MAG1200 Magnum Coupling 1200mm to 1299mm Pipe Diameter

Fernco MAG1200 drain coupling with a shear banded seal, suitable for pipe with an outside diameter of 1200mm to 1299mm. Manufactured from EPDM rubber, incorporating a Grade 1 304 stainless steel shear band. Fernco magnum couplings are manufactured with a width of 370mm, specifically created to join and repair large diameter pipes used in sewer, drain and other civil and below ground applications. The larger width enables a higher tolerance when cutting through pipework, and a greater tolerance for movement during any ground settling.

The Fernco MAG1200 Magnum Coupling is an ultra-heavy-duty flexible connector designed for very large drainage pipe connections where maximum clamp strength, sealing reliability and long-term durability are essential. Built for extreme conditions, this coupling is ideal for major industrial, commercial and infrastructure drainage systems.

Manufactured from a thick, high-performance EPDM rubber sleeve and reinforced with multiple ultra-heavy-duty stainless steel clamp bands, the MAG1200 delivers exceptional torque retention and resistance to loosening. This ensures a secure airtight and watertight seal even when exposed to vibration, ground movement and temperature variation. The flexible rubber body compensates for minor pipe misalignment and supports smooth transitions between PVC, clay, concrete and cast iron pipework.

Installation is straightforward using standard hand tools, helping reduce labour time on large-scale projects while maintaining professional-grade results. Designed to withstand harsh site conditions and heavy mechanical load, the MAG1200 offers dependable long-term performance where standard and shear-banded couplings are not sufficient.
