MAG1700 Magnum Coupling 1700mm to 1799mm Pipe Diameter

Fernco MAG1700 drain coupling with a shear banded seal, suitable for pipe with an outside diameter of 1700mm to 1799mm. 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 MAG1700 Magnum Coupling is engineered for extra-large drainage pipe connections where maximum clamp force and long-term sealing confidence are critical. Designed for high-load drainage environments, this coupling delivers a robust, flexible and durable joint for major infrastructure and industrial drainage systems.

Constructed from premium EPDM rubber and reinforced with multiple high-strength stainless steel clamp bands, the MAG1700 provides exceptional torque retention and resistance to movement under load. Its flexible body accommodates slight pipe misalignment while ensuring a consistent airtight and watertight seal across mixed pipe materials.

Installation is efficient using standard tools, helping minimise downtime on major projects. With excellent resistance to corrosion, vibration and environmental stress, the MAG1700 is built for long service life in extreme drainage conditions.
