Sioux Chief 660-GTR1B Mini-Rester 3/8" OD Female Compression Water Hammer Arrester, No-Lead

The Sioux Chief 660-GTR1B Mini-Rester is a compact water hammer arrester engineered to absorb pipe shock right at the point of use, rather than relying solely on air chambers elsewhere in the rough-in. It features a 3/8" OD female compression connection that installs directly to supply stops, and it is manufactured to a no-lead (NL) specification for use on potable water supply lines. This Mini-Rester ships in bulk packaging of 25 EA, making it a practical stock item for rough-in plumbing crews handling multiple fixture connections per job, from single service calls to full remodel packages.

Key Features

  • Trade Size: 3/8" OD compression connection sized for direct installation at supply stops.
  • Female Compression Connection: Threads onto the supply stop's compression fitting; do not use pipe dope on the compression threads.
  • No-Lead (NL) Construction: Manufactured to a no-lead specification for use on potable water supply lines.
  • Compact Mini-Rester Design: Installs close to the fixture so shock absorption happens right at the source of water hammer, rather than at a distant air chamber.
  • Direct Supply Stop Installation: No additional adapter fittings required between the arrester and the stop's compression outlet, keeping the connection simple behind the wall or under the fixture.
  • Bulk Packaging: Supplied 25 EA per package, sized for rough-in inventory and multi-fixture jobs rather than single-unit retail sale.

Why Sioux Chief?

Sioux Chief builds the Mini-Rester to a no-lead specification for dependable performance on potable water supply lines, and its compact compression-fitting design lets plumbers add shock protection directly at the supply stop without reworking the rough-in or fishing extra piping for an air chamber. It is a straightforward way to bring point-of-use water hammer protection to fixture supply installations, and the bulk 25 EA packaging keeps crews stocked for job after job without repackaging waste.

Sioux Chief 660-GTR0 – Frequently Asked Questions

1) What size compression connection does the Sioux Chief Mini-Rester water hammer arrester use?
The Mini-Rester comes in two trade sizes: 1/4 inch OD (model 660-GTR0) and 3/8 inch OD (model 660-GTR1B). Both use a female compression connection that threads directly onto the compression outlet of a supply stop, so no adapter fitting is needed between the stop and the arrester.
2) Can I install a Mini-Rester on a potable water supply line?
Yes. The Sioux Chief Mini-Rester is built to a no-lead (NL) specification for use on potable water supply lines, which is why it is used on fixture supply stops for sinks, lavatories, dishwashers and washing machines.
3) Do I need an air chamber if I install a point-of-use water hammer arrester at the stop?
The Mini-Rester is the point-of-use alternative to an air chamber. It absorbs pipe shock right at the fixture connection instead of relying on an air chamber somewhere back in the rough-in, so you can add shock protection to an existing installation without opening the wall or fishing extra piping. On a remodel or a service call where the rough-in is already closed up, that is the practical reason to use one.
4) Which Mini-Rester size do I order for a standard lavatory or toilet supply stop?
Most residential fixture stops run a 3/8 inch OD compression outlet to the fixture riser, which is the 660-GTR1B. The 1/4 inch OD version, 660-GTR0, is the one to pull for smaller outlets such as ice maker and small appliance runs. Match the arrester to the OD stamped on the stop's outlet, not to the inlet pipe size.
5) Will a Mini-Rester stop banging pipes when a washing machine or dishwasher valve shuts?
That is the main use case. Fast-closing solenoid valves on washers and dishwashers are a common source of water hammer, and the Mini-Rester installs on the supply stop feeding the appliance so the shock is absorbed at the source. For a washer you would typically fit one on each of the hot and cold stops.
6) Should I use pipe dope or thread sealant on the Mini-Rester connection?
No. The connection is a female compression thread that mates to the supply stop's compression fitting, and the description is explicit that pipe dope should not be used on those threads. The compression ferrule makes the seal.
7) Is the Mini-Rester sold individually or in a bulk pack?
It ships in bulk packaging of 25 each, which is sized for rough-in crews doing multiple fixture connections per job rather than a single-unit retail purchase. If you are stocking a service truck or running a multi-fixture remodel package, one pack covers the job.
8) Where is the Sioux Chief Mini-Rester made?
The Mini-Rester is manufactured in the United States, which matters on public and institutional work carrying domestic-sourcing requirements.
