AC3209 EPDM Adaptor Coupling 265-290mm to 295-320mm

The Fernco AC3209 EPDM Adaptor Coupling gives you a secure, flexible transition between unequal large-diameter drainage pipes. It suits commercial, industrial, and infrastructure drainage systems where pipes of different sizes or materials need a reliable, watertight joint. Furthermore, the flexible EPDM sleeve absorbs minor pipe movement and misalignment, which simplifies installation and reduces stress on the joint over time. For standard equal-diameter drain connections, see our Standard Rubber Drain Couplings. For heavy-duty shear-banded options, see our Shear Banded Drain Couplings.

Key Features

• EPDM rubber sleeve — Resists weathering, chemicals, and temperature extremes. Consequently, this coupling gives long-lasting performance in buried and exposed drainage installations alike.
• Grade 1 304 stainless steel clamp bands — Heavy-duty bands create a reliable, airtight, and watertight seal. Moreover, stainless steel resists corrosion in wet and aggressive ground conditions.
• Multi-material compatibility — Connects PVC, clay, concrete, and cast iron pipes without adaptor rings or specialist tools. Therefore, it suits repair and upgrade work on mixed-material drainage systems.
• Flexible design — Absorbs minor pipe movement and angular misalignment. As a result, installation is straightforward even where pipes are not perfectly aligned.
• Fast installation — Fits using standard tools with no specialist equipment required. Overall, this reduces labour time and keeps installation costs low on site.
