Sioux Chief TSX88 Mini-Rester Double Stubout PEX Water Hammer Arrester, Black

The Sioux Chief TSX88 Mini-Rester is a combination water hammer arrester and double PEX stubout, designed to install directly into a tub/shower valve or to serve as a standalone arrester-and-stubout assembly behind the wall. Built in black PEX for rough-in supply lines, this AA-size arrester is sized per the ASSE 1010 standard, giving plumbers a compact way to absorb hydraulic shock at the fixture connection without adding a separate in-line arrester fitting. It is intended for use by licensed plumbers and contractors during rough-in of tub and shower valves where water hammer control and a clean dual stubout are both needed in one part.

Key Features

  • Combination Arrester/Stubout: Installs directly into a tub/shower valve, or functions as a combination water hammer arrester and stub out in one assembly.
  • Double Stubout Configuration: Provides two PEX stubouts from a single mini-rester body, simplifying rough-in at the valve.
  • PEX Construction: Black PEX material suited to behind-the-wall rough-in plumbing applications.
  • AA Size per ASSE 1010: Sized to the AA category of the ASSE 1010 standard for water hammer arresters.
  • Compact Mini-Rester Design: Integrates shock absorption directly at the valve connection, reducing the need for a separate arrester fitting elsewhere in the line.

Manufactured in the United States, this combination arrester and double stubout simplifies tub/shower rough-in by consolidating two functions into a single PEX assembly, helping plumbers work faster behind the wall.

Sioux Chief 660-TSX88 – Frequently Asked Questions

1) What does the Sioux Chief TSX88 Mini-Rester actually do, and do I still need a separate water hammer arrester in the line?
The TSX88 is two parts in one: a water hammer arrester and a double PEX stubout for a tub/shower valve. It absorbs hydraulic shock right at the valve connection, so you don't have to add a separate in-line arrester fitting elsewhere in that branch. It can go directly into the tub/shower valve or be used as a standalone arrester-and-stubout assembly behind the wall.
2) Is the TSX88 Mini-Rester sized to ASSE 1010, and what size class is it?
It is sized to the ASSE 1010 standard for water hammer arresters, in the AA size category. AA is the smallest class in that standard, which is why it suits a single fixture connection like a tub/shower valve rather than a whole branch or riser.
3) Can I use the TSX88 Mini-Rester on something other than a tub/shower valve?
Its intended use is tub and shower valve rough-in and water hammer control at fixture supply connections, in residential and commercial work. Because it is an AA-size arrester, it is scaled for a single fixture connection; for shock control on a larger branch or main you need a correspondingly larger arrester, not this one.
4) What material is the Sioux Chief 660-TSX88 made of, and is it meant to stay behind the wall?
Black PEX, built for behind-the-wall rough-in supply lines. It is a concealed rough-in part for new construction or remodel work at tub and shower valves, not a finished-surface fitting.
5) Does the Mini-Rester TSX88 give me both hot and cold stubouts at the valve?
It is a double stubout configuration, so a single mini-rester body provides two PEX stubouts at the valve, which is how it covers both supplies in one rough-in part.
6) Is the Sioux Chief TSX88 sold individually or by the case?
Packaging is 25 each, so it comes as a contractor carton rather than a single piece. That suits multi-family or tract work where you are roughing in many tub/shower valves on the same job.
7) Is the Sioux Chief Mini-Rester TSX88 made in the USA?
Yes. Country of origin is the United States, which matters if you are buying under domestic-sourcing requirements on a government or institutional job.
8) What is the correct part number to order for the Sioux Chief Mini-Rester double stubout arrester?
Order Sioux Chief model 660-TSX88. That is the black PEX double stubout Mini-Rester, AA size per ASSE 1010.
9) Does the Sioux Chief TSX88 carry a Prop 65 warning?
Yes, a Prop 65 warning applies to the TSX88 Mini-Rester. Worth noting if you are shipping to a California job and need the labeling on file.
