Repair or replacement of faucet components, rather than replacement of the entire unit, saves money and resources. Zurn’s single hot metering handle with red index (Part no. G61640) is made for AquaSpec® metering faucets. AquaSpec® faucets contain a unique, heavy-duty quarter-turn ceramic disc cartridge. The cartridge is so durable, you can expect it to last up to one million cycles. When you need a replacement part for repair or maintenance of a faucet, trust Zurn for genuine, reliable parts.
