Quaturn Cartridge: The Quaturn cartridge was the industries first replaceable, completely self-contained valve cartridge. The cartridge allows the user to turn the water from full flow to off in just a quarter-turn. This unique cartridge was designed to close with the flow of the water rather than against it which reduces washer ware and virtually eliminates faucet drips. Although the Quaturn cartridge has been updated over the years to incorporate new technologies and materials it still holds true to its principals and is completely interchangeable with any Quaturn manufactured since 1913.
