Coupling external repair D110, MAGNAPLAST — model 20180

MAGNAPLAST external repair coupling D110 (model 20180) is a mechanical pipe connector designed to reinstate or join pipes with a nominal diameter of 110 mm. Intended for external repair operations, this coupling creates a secure external sleeve around damaged or joined sections of plastic and other compatible pipes used in water, drainage and general utility systems. The design focuses on ease of installation and reliable sealing to support maintenance tasks as either a temporary or long-term solution.

Advantages

The coupling provides a robust external connection that reduces the need for extensive excavation or pipe replacement. Its construction allows for a tight mechanical grip and sealing around the pipe circumference, offering resistance to external mechanical stresses and typical pipeline pressures encountered in drainage and utility applications. The product is compatible with common pipeline materials and is suitable for both emergency repairs and planned maintenance works.

Suitable for

• Repairing external damage to 110 mm pipes in drainage systems
• Joining two lengths of 110 mm pipe during maintenance or installation
• Temporary or permanent external repairs on water and utility pipelines
• Situations where excavation or replacement is impractical

Key specifications

• Nominal pipe diameter: 110 mm
• Type: external repair coupling / mechanical sleeve
• Application: external pipe repairs and connections for water, drainage and utility systems
• Installation: external mounting around existing pipe circumference
• Performance: designed for mechanical sealing and resistance to pipeline pressures typical for drainage and utility use

How to use

Prepare the pipe by cleaning the area around the damage or joint to remove dirt, debris and loose material. Position the coupling around the pipe so the damaged section or joint is centered under the sleeve. Tighten the coupling according to manufacturer guidance to achieve uniform compression and seal against the pipe surface; ensure bolts or fasteners are torqued evenly to avoid gaps. After installation, inspect the sealed area for leaks and retighten fasteners if necessary following a short pressure test or operational check.

Usage recommendations

Confirm material compatibility before installation and follow local regulations for pressure testing and repair procedures. Use appropriate tools for even tightening and, when used in pressurized systems, perform a controlled pressure test after installation. For long-term or high-pressure applications consult a qualified technician to verify suitability and installation method.
