Fernco AC1922 EPDM Adaptor Coupling 170-192mm to 110-122mm

The Fernco AC1922 EPDM Adaptor Coupling 170-192mm to 110-122mm handles one of the largest pipe size steps in the Fernco AC range. It gives you a strong, airtight, and watertight joint between two pipes of very different outside diameters.

The EPDM rubber sleeve adjusts for minor pipe offset and movement. Furthermore, Grade 1 304 stainless steel bands give a tough, rust-proof grip at both ends. 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 large-bore drainage repair and new-build situations where pipe outside diameters differ significantly.

Applications for the Fernco AC1922 EPDM Adaptor Coupling 170-192mm to 110-122mm

This AC1922 EPDM adaptor coupling suits large-bore drainage repairs, civil drainage installs, and system upgrades where there is a big step-down in pipe outside diameter. In addition, it works well where pipes are made from different materials or are slightly out of line. Moreover, the EPDM body absorbs ground movement and thermal shift without weakening the joint. It therefore takes stress off the nearby pipework on both sides.

The Fernco AC1922 EPDM adaptor coupling also speeds up on-site work. Consequently, you can make a secure, leak-free joint with basic hand tools and no need to cut in new pipe runs.

Technical Specs

This Fernco AC1922 EPDM adaptor coupling uses an EPDM rubber sleeve and Grade 1 304 stainless steel bands. The larger end accepts outside diameters of 170mm to 192mm. However, the smaller end suits outside diameters of 110mm to 122mm. Always measure both pipe outside diameters before ordering.

Selection Advice

Check both pipe outside diameters before ordering this 170-192mm to 110-122mm 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.
