Fernco AC1703 EPDM Adaptor Coupling 155-170mm to 130-145mm

The Fernco AC1703 EPDM Adaptor Coupling 155-170mm to 130-145mm joins two large-bore drainage pipes with a modest step-down in outside diameter and a firm, airtight, and watertight seal. The EPDM rubber sleeve adjusts for minor pipe offset and ground movement at both ends. Furthermore, Grade 1 304 stainless steel bands give a strong, rust-proof grip. For the full range, see our EPDM Pipe Adaptor Couplings collection.

This coupling suits PVC, clay, concrete, and cast iron drainage pipes. Consequently, it works well in large-bore drainage repairs, system upgrades, and new installs where pipe outside diameters are close but do not match.

Applications for the Fernco AC1703 EPDM Adaptor Coupling 155-170mm to 130-145mm

This AC1703 EPDM adaptor coupling suits large-bore drainage repairs and new installs where the two pipes are close in outside diameter but do not match. In addition, it works well where pipes are made from different materials or are slightly out of line. Moreover, the EPDM sleeve absorbs ground movement and thermal shift without breaking the joint. It therefore takes stress off the nearby pipework on both sides.

The Fernco AC1703 EPDM adaptor coupling also keeps large-bore work moving on site. Consequently, you can make a secure, leak-free joint with standard hand tools and no need to cut in new pipe runs.

Technical Specs

This Fernco AC1703 EPDM adaptor coupling uses an EPDM rubber sleeve and Grade 1 304 stainless steel bands. The larger end accepts outside diameters of 155mm to 170mm. However, the smaller end suits outside diameters of 130mm to 145mm. Always measure both pipe outside diameters before ordering to confirm the fit.

Selection Advice

Check both pipe outside diameters before ordering this 155-170mm to 130-145mm 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.
