Bissell Upper Nozzle Gasket Replacement Seal for Carpet Cleaners

Bissell lists this as the upper nozzle gasket for upright carpet cleaners. It closes the gap between the nozzle body and the recovery path, keeping the machine pulling dirty water up through one continuous, sealed channel rather than losing vacuum right at the seam. A gasket like this has one job, but it is a job that fails quietly, since performance drops before anything visibly breaks.

Parts listings catalogue it for the Bissell 1370 PowerSteamer, the 1622, 1623 and 1623-1 PowerSteamer upright carpet cleaners, and the 25A3 ProHeat upright deep cleaner. Gasket size and shape differ across Bissell's carpet cleaner lineup, so match this seal against the one currently on your machine, or check the part diagram, before ordering.

Rubber and foam gaskets harden and shrink with age even sitting untouched, and repeated exposure to hot water and cleaning solution speeds that along on a machine used regularly. A hardened or torn gasket lets air leak in right where it should be sealed, which shows up as weaker pickup at the nozzle and carpet that comes out wetter than it should, even while the pump and motor both test fine.

Press a fingernail into the gasket to check it: a healthy seal still has some give and springs back, while a hardened one stays stiff, often with a crack or flat spot where it meets the housing.
