Reduction coupling Unidelta PE 32 x 25 mm, model 601132

Unidelta reduction coupling PE 32 x 25 mm is a polyethylene pipe fitting designed to join pipes with 32 mm and 25 mm outer diameters. The reducer creates a secure transition between two sizes of PE pipe for potable water distribution, irrigation systems and low-pressure fluid lines. It is intended for mechanical joining in plumbing and outdoor installations where a change of pipe diameter is required.

Advantages

The coupling is made from durable polyethylene, providing resistance to corrosion, chemical exposure and environmental stress. Its simple mechanical design allows for straightforward installation without fusion welding, reducing on-site work time. The compact reducer offers a stable connection between different pipe sizes while maintaining flow continuity and minimizing turbulence at the diameter change.

Suitable for

• Garden and agricultural irrigation lines
• Low-pressure water distribution systems
• Outdoor plumbing and drainage runs
• Temporary or permanent pipe repairs involving a size transition

Key specifications

• Material: polyethylene (PE)
• Connection type: mechanical coupling for outer diameters
• Compatible pipe outer diameters: 32 mm and 25 mm
• Intended operating pressure: suitable for typical low-pressure applications (irrigation and distribution)
• Application environment: indoor and outdoor use, including buried and exposed installations

How to use

Prepare pipe ends by cutting square and removing burrs, ensuring clean, dry surfaces. Slide the coupling onto one pipe end, align the second pipe of the other diameter, and push firmly until the pipes seat fully into the reducer. Check alignment and ensure the mechanical connection is engaged according to standard practice for PE fittings. If required by the installation method, secure with appropriate clamps or fittings compatible with polyethylene couplings.

Usage recommendations

Verify pipe outer diameters before installation and use appropriate tools to achieve square cuts. Avoid exposing the fitting to solvents or extreme mechanical stress. For buried installations, follow local guidelines for bedding and backfill to prevent point loads on the coupling. For pressurized applications, confirm that system pressure remains within the recommended range for PE mechanical fittings.
