Sioux Chief 660-GTC Mini-Rester 1/4" OD Compression Water Hammer Arrester

The Sioux Chief 660-GTC MINI-RESTER is a compact water hammer arrester built for rough-in installation directly at a single-fixture supply connection. It uses a 1/4" OD compression connection that ties in-line behind the wall or under the fixture, and the family is available in Straight and Tee configurations so a plumber can match the arrester to the layout of the supply run being protected — whether the run calls for an in-line compression fitting or a compression tee. Construction is no-lead (NL) for potable water supply, and the arrester is intended for any residential single-fixture application. Because the MINI-RESTER connects directly at the compression fitting in either configuration, a plumber can add hydraulic shock protection at the point of use without cutting in a separate branch fitting or dedicated air chamber. It ships in bulk 25 EA packaging, making it an easy add to a rough-in supply run or service van stock.

Key Features

  • Trade Size: 1/4" OD compression connection sized for direct installation at a single fixture supply stop.
  • Straight or Tee Configuration: Available as a straight in-line compression fitting or as a compression tee, simplifying rough-in behind the fixture without requiring a separate branch fitting in either configuration.
  • Compact Mini Body: The MINI-RESTER's small compression body fits tight spaces behind fixtures where a full-size arrester will not.
  • No-Lead (NL) Construction: Manufactured to no-lead specification for potable water supply lines.
  • Installation Note: Do not use pipe dope on the compression threads.
  • Intended Use: Designed for any residential single-fixture application.
  • Bulk Packaging: Supplied 25 EA per pack for contractor and rough-in stock.

Sioux Chief 660-GTC0 – Frequently Asked Questions

1) Will the Sioux Chief Mini-Rester fit a 1/4 inch OD compression supply line at a fixture stop?
Yes. The Mini-Rester is built for a 1/4 inch OD compression connection, which is the standard supply tube size feeding a toilet fill valve or a lav faucet riser. It ties in right at the fixture supply stop, so you do not have to cut a separate branch fitting or build a dedicated air chamber into the wall.
2) Can a water hammer arrester be installed on a potable drinking water line?
The Mini-Rester is made to no-lead (NL) specification, so it is intended for potable water supply lines. That covers lav, toilet, and kitchen supply connections on the drinking water side.
3) Is the Mini-Rester suitable for a whole-house or multi-fixture application?
No. The Mini-Rester is sized for a single fixture at the point of use, on residential supply lines. If you are trying to quiet hammer on a branch serving several fixtures, a quick-closing solenoid valve on a commercial appliance, or a main run, you need a full-size arrester sized for that branch rather than this 1/4 inch compression unit.
4) Can I add the Mini-Rester to an existing fixture supply without reworking the line?
Yes, that is the retrofit case it is built for. Because it threads onto the 1/4 inch OD compression connection at the stop, you shut off the stop, pull the riser, install the arrester, and reconnect. No wall opening, no soldering, no new branch fitting.
5) Will a water hammer arrester fit behind a toilet or in a tight lav cabinet?
That is what the Mini-Rester's compact body is for. It mounts on the compression connection itself, so it fits tight rough-in clearances behind fixtures where a full-size arrester will not go.
6) Do I need pipe dope or thread sealant to install the Mini-Rester?
No, and do not use it. Sioux Chief specifies no pipe dope on the compression threads. A compression joint seals on the ferrule against the tube, not on the thread, so dope only contaminates the seat. Snug the nut and check for weeping under pressure.
7) How many Mini-Resters come in a pack?
They ship in bulk, 25 each per pack, which is how rough-in crews and service vans usually stock them. Worth knowing if you only need one or two for a single repair, since the packaging is set up for volume rough-in work.
8) Where is the Sioux Chief Mini-Rester made?
United States. That matters on public and institutional jobs carrying domestic-sourcing requirements for plumbing products.
