Coupling sleeve (mufa) Detal-met M40 40 mm polypropylene pipe connector

Detal-met M40 coupling sleeve is a polypropylene pipe connector designed to join two sections of 40 mm plastic pipe in a straight line. The simple sleeve-style design provides a leak-resistant joint when used with compatible 40 mm PP pipes and appropriate installation technique. Intended for drainage, wastewater, and general plumbing lines, this coupling supports repair, extension, or new installations in residential and light commercial systems.

Advantages

The coupling sleeve is made of durable polypropylene that resists corrosion, chemical exposure, and typical household wastewater conditions. Its plain-ended sleeve form allows quick insertion of pipe ends and straightforward alignment for a continuous flow path. Lightweight construction simplifies handling during installation and replacement, while the smooth internal bore helps minimise flow resistance and sediment accumulation.

Suitable for

• Connecting two lengths of 40 mm polypropylene drainage or sewage pipe
• Repairing a damaged section of plastic waste or drainage line
• Extending existing 40 mm PP pipe runs in kitchens, bathrooms, and utility areas
• Temporary or permanent joints in light commercial plumbing systems

Key specifications

• Material: polypropylene (PP)
• Nominal pipe diameter compatibility: 40 mm
• Connector type: straight sleeve coupling
• Connection end style: plain, push-in or solvent/sealant compatible depending on installation method
• Typical applications: drainage, wastewater, sewage, general plumbing

How to use

Ensure the 40 mm polypropylene pipe ends are clean, squarely cut and free of burrs before installation. Dry-fit the pipes into the sleeve to check alignment and insertion depth. Depending on the chosen assembly method, apply the recommended sealing technique: use an appropriate rubber gasket or elastic seal for push-fit joints, or follow adhesive/solvent manufacturer instructions for bonded joints compatible with PP. Insert pipe ends fully into the sleeve, verify straight alignment, and allow any adhesive or sealant to cure as specified prior to pressurising or exposing the joint to flow.

Usage recommendations

Use this coupling with pipes of matching 40 mm nominal diameter and compatible material. Confirm whether a gasket, solvent or additional clamps are required for a secure joint in your specific system. For installations exposed to mechanical stress or external loads, consider additional support, proper bedding, or using reinforced connectors. Follow local plumbing codes and adhesive manufacturers’ instructions where applicable.
