Adaptor Coupling 121-137mm / 108-122mm MAC4000


The MAC4000 Adaptor Coupling is a premium-quality flexible coupling designed for secure and reliable connections between pipes of differing sizes. Manufactured from durable EPDM rubber with stainless steel banding, this coupling provides a watertight seal ideal for civil engineering, drainage, and plumbing applications.

Product Features/Specifications:

This black rubber coupling features dual stainless steel clamping bands, enabling a tight and durable seal between pipes ranging from 121–137mm and 108–122mm in diameter. Resistant to corrosion and chemical degradation, it is ideal for both above and below-ground installations.

Detailed Product Benefits:

The MAC4000 Adaptor Coupling excels in challenging environments due to its high-performance materials. The EPDM rubber body offers exceptional flexibility and weather resistance, making it suitable for a wide range of pipe materials such as clay, cast iron, PVC, and concrete. The stainless steel bands provide a strong, non-corrosive clamping force that ensures long-term stability under pressure and movement—perfect for renovation or repair work where pipe misalignment is common.

Applications and Versatility:

Ideal for use in drainage systems, sewer connections, stormwater infrastructure, and general underground pipe installations, this adaptor coupling is especially suited for retrofits and repairs where pipe sizes differ slightly. Whether you're working in residential, commercial, or municipal projects, the MAC4000 offers a hassle-free solution with a professional-grade finish. Its versatility also makes it suitable for temporary fixes or long-term installations.
