Sioux Chief 660 Mini-Rester AA-Size 1/2" PEX Water Hammer Arrester, No-Lead

The Sioux Chief 660 Mini-Rester is a 1/2" PEX water hammer arrester built for behind-the-wall rough-in on residential single-fixture supply lines. It is available in two PEX connection types — F1807 PEX Crimp or F1960 ProPex Tee — so plumbers can choose the arrester that matches their crew's standard PEX joining method without switching product lines. No-Lead construction and compact AA sizing let the 660 Mini-Rester absorb the pressure surge created when a fast-closing valve or appliance solenoid stops flow, cushioning the shock before it travels down the PEX branch line and stresses fittings, crimp rings, and joints elsewhere in the system. Manufactured in the United States, this Mini-Rester ships 50 EA per carton for repeat single-fixture rough-in work.

Key Features

  • Trade Size: 1/2" connection sized to tie directly into PEX supply lines feeding a single fixture.
  • No-Lead Construction: built to a no-lead specification, appropriate for potable water rough-in applications.
  • Mini-Rester, AA Size: Sioux Chief's compact Mini-Rester design, sized AA for residential single-fixture installations rather than whole-house branch or main lines.
  • Two Connection Options: available as F1807 PEX Crimp or F1960 ProPex Tee, letting plumbers select the connection type that matches their PEX joining method on this listing.
  • Shock Absorption: cushions the pressure spike created by fast-closing valves and appliance solenoids to help prevent water hammer noise and repeated stress on PEX joints.
  • Compact Behind-the-Wall Profile: the Mini-Rester's small body is sized to fit in tight wall cavities and stub-out locations where a full-size arrester will not fit.
  • Point-of-Use Placement: mounts on the PEX branch line ahead of the fixture's stop or appliance connection, inside the wall or below the fixture, reacting to the surge right where it starts.
  • Contractor Packaging: supplied 50 EA per carton for distributors and plumbing contractors stocking single-fixture rough-in jobs.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Residential Single-Fixture Water Supply Lines
  • Behind-the-Wall PEX Rough-In Plumbing
  • New Construction and Remodel Plumbing Projects
  • Point-of-Use Shock Absorption Ahead of Supply Stops
  • Tight Wall Cavities and Stub-Out Locations Needing a Compact Arrester
  • Distributor and Contractor Stock for Repeat Single-Fixture Rough-In Work

Why Sioux Chief?

Sioux Chief builds the Mini-Rester line with no-lead construction and manufactures the 660 Mini-Rester in the United States, giving plumbers a compact, single-fixture water hammer arrester they can install directly into 1/2" PEX rough-in without adding bulk behind the wall. Offering both F1807 PEX Crimp and F1960 ProPex Tee connection options on this listing, Sioux Chief lets contractors match the arrester to their crew's standard PEX joining method without switching product lines. The AA sizing keeps the 660 scaled to a single fixture, so contractors are not oversizing an arrester meant for a whole-house main onto a lavatory, appliance, or fixture branch line. Packed 50 EA per carton, it is built for plumbers and distributors who need a consistent, repeatable single-fixture arrester for new construction and remodel PEX rough-in work.

Sioux Chief 660-X2B – Frequently Asked Questions

1) Is an AA-size water hammer arrester big enough for my application?
AA is the smallest sizing class and the 660 Mini-Rester is built for a single fixture, not a branch or a whole-house main. Use it on a lavatory, a washing machine or dishwasher box, or any one fixture's 1/2 inch PEX supply. If you are trying to control hammer on a multi-fixture branch or at the main, an AA unit is undersized for that job and you want a larger arrester.
2) Where in the rough-in does the 660 Mini-Rester get installed?
It mounts on the 1/2 inch PEX branch line ahead of the fixture stop or appliance connection, either inside the wall cavity or below the fixture. Putting it at the point of use is the point: the surge from a fast-closing solenoid or quarter-turn valve gets absorbed where it starts instead of travelling back down the PEX and working on your crimp rings and fittings.
3) Will a water hammer arrester fit in a shallow stud wall behind a washer box?
That is what the Mini-Rester body is scaled for. The 660 is a compact AA-size unit intended for tight wall cavities and stub-out locations where a full-size arrester will not go in. It is a behind-the-wall rough-in part, so no access panel is needed after close-up.
4) Is the Sioux Chief 660 Mini-Rester OK for potable water lines?
Yes. The 660 Mini-Rester is built to a no-lead specification for potable water rough-in, which is what lets it go on a drinking water supply branch feeding a fixture or appliance.
5) Can I use the 660 Mini-Rester on 1/2 inch copper or CPVC instead of PEX?
No. Both versions of the 660 are PEX-connection arresters, one F1807 crimp and one F1960 ProPex tee. For copper or CPVC you need an arrester with sweat, threaded, or solvent-weld ends instead.
6) How does the Sioux Chief 660 Mini-Rester ship for contractor stock?
Fifty each per carton. That packaging is aimed at plumbers and distributors doing repeat single-fixture rough-in, where you are setting one arrester per fixture across a tract or a multi-family build. It is also made in the United States if that matters on your submittal.
7) Do I need an air chamber or a dead-leg stub if I install a 660 arrester?
No. The 660 Mini-Rester is a sealed, engineered shock absorber that cushions the pressure spike itself, so it replaces the old capped air-chamber approach that waterlogs over time. Set it on the PEX branch at the fixture and you are done; nothing else has to be added to make it work.
