Designed for applications in reverse osmosis, filtration systems, automatic coffee brewers, ice-makers, and the majority of refrigeration hookups, these kits require no tools to install onto existing plumbing in minutes. Each kit includes ¼ in. natural, blue, or white tubing, a ¼-in. angle-stop adapter valve, and a ¼-in. faucet connector. Eliminating the use of a self-piercing valve, these kits are also lead-free and NSF 51 and 61 certified.
