Sioux Chief 660-GTX2B MINI-RESTER 1/2" F1807 PEX Tee Water Hammer Arrester, No-Lead

The Sioux Chief 660-GTX2B MINI-RESTER is a compact, in-line water hammer arrester built to install directly into a PEX tube run at a 1/2" F1807 PEX tee connection. It is engineered for any residential single-fixture application with PEX tube, absorbing the hydraulic shock created when a fixture valve closes quickly so the branch line does not bang against the wall framing. The unit is No-Lead (NL) rated and finished in black, and it is manufactured in the United States. Because it mounts inline on the tee itself, it installs behind the wall during rough-in, right at the fixture stub-out, with no extra fittings or wall space required, which keeps the branch compact for tight stud bays and helps prevent repeat noise complaints on single-fixture supply runs after the wall is closed up.

Key Features

  • Trade Size: 1/2" connection sized for single-fixture PEX branch lines.
  • PEX Tee Connection: F1807 crimp-style tee fitting allows the arrester to be installed in-line on PEX tube during rough-in.
  • No-Lead Construction: NL-rated for installations that require lead-free rough-in components.
  • Compact MINI-RESTER Design: Sized to fit behind the wall at a single fixture stub-out without additional fittings or extra wall cavity space.
  • Black Finish: BLK housing.
  • Single-Fixture Application: Intended for any residential single-fixture application with PEX tube.
  • Rough-In Ready: Installs inline on the PEX tee before the wall is closed, so no access panel or future retrofit is needed.

Why Sioux Chief?

Sioux Chief builds the MINI-RESTER line as a compact, in-line answer to water hammer at individual fixture branches, using No-Lead construction and a 1/2" F1807 PEX tee connection that matches standard rough-in PEX tube. Manufactured in the United States, this arrester is sized to solve hydraulic shock at the single-fixture level without adding bulk behind the wall, so plumbers can spec it on a standard PEX branch without redesigning the rough-in layout. For contractors standardizing on PEX rough-in, the 660-GTX2B gives you a lead-free component sized specifically for single-fixture branch lines, shipped 25 EA per case for stocking multiple jobs at once.

Sioux Chief 660-GTX2B – Frequently Asked Questions

1) Will the Sioux Chief 660-GTX2B connect to 1/2 inch PEX crimp fittings?
Yes. The 660-GTX2B MINI-RESTER has a 1/2 inch F1807 PEX tee connection, so it crimps onto standard 1/2 inch PEX tube with copper crimp rings the same way any other F1807 insert fitting does. If your rough-in uses 1/2 inch PEX with F1807 crimp fittings, it drops right into the branch run.
2) Can I use the 660-GTX2B water hammer arrester on more than one fixture?
No. The MINI-RESTER 660-GTX2B is sized for a single residential fixture branch on PEX tube. If you are trying to quiet a group of fixtures, a battery of flush valves, or a whole main, this is the wrong size part and you want a larger multi-fixture arrester instead.
3) Will this fix banging pipes in an existing finished wall?
Not without opening the wall. The 660-GTX2B is a tee fitting that has to be crimped into the PEX line itself, so it is a rough-in part for new construction or a remodel where the branch is exposed. For noise in a wall that is already closed, you need an arrester you can add at an accessible point such as a fixture stop or an exposed supply connection.
4) Does a water hammer arrester like this need an access panel after the wall is closed?
No access panel is needed. The 660-GTX2B installs inline on the PEX tee at the fixture stub-out during rough-in, and it is built to sit behind the wall permanently without extra fittings or added cavity space, which is what makes it workable in a tight stud bay.
5) Is the Sioux Chief 660-GTX2B lead free for potable water rough-in?
It is No-Lead (NL) rated construction, which is what inspectors look for on potable water rough-in components. The housing is black.
6) How many 660-GTX2B arresters come in a case?
Packaging is 25 each per case, which is how contractors stocking several PEX rough-ins at once buy them. It is made in the United States.
7) What does a water hammer arrester actually do on a fixture branch?
When a fixture valve snaps shut, the moving column of water stops abruptly and the shock wave kicks the branch line against the framing. The MINI-RESTER absorbs that hydraulic shock at the fixture, so the line does not bang. On a single-fixture PEX branch it is the usual cure for repeat noise complaints.
