation, inspect the joint and perform a pressure test following system and local regulations to confirm leak-free performance.

Usage recommendations

Use this coupling with pipes of compatible materials and the specified wall thicknesses to ensure proper sealing. Do not overtighten compression nuts; follow the torque or press force guidance provided by the fitting manufacturer. Verify that the coupling is suitable for the intended working pressure and fluid type before installation.
