Fernco AC1221 EPDM Adaptor Coupling 110-122mm to 80-95mm

The Fernco AC1221 EPDM Adaptor Coupling 110-122mm to 80-95mm connects drainage pipes of different outside diameters with a secure, airtight, and watertight seal. The extended EPDM rubber sleeve also helps where pipes are slightly offset, so you get a reliable joint even in awkward conditions. Furthermore, Grade 1 304 stainless steel clamp bands hold firm in buried and exposed use. For the full range, see our EPDM Pipe Adaptor Couplings collection.

This coupling suits PVC, clay, concrete, and cast iron pipes. Consequently, it works well across a wide range of drainage repair, upgrade, and new-build situations where pipe sizes differ.

Applications for the Fernco AC1221 EPDM Adaptor Coupling 110-122mm to 80-95mm

This AC1221 EPDM adaptor coupling suits drainage repairs, system upgrades, and new installs where the two pipes differ in outside diameter. In addition, the extended sleeve helps where there is a slight offset between the pipe runs. Moreover, the EPDM body absorbs ground movement and thermal shift without weakening the seal. It therefore works well in both domestic and commercial drainage systems.

The Fernco AC1221 EPDM adaptor coupling also speeds up on-site work. Consequently, you can complete a secure joint with standard hand tools and no need to cut in new pipework.

Technical Specs

This Fernco AC1221 EPDM adaptor coupling uses an extended EPDM rubber sleeve and Grade 1 304 stainless steel clamp bands. The larger end accepts outside diameters of 110mm to 122mm. However, the smaller end suits outside diameters of 80mm to 95mm. Always measure both pipe outside diameters before ordering.

Selection Advice

Check both pipe outside diameters before ordering this 110-122mm to 80-95mm Fernco EPDM adaptor coupling. As a result, you get a tight, leak-free fit without reducers or extra parts. If your pipe sizes fall outside this range, see the full EPDM Pipe Adaptor Couplings range for other size options.
