- Simple, tool-free installation: each valve converter installs by inserting directly into the bottom of the pipe—no extra tools or sealants required. Quick push-in connection reduces installation time and risk of cross-threading. - Safe, food-grade material: made from 100% high-quality food grade plastic. Non-toxic, corrosion-resistant, and engineered for long-term use without contaminating water. - Leak-resistant and durable: designed for a secure fit and repeated use. Robust construction resists cracking and leakage under normal operating conditions. - Complete 28-piece set with 7 connector types: includes 28 components grouped into 7 different reverse osmosis water filter fittings to cover common connection needs for RO systems and related appliances. A practical kit for repairs, upgrades, or installation projects. - Wide compatibility: made for reverse osmosis (RO) systems and useful with ice makers, water coolers, water dispensers, humidifiers, and other common water-handling appliances. Helps connect or replace fittings between filters, purifiers, and appliances. - Reusable and cost-effective: components can be removed and reinstalled as needed for maintenance or system changes, reducing the need for single-use parts. Typical use scenarios 1) Replace a worn fitting on an under-sink RO filter: swap the old connector with a matching piece from the kit for a fast, leak-free repair without shutting off the entire supply line. 2) Connect an ice maker or water dispenser to a purified water line: use the appropriate converter from the set to create a secure link between the appliance and the RO system. 3) Maintain small humidifiers or coolers: use the kit to replace or adapt tubing connections during routine maintenance or when reconfiguring system layout.
