Sioux Chief 660-GTR0B Mini Rester 1/4" OD Female Compression Tee Water Hammer Arrester

The Sioux Chief 660-GTR0B Mini Rester is a compact water hammer arrester built for retrofit installations behind the wall on single-fixture residential supply lines. It installs directly to supply stops using a 1/4" OD female compression tee (FEMCOMP T) connection, making it a quick add-on when a contractor needs to quiet pipe shock on a dishwasher, ice maker, or similar fixture line without opening up the wall. The unit is sized AA per the ASSE 1010 standard, the designation covering individual-fixture water hammer arresters. This bulk-packed Mini Rester ships 25 EA per package for plumbers and distributors stocking rough-in service parts for retrofit and repair calls.

Key Features

  • Trade Size: 1/4" OD compression connection sized for direct installation at a single-fixture supply stop.
  • Connection Type: Female compression tee (FEMCOMP T) fitting installs directly to the supply stop without additional adapters.
  • Retrofit-Ready: Designed to install directly to existing supply stops, making it ideal for any residential, single-fixture retrofit application where the wall cannot be opened.
  • ASSE 1010 Standard: Sized AA per the ASSE 1010 standard for water hammer arresters, the recognized sizing designation for individual-fixture units.
  • Installation Note: Do not use pipe dope on the compression threads — the compression connection is designed to seal without additional sealant, and pipe dope can interfere with proper seating.
  • Bulk Packaging: Packaged 25 EA per carton for plumbing contractors and distributors stocking service and retrofit parts.

Sioux Chief 660-GTR0B – Frequently Asked Questions

1) Will the Sioux Chief 660-GTR0B Mini Rester install directly on an existing angle stop without cutting into the wall?
Yes. The 660-GTR0B is a tee-configured arrester with a 1/4 inch OD female compression connection, so it threads straight onto an existing supply stop and the fixture riser reconnects through the tee. That is the whole point of the Mini Rester: it quiets pipe shock on a single-fixture line without opening the wall, which makes it a service-call part rather than a rough-in part.
2) Do I need pipe dope or thread sealant on a 1/4 inch compression water hammer arrester?
No, and using it can cause a leak. The Mini Rester's compression connection seals by the ferrule compressing against the tube, not by sealant on the threads. Sioux Chief specifically says not to use pipe dope on the compression threads, since it can keep the joint from seating properly. Clean tube, square cut, snug the nut.
3) What does AA size per ASSE 1010 mean on a water hammer arrester, and is it enough for a dishwasher or ice maker line?
AA is the smallest sizing designation in ASSE 1010, the standard that covers water hammer arresters, and it is the size assigned to individual-fixture units. The 660-GTR0B is an AA unit, so it is sized for one fixture: a dishwasher, an ice maker, a lav or a similar single supply line. It is not sized to protect a branch serving multiple fixtures or a whole riser; for that you want a larger ASSE 1010 size installed on the branch.
4) Will the 660-GTR0B work on a 3/8 inch compression supply stop?
No. This one is built for 1/4 inch OD compression tubing, the size typically run to ice makers and some appliance lines. A 3/8 inch outlet stop, which is what most lav and toilet risers use, needs the matching 3/8 inch version of the Mini Rester instead. Confirm the OD of the tube coming off your stop before you order the carton.
5) Is the Sioux Chief Mini Rester sold individually or in bulk?
It comes bulk packed, 25 each per carton. That suits a plumbing contractor stocking a van or a distributor carrying service and retrofit parts, since these get consumed one at a time on repair calls. If you need a single piece for one dishwasher, be aware you are buying a carton quantity.
6) My 1/4 inch supply line is hammering every time the ice maker valve closes. Is a mini arrester the right fix, or do I need a bigger unit?
A single fast-closing solenoid valve on a 1/4 inch line is exactly what the Mini Rester is for. The shock is generated at that one fixture, so arresting it at the stop, right where the 660-GTR0B mounts, is the correct place to absorb it. Step up to a larger ASSE 1010 size only when multiple fixtures on a shared branch are banging, or when the noise persists in piping well upstream of the stop.
7) Are Sioux Chief Mini Resters made in the USA?
Yes, the 660-GTR0B is listed with the United States as country of origin, which matters on public work and institutional jobs carrying domestic sourcing language in the spec.
