Compression coupling ALFA RK Mufa PE 100 DN 90 SDR 11 PN 16 art. 3001 (DWZ)

Compression coupling ALFA RK Mufa PE 100 DN 90 SDR 11 PN 16 art. 3001 (DWZ) is a mechanical connector designed for joining or repairing polyethylene (PE 100) pipes. It is sized for nominal diameter DN 90 with SDR 11 wall thickness and rated for operating pressures up to PN 16. The coupling provides a pressure-resistant, watertight joint that matches standard PE 100 pipe dimensions and is intended for use in water distribution, sewage and irrigation systems.

Advantages

The coupling offers a simple, tool-assisted assembly that does not require heat fusion, allowing fast installation and reduced downtime. Its compression design ensures a consistent sealing force around the pipe circumference, minimizing leak risk under rated pressure. Constructed to fit SDR 11 PE 100 pipes, the component maintains structural compatibility with common polyethylene pipe systems and supports reliable mechanical performance in buried and above-ground applications.

Suitable for

• Joining DN 90 PE 100 pipes with SDR 11 wall thickness
• Repairing damaged sections of water supply pipelines
• Connecting segments in irrigation and agricultural distribution networks
• Non-permanent or serviceable connections in sewage and drainage systems

Key specifications

• Material compatibility: Polyethylene PE 100
• Nominal diameter: DN 90
• Standard dimension ratio: SDR 11
• Pressure rating: PN 16
• Connection type: Compression coupling (mechanical, gasketed)
• Suitable installation environment: buried or exposed piping systems for water, sewage, and irrigation

How to use

Prepare pipe ends by cutting square and removing burrs or debris to ensure full contact with the sealing elements. Slide the coupling components onto pipe ends according to the manufacturer's orientation, insert pipe ends to the required insertion depth, and tighten the compression elements evenly until the specified torque or compression indication is achieved. Verify alignment and inspect the joint visually for even compression of the gasket. Perform a pressure test in accordance with system requirements to confirm a leak-free connection before returning the pipeline to service.

Usage recommendations

Use the coupling only with PE 100 pipes of matching DN 90 and SDR 11 dimensions. Follow recommended tightening torques and installation sequence provided by the manufacturer. For buried installations, ensure proper bedding and backfill to avoid point loads on the joint. If the application involves aggressive chemicals, extreme temperatures, or pressures above PN 16, consult technical documentation or choose a product rated for those conditions.
