The MDC115 Mission Coupling is a premium flexible connector designed to securely join 100mm PVC pipework to 100mm cast iron pipes. Manufactured using high-grade elastomeric rubber and reinforced stainless steel bands, this coupling ensures a strong, watertight, and reliable seal suitable for both new and existing drainage systems.
Product Features/Specifications:
This coupling features a durable EPDM rubber body supported by stainless steel clamping bands engineered to deliver consistent pressure around both pipe types. Its flexible design accommodates the size and surface variations commonly found between PVC and cast iron materials, providing a smooth and secure transition.
Detailed Product Benefits:
Designed for long-term underground performance, the MDC115 coupling offers superior resistance to chemical exposure, moisture, temperature changes, and soil movement. The EPDM rubber sleeve absorbs vibration and minor misalignment, while the stainless steel bands provide a stable, leak-proof seal.
This coupling is ideal for adapting older cast iron systems to modern PVC pipework without the need for specialist adaptors or extensive modifications. The flexible construction compensates for uneven pipe edges, corrosion wear on cast iron, and slight dimensional differences, enhancing the reliability and durability of the entire drainage installation.
Applications and Versatility:
The MDC115 is suitable for underground drainage, soil stack repairs, sewer line upgrades, and mixed-material transitions where 100mm PVC pipes must be connected to 100mm cast iron. It is widely used in property refurbishments, system upgrades, maintenance jobs, and renovations where traditional materials interface with contemporary pipework.
