MAG900 Magnum Coupling 900mm to 999mm Pipe Diameter

Fernco MAG900 drain coupling with a shear banded seal, suitable for pipe with an outside diameter of 900mm to 999mm. 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 MAG900 Magnum Coupling is an extreme-duty flexible connector designed for very large diameter drainage pipe connections where maximum strength, sealing security and long-term durability are essential. Part of Ferncos Magnum (MAG) range, this coupling is engineered for major commercial, industrial and infrastructure drainage systems operating under demanding conditions.

Manufactured from a thick, high-performance EPDM rubber sleeve and reinforced with multiple ultra-heavy-duty stainless steel clamp bands, the MAG900 delivers exceptional clamp force and superior torque retention. This ensures a secure airtight and watertight seal even when exposed to vibration, structural movement and temperature variation. The flexible 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 MAG900 offers dependable long-term performance where standard and shear-banded couplings are not sufficient.
