Reducer coupling Unidelta PE 40 x 32 mm (model 601140) for polyethylene pipes

Unidelta reducer coupling PE 40 x 32 mm is a polyethylene pipe fitting designed to connect and reduce between 40 mm and 32 mm PE pipes. This mechanical coupling creates a secure joint suitable for water supply and irrigation systems where a change of pipe diameter is required. Constructed from compatible PE material, the fitting is intended for use with polyethylene piping in potable water, garden irrigation and buried installations.

Advantages

The coupling offers a straightforward mechanical connection without the need for specialized equipment. Its polyethylene construction ensures chemical compatibility and corrosion resistance typical of PE piping systems. The design allows for reliable diameter transitions while maintaining flow continuity and mechanical stability under normal operating conditions.

Suitable for

• Joining 40 mm to 32 mm polyethylene (PE) pipes
• Domestic and commercial potable water distribution
• Garden and agricultural irrigation lines
• Underground buried PE pipe installations

Key specifications

• Material: polyethylene (PE)
• Connection type: reducer coupling for mechanical joint between two pipe diameters
• Compatible diameters: 40 mm and 32 mm
• Application: water supply, irrigation, buried piping

How to use

Ensure both pipe ends are clean, cut squarely and free of burrs before installation. Slide the coupling onto the larger or smaller pipe end as applicable and align the pipes to achieve full insertion. Follow standard assembly procedures for PE mechanical couplings, ensuring seals and compression elements (if present) are positioned correctly and tightened according to manufacturer guidance. After assembly, inspect the joint and perform a pressure test in accordance with system requirements to verify leak-free performance.

Usage recommendations

Use the reducer coupling only with compatible PE pipes of the specified diameters. Store fittings protected from prolonged UV exposure and install in accordance with local plumbing codes and best practices. For potable water applications, verify that the complete system materials comply with local drinking water regulations.
