Sioux Chief 660-GTR0 Mini-Rester 1/4" OD Female Compression No-Lead Water Hammer Arrester

Sioux Chief 660-GTR0 Mini-Rester 1/4" OD Female Compression No-Lead Water Hammer Arrester

The Sioux Chief 660-GTR0 Mini-Rester is a compact water hammer arrester for 1/4" OD supply lines, using a female compression (FEMCOMP) connection that installs directly to a supply stop. The tee-clamp body lets a plumber add point-of-use shock absorption at the fixture without cutting into the line, sweating a joint, or adding extra fittings, and it is manufactured to no-lead (NL) specifications. This mini arrester is sized for tight spaces behind sinks, toilets, dishwashers, and other quick-closing valve locations where water hammer needs to be controlled close to the source rather than at a central manifold.

Key Features

• Trade Size: 1/4" OD connection sized for direct installation on standard supply stops.
• Female Compression Connection: FEMCOMP fitting threads onto the supply stop's compression outlet without additional adapters.
• Tee-Clamp Mount: Clamps onto the fitting for a compact, mini-profile installation in tight under-fixture spaces.
• No-Lead (NL) Construction: Manufactured to no-lead specifications.
• Installation Note: Do not use pipe dope on the compression threads; the arrester installs directly to the supply stop without additional sealant.
• Mini-Rester Design: Compact form factor absorbs water hammer shock at the point of use rather than at a central location.

Why Sioux Chief?

Sioux Chief builds the 660-GTR0 Mini-Rester with a no-lead (NL) compression fitting and a compact tee-clamp body so it installs directly to a supply stop without extra adapters or sealant. For plumbers who need to add point-of-use hammer arrestance in a tight supply line without reworking the rough-in, the Mini-Rester's small footprint and direct-to-stop connection make it a straightforward add at the fixture, and the manufacturer's instruction sheet covers the compression connection in detail for a proper, drip-free seal.
