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. 59517006) 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 short, 2 1/8-inch cartridge is for quarter-turn faucets with an exposed chrome cartridge retaining nut. It's intended for the hot-water handle on the left, opening counterclockwise (closes clockwise). When you need a replacement part for repair or maintenance of a faucet, trust Zurn for genuine, reliable parts. Size: xl. Color: Rough Brass.
