Sioux Chief 660-G2B Mini-Rester Water Hammer Arrester, 1/2" MIP, No-Lead

The Sioux Chief 660-G2B Mini-Rester is a compact, no-lead water hammer arrester built for residential single-fixture rough-in applications where a plumber needs to quiet pipe shock without adding bulk behind the wall. It terminates in a 1/2" MSWT (male sweat) connection that is compatible with press-fitting systems and all push-fitting systems, giving installers flexibility on how they tie it into the supply line. The unit is sized AA per the ASSE 1010 standard, the industry benchmark for water hammer arrester performance, so contractors can spec it with confidence that it meets the recognized sizing designation for the fixture load it is protecting. Because it is rated no-lead, it is appropriate for potable water supply lines feeding washing machines, dishwashers, ice makers, and other single-fixture quick-closing valve applications prone to hammer and hydraulic shock. This bulk-packed unit ships 50 each per case, making it a practical stock item for plumbing contractors and distributors who install these arresters repeatedly across new construction and remodel work.

Key Features

  • Trade Size: 1/2" MSWT male connection sized for single-fixture supply line rough-in.
  • Press & Push-Fit Compatible: The 1/2" MSWT model works with press-fitting systems and all push-fitting systems, simplifying tie-in to copper or other supply tubing without soldering.
  • ASSE 1010 AA Sizing: Sized AA per the ASSE 1010 standard, the recognized method for matching arrester capacity to fixture demand.
  • No-Lead Construction: Manufactured to no-lead specifications for potable water supply applications.

Sioux Chief 660-G2B – Frequently Asked Questions

1) Will one Sioux Chief 660-G2B Mini-Rester protect a washing machine supply line, or do I need a larger arrester?
A single 660-G2B Mini-Rester is sized AA under ASSE 1010, which is the smallest sizing designation and covers one fixture. That is exactly the case for a washing machine, dishwasher, or ice maker supply with a quick-closing solenoid valve. Run one on the hot and one on the cold at the box. If you are trying to quiet a branch serving several fixtures or a flush valve group, step up to a larger ASSE 1010 size rather than stacking AA units.
2) Is the Sioux Chief 660-G2B arrester approved for potable water lines?
It is built to no-lead specifications, so it is appropriate for potable hot and cold supply piping, including the fixture supplies feeding appliances. That matters on inspection: a shock absorber installed on a drinking water line has to be no-lead to pass. The unit is made in the United States.
3) Will the 660-G2B fit inside a 2x4 stud wall behind a washer box?
Yes. The Mini-Rester line is a compact arrester specifically intended for tight stud cavities and single-fixture rough-in points where there is no room for a full-size shock absorber. That is the reason to pick it over a larger bellows or piston unit when the wall is already crowded with the box, the valves, and the drain.
4) Do air chambers work as well as a Sioux Chief Mini-Rester for water hammer?
Capped air chambers eventually waterlog and stop absorbing shock, which is why they are not recognized under ASSE 1010. The 660-G2B is an engineered arrester carrying an ASSE 1010 AA sizing designation, so it can be specified and defended on a drawing or to an inspector in a way a field-built air chamber cannot.
5) How is the Sioux Chief 660-G2B packaged if I want to stock it on the truck?
It comes bulk packed, 50 each per case, which suits a plumbing contractor or distributor installing these repeatedly across new construction and remodel rough-ins. It is not a single retail-carded unit.
