Repair or replacement of faucet components, rather than replacement of the entire unit, saves money and resources. Zurn’s single metering handle with red, blue, and black index plugs (Part no. G60522) is made for AquaSpec® metering faucets and can be used for hot, cold, or single-control 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.
