Pipe Coupling MAGNAPLAST HTUG for Cast Iron Pipes 75 mm (model 12620)

MAGNAPLAST HTUG pipe coupling for cast iron pipes, 75 mm nominal diameter (model 12620) is a mechanical connector designed to join and seal sections of cast iron drainage and sewer piping. The coupling provides a watertight connection between compatible cast iron pipe ends and is intended for gravity drainage systems, repair works and new installations where a durable, pressure-resistant joint is required. Constructed for ease of installation, it ensures alignment and reliable sealing without the need for complex tools.

Advantages

The coupling offers a compact solution that simplifies the replacement or extension of cast iron pipe runs. Its design delivers consistent compression and sealing performance to prevent leaks and infiltration. The product is suitable for use in visible and underground applications where a robust mechanical joint is necessary. It reduces installation time compared with traditional flange or soldered connections and enables straightforward maintenance access.

Suitable for

• Repairing damaged sections of cast iron drainage or sewer pipes
• Connecting new cast iron pipe segments in gravity drainage systems
• Temporary or permanent mechanical joints in building drainage
• Retrofitting or extending existing cast iron pipeline layouts

Key specifications

• Nominal diameter: 75 mm (for compatible cast iron pipe ends)
• Type: mechanical pipe coupling for drainage and sewer applications
• Sealing: elastomeric sealing element for watertight connection
• Material characteristics: corrosion-resistant components suitable for buried and above-ground use
• Application environment: designed for gravity drainage systems in buildings and civil installations

How to use

Prepare pipe ends by cleaning and ensuring mating faces are free of debris, rust flakes and excessive irregularities. Slide the coupling components onto pipe ends, align the pipes to achieve correct axial positioning and engage the coupling so the elastomeric seal seats uniformly over the pipe circumference. Tighten any external fasteners according to manufacturer torque recommendations until a continuous compression seal is formed. After installation, inspect the joint for even compression and perform a leak test where accessible and required by local standards.

Usage recommendations

Use the coupling only on compatible cast iron pipes with matching outside diameter and spigot/socket style. Do not use on pressurized water mains unless product specifications explicitly permit pressure service. For underground installations, ensure appropriate bedding and backfill to avoid point loads on the joint. Follow local building codes and standards for drainage system assembly and testing.
