Pipe Adaptor, 1-3/4" White, Fits Oversize Kenmore Central Vac Pipe

Kenmore built some central vacuum runs on 1-3/4 inch outside-diameter pipe instead of the 2-inch stock that became the industry standard, and this white adaptor bridges that gap so the older 1-3/4 inch pipe end can accept standard fittings. Without it, a standard coupling or tee will not seat tight enough to hold suction on that non-standard run.

The fitting slides over the 1.75 inch Kenmore pipe and presents a true 2-inch opening at the other end, so any standard central vacuum coupling, inlet valve, or tee joins on cleanly from there. That clean transition is what keeps the joint airtight and the system's suction where it should be, rather than leaking air through a gap the width of a few thousandths of an inch that a mismatched pipe size can leave behind.

Confirm the outer pipe diameter before ordering, since this adaptor is built specifically for 1-3/4 inch Kenmore pipe and will not fit standard 2-inch stock or a different brand's non-standard tubing. It shows up most often when a technician is repairing or extending an older Kenmore central vacuum run with newer, standard-size parts, since new fittings and inlets are made to the 2-inch industry standard rather than Kenmore's older dimension.

Dry-fit before cementing to confirm the pipe seats fully into the adaptor with even contact around the full circumference, and clean any loose dust or old cement residue off the pipe end so the fit is not thrown off by debris in the joint.
