Sioux Chief 290-21100 Dual-Thread Chrome-Plated Brass Aerator, 2.2 GPM Max

Sioux Chief 290-21100 Dual-Thread Chrome-Plated Brass Aerator, 2.2 GPM Max

The Sioux Chief 290-21100 is a dual-thread aerator built for faucet spouts that take either a male or a female thread connection, giving plumbers, remodelers, and maintenance techs one part number that covers both rough-in configurations instead of stocking two separate aerators. The body is chrome-plated brass for a durable, corrosion-resistant fit at the spout outlet, and the aerator is rated at 2.2 GPM maximum to control and even out water flow at the tap. It is a straightforward drop-in replacement for a worn or clogged aerator, or a finishing part for a new faucet install, and it works on standard kitchen and bathroom faucet spouts. The 290-21100 is manufactured in the United States and ships 48 pieces per case, making it a practical stock item for service trucks, maintenance shops, and new-construction trim-out kits.

Key Features

• Dual-Thread Design: Fits faucet spouts with either male or female threads, cutting the number of aerator SKUs a plumber needs to carry on the truck or shelve in the shop.
• Durable Construction: Chrome-plated brass body stands up to daily use, resists corrosion, and holds its threads over repeated removal and reinstallation for cleaning.
• Flow Rate: Rated 2.2 GPM maximum, giving consistent, water-conserving performance at the faucet without a weak or splashy stream.
• Finish: Chrome-plated finish matches standard faucet spout hardware for a clean, uniform look at the point of use.
• Serviceable Part: Threads directly into the spout outlet so it can be removed for cleaning or screen replacement without disturbing the faucet body.

Why Sioux Chief?

Sioux Chief builds this aerator from chrome-plated brass for a fitting that holds up to repeated use, cleaning, and reinstallation at the faucet spout, and the dual-thread design means it installs on both male- and female-thread spouts without needing a second part number in inventory. That flexibility, combined with a U.S.-made build and a case pack sized for stocking, makes the 290-21100 a dependable, low-cost way to keep faucet flow consistent at 2.2 GPM maximum during repairs, retrofits, and new installations across residential and light commercial plumbing work.
