American Standard Aerator Insert 1.5 GPM - AMS-M910271

It's the internal aerator insert for an American Standard faucet, rated at 1.5 GPM. The insert is the screen-and-flow cartridge that drops inside the aerator housing on the faucet spout, so you reuse the existing housing and just swap the insert to restore the spray pattern or bring flow down to 1.5 GPM. Order under MPN M910271-0070A.

If the faucet currently has a 2.2 GPM aerator, yes, swapping in the M910271 insert drops the outlet to 1.5 GPM. That's the common move in multi-family and hospitality retrofits where a water-conservation target is set per fixture. If your faucet is already at 1.5 GPM, this insert simply restores the original rate with a clean screen.

It's a single-part, single-configuration item, MPN M910271-0070A, with no finish or size options to get wrong on a bulk order. That makes it straightforward to stock for maintenance carts where the faucets it fits are already identified. Confirm the part against the model number on the faucets in your building first, since American Standard uses several aerator inserts across its lines.

No finish option applies. The insert sits inside the aerator housing and isn't visible once installed, so it's supplied unfinished. The visible finish on the spout comes from the housing or trim ring you're keeping, not from this part.

Usually not much. The aerator housing unscrews from the spout by hand or with a cloth-wrapped pair of pliers, the old insert lifts out, and the new one drops in with the screen side facing down toward the outlet. Keep the washer that came out with the old insert if the replacement doesn't carry one, or the joint will weep at the spout threads.
