Quick Connect Fittings for RO Systems
Quick connect fittings are essential for reverse osmosis (RO) systems, water filters, and under-sink installations. Designed for fast, leak-proof connections without tools, they simplify water system maintenance and improve long-term reliability.
Multiple Sizes for Every Application
We carry a complete range of quick connect sizes, including 1/4", 3/8", and 1/2" tubing connections. Choose from straight connectors, elbows, tees, valves, and adapters to match your system’s configuration. All fittings are made from durable, food-grade materials for safe drinking water use.
Why Use Push-to-Connect Fittings?
Push-to-connect fittings reduce installation time, eliminate the need for clamps or adhesives, and provide long-lasting water-tight seals. They're perfect for both DIY installations and professional setups. Whether you're replacing a worn fitting or upgrading an entire RO system, these components offer a hassle-free solution.
