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.

Key Features

  • Trade Size: 3/4" MHT (male hose thread) connection on one end for standard hose-thread fittings and accessories.
  • Durable Construction: Chrome-plated brass body stands up to repeated connect/disconnect service and resists corrosion at the faucet.
  • Dual-Thread Design: Threaded to mate a faucet aerator connection to a 3/4" MHT fitting in a single adapter, with no extra couplings needed.
  • Flow Rate: Rated to a maximum of 2.2 GPM, in line with standard aerator flow control.
  • Finish: Chrome-plated for a corrosion-resistant surface that matches typical faucet and aerator hardware.
  • Distributor Packaging: Packed 250 per case for supply-house stocking and service-truck resupply.

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.

Sioux Chief 290-21110 – Frequently Asked Questions

1) What does the Sioux Chief 290-21110 aerator adapter actually connect to?
It bridges a faucet aerator thread to a 3/4 inch MHT (male hose thread) connection in one fitting. That lets you tie an aerator-threaded spout into hose-thread supply lines, splitters, or accessories without pulling the faucet spout. Both ends are threaded, so no extra coupling is needed between them.
2) Can I use the 290-21110 to hook a garden hose or portable washer to a kitchen faucet?
That is what the 3/4 inch male hose thread end is for. Standard garden hose and hose-thread accessories (splitters, diverters, faucet-mount filters) thread onto it directly, while the other end mates to the faucet's aerator thread. Flow is capped at 2.2 GPM, in line with the aerator's built-in flow control, so it is a service and utility connection, not a high-volume supply.
3) My faucet spout threads are a different size than a hose bibb. Is this the right part, or do I need a different adapter?
If your faucet spout has standard aerator threads and you want a 3/4 inch hose-thread connection, the 290-21110 is the right single part. If instead you are working at a hose bibb, a laundry box, or a threaded pipe nipple, this is the wrong fitting, since the aerator side will not mate to pipe thread. It is specifically an aerator-thread to 3/4 inch MHT conversion.
4) Will a chrome aerator adapter hold up to being taken on and off repeatedly?
The 290-21110 body is chrome-plated brass rather than plastic, which is why it is specified for repeated connect and disconnect cycles at the faucet. The plating resists corrosion and wipes clean, and brass threads tolerate being wrenched more than a molded fitting. That matters most on service calls and in maintenance settings where the same faucet gets a hose or filter attached over and over.
5) How is the Sioux Chief 290-21110 packaged, and is it sold as a single piece?
Sioux Chief packages the 290-21110 at 250 each per case, which is the format supply houses and distributors stock for service-truck resupply. If you need one or two for a single faucet repair, be aware the manufacturer's pack is a bulk case.
6) Is the Sioux Chief 290-21110 made in the USA?
Yes, Sioux Chief manufactures the 290-21110 in the United States. That is the detail institutional and government buyers usually need for domestic-preference purchasing paperwork.
7) What is the exact part number to order the Sioux Chief dual-thread aerator adapter?
Order it as Sioux Chief 290-21110. That is the manufacturer part number for the chrome-plated brass dual-thread aerator adapter with the 3/4 inch MHT end, and it is the only model in the family.
