American Standard Pc Aerator 55/64 Female - AMS-M922880

It's a 55/64 inch female aerator, so it threads onto a spout with male 55/64-27 external threads. If your spout has threads on the inside instead, you need a male aerator, not this one. Check the spout tip before ordering: female aerator means the threads are inside the aerator housing and it slips over the outside of the spout.

It's the replacement aerator for American Standard Cadet lavatory faucets. On other American Standard lines or other brands, match the thread size and gender at the spout tip before you commit, since aerator threads are not universal across families.

A pressure compensating aerator holds the flow steadier as supply pressure moves around, rather than gushing on a high-pressure riser and dribbling on a low one. In a multi-family or hotel building where pressure varies floor to floor, that's the reason to spec it: the lavatories behave the same on every level. The M922880 is the pressure compensating version for Cadet lavatory faucets.

No. It hand-threads onto the spout, and the only thing that usually slows the job down is a corroded old aerator that needs a strap wrench or aerator key to break loose. Nothing else is required to complete the swap. For property managers doing a whole building, it's a one-person, no-shutoff job at each sink.

It's built for lavatory faucets, specifically the American Standard Cadet line. Kitchen spouts commonly use a different thread size and a higher flow aerator, so this 55/64 female part often won't thread on, and where it does it will restrict flow more than a kitchen sink wants. Keep it on the lavatories.

Polished chrome only, ordered as MPN M922880-0020A. If your Cadet lavatory faucets are brushed nickel or another finish, the visible ring at the spout tip will not match, so weigh that on a front-of-house restroom. Back-of-house and utility lavs, nobody notices.
