Sioux Chief 290-21110 Dual-Thread Aerator Adapter, 3/4" MHT, Chrome-Plated Brass

Sioux Chief 290-21110 Dual-Thread Aerator Adapter, 3/4" MHT, Chrome-Plated Brass

The Sioux Chief 290-21110 Dual-Thread Aerator Adapter gives plumbers and maintenance techs a quick way to step down from a standard faucet aerator thread to a 3/4" MHT (male hose thread) connection, so an aerator-threaded fixture can be tied into hose-thread supply lines, splitters, or accessories without swapping the faucet spout itself. It is built from chrome-plated brass for corrosion resistance and a durable, easy-to-clean finish, and it is rated to a maximum flow of 2.2 GPM, matching the flow control built into the aerator side of the connection. Because the fitting threads on both ends, one adapter covers both the aerator side and the hose-thread side of the job, cutting down on the number of one-off adapters a service truck has to stock. Sioux Chief manufactures the 290-21110 in the United States and packages it 250 to a case for distributors and plumbing supply houses.

Why Sioux Chief?

Sioux Chief builds the 290-21110 from chrome-plated brass so it holds up to daily connect and disconnect cycles at the faucet without corroding or seizing, and it ships from a United States manufacturing facility. For plumbers and service techs who need to bridge an aerator thread to a 3/4" MHT connection, this adapter is a single, purpose-built part rather than a stack of generic fittings, and the 250-count case packaging keeps supply houses and trucks stocked for routine faucet service and repair work.
