This lead free HydroGuard under the counter combination tempering valve for low flow control is designed for lavatory applications where the temperature of hot water must be controlled for safe, economic use. An advanced thermal actuator quickly senses and compensates for outlet temperature fluctuations induced by water temperature and pressure changes in the supply line. It features a rough bronze finish, 3/8 in. compression connections, corrosion resistant internal components, integral checks to prevent cross flow, and inlet screens to filter out debris. The temperature adjustment stem is simple to adjust and has a locking nut to prevent unauthorized or accidental adjustment. Factory temperature is set at 105 degree F (40.6 degree C).

• Solid brass construction enhances durability
• Corrosion resistant internal components for extended life
• Advanced thermal actuator improves performance
• Adjustable temperature selection with locknut to prevent tampering
• Temperature control to ASSE 1070, down to 0.5 GPM
• Integral checks with screens prevents cross flow
• Factory temperature is set at 105 degree F (40.6 degree C)

Repair or replacement of faucet components, rather than replacement of the entire unit, saves money and resources. Made of lead-free, heavy-duty cast brass, Zurn's quarter-turn ceramic disc cartridge for AquaSpec faucets (Part no. 59517007) stops leaks that originate from the handle. The ceramic disc cartridge is so durable, you can expect it to last up to one million cycles. This long, 2 7/8-inch cartridge is for quarter-turn faucets with an escutcheon covering the cartridge retaining nut. It's intended for the cold-water handle on the right, opening clockwise (closes counterclockwise). When you need a replacement part for repair or maintenance of a faucet, trust Zurn for genuine, reliable parts.

• Pre-assembled for easy installation
• Fits AquaSpec cold-water handles-opens clockwise/closes counterclockwise
• Long, 2 7/8 in. stem for faucet handles with a covered retaining nut (not for Zurn faucets with exposed retaining nut)
• Lead-free cast brass provides durability while complying with the Safe Water Drinking Act
• Positive shutoff eliminates drips and leakage to save water without over-turning the handles
• Square broach allows handles to align perfectly
• Interchangeable with other manufacturer's parts
• Chicago part no. 377-XTRHJKABNF and T&S no. 011277-45
• Limited lifetime warranty

This 3/4 in. HydroGuard lead free under the counter thermostatic tempering valve is designed for lavatory applications where the temperature of hot water must be controlled for safe, economic use. It features a rugged brass body, union NPT female connections, lock-in handle mechanism, paraffin-based actuator, and integral check valves with inlet screens to prevent cross-flow and contamination. The thermostatic element ensures optimal, consistent performance over a wide range of temperatures. The temperature operating range is 80 to 120 degree F (27 to 49 degree C) and the maximum operating pressure is 125 psi (862 kPa).
