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

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.
