Sioux Chief sc-660-gtr0 Mini-rester Water Hammer Arrestor

Product Description

The SIOUX CHIEF sc-660-gtr0 is a Mini-Rester water hammer arrestor designed to absorb pressure surges and eliminate the banging noise caused by water hammer in supply lines. It connects via a 1/4-inch OD female compression tee fitting, making it a direct inline installation without the need for separate fittings. Licensed plumbers and HVAC technicians install this type of device wherever fast-acting solenoid valves, dishwashers, washing machines, ice makers, or similar appliances create sudden line pressure spikes.

This arrestor is suited for residential and light commercial plumbing systems where 1/4-inch OD compression connections are present. Typical installation points include under-sink supply lines, refrigerator ice maker connections, and other small-diameter appliance supply runs. The clamshell packaging indicates retail or trade-counter distribution, making it convenient for service calls and small-job inventory.

Key Features

• Mini-Rester design absorbs hydraulic shock from fast-closing valves and solenoids
• 1/4-inch OD female compression tee connection for direct inline installation
• No lead (NL) compliant construction meets safe drinking water requirements

Compatibility

Designed as an OEM-style replacement and new-installation water hammer arrestor for residential and light commercial plumbing systems using 1/4-inch OD compression tee supply connections.

Installation Notes

Installation is performed by a licensed plumber. Shut off the water supply and relieve line pressure before disconnecting any existing fittings. The compression tee fitting should be hand-tightened and then snugged with a wrench — do not overtighten compression fittings as this can crack the ferrule or fitting body. Installation must comply with local plumbing codes and applicable IPC standards.
