American Standard Aerator 2.2 GPM Maximum Flow with 15/16 x 27-in. Male Threads - AMS-A922869

It has 15/16 x 27 male threads, which is the standard large male spout thread on most kitchen and lavatory faucets in North America. Male thread means the aerator threads go on the outside and it screws up into a female spout opening. If your spout has an external thread instead, you need a female aerator, not this one.

Unscrew the existing aerator and look at the spout. If the threads are on the inside of the spout opening (female spout), a male 15/16-27 aerator like this American Standard unit threads in. If the spout has threads on the outside, you need a female aerator, commonly 55/64-27. Measuring across the aerator threads at about 15/16 inch confirms the size.

This aerator flows a maximum of 2.2 GPM, which is a kitchen-faucet flow rate. Public lavatories in most commercial and institutional settings are held to much lower rates, typically 0.5 GPM or 0.35 GPM metered. For multi-family and hospitality kitchens, 2.2 GPM is the usual replacement flow; for a public handwash sink, order a low-flow aerator instead.

Usually yes. A faucet that sprays off to one side, spits, or has dropped off in stream quality almost always has a clogged or damaged aerator screen from scale and debris. Swapping in a replacement aerator, such as this 2.2 GPM American Standard unit with 15/16-27 male threads, restores the stream without touching the cartridge or valve body.

For kitchen sinks, yes. A 2.2 GPM aerator with 15/16-27 male threads is the most common kitchen spout configuration, so one part number can cover a lot of units if the spouts are internally threaded. Check a sample of spouts across each building phase first, since older or imported faucets may use a female thread or a proprietary spray-head insert that no standard aerator fits.

Chrome only, sold as part number A922869-0020A. The visible ring on a 15/16-27 male aerator sits inside the spout opening, so chrome reads as a neutral match under most spouts, but it will not colour-match a brushed nickel or matte black spout if the housing edge is exposed.

Hand-tight is normally enough. The aerator threads directly into the spout; if the old one is scaled in place, wrap the housing in a cloth and use pliers so you do not mar the spout. A replacement aerator of this type includes its own washer or seal seat in the housing, so no separate gasket purchase is needed. Nothing else is required to complete the swap.
