Product Overview & Official Specifications
The PureSec Inline Shut Off Ball Valve is engineered for 3/8 inch OD tubing, hose, and pipe applications commonly found in reverse osmosis (RO) water purification, residential plumbing, and agricultural irrigation. Constructed from high‑grade polypropylene, the valve offers excellent chemical resistance, UV stability, and long‑term durability, making it suitable for both indoor and outdoor environments.
Its quick‑connect design utilizes a non‑locking clip system that allows users to install or remove the valve with a simple push‑to‑lock action, eliminating the need for wrenches or additional tools. The dual‑port configuration provides a straightforward open‑or‑close function, enabling precise control of water flow and preventing unwanted backflow.
Each valve features a 0.38‑inch inlet and outlet size, compatible with standard 3/8 inch tubing used in most RO systems. The transparent white and blue housing not only adds visual appeal but also helps technicians quickly verify correct orientation during installation.

Complete Buying Guide: Who Should (And Shouldn’t) Buy This
Best for DIY Beginners
If you’re installing a home RO system or a simple garden drip line, the push‑to‑lock action eliminates the learning curve of compression fittings. The low price lets you experiment without fear of waste.
Best for Enthusiast Builders
For hobbyists who like to tinker with multi‑stage filtration rigs, the pack of five gives you spare valves for future expansions or replacements.
Best for Professional Shops
Plumbers and service technicians can keep a handful in their toolboxes for quick swaps on standard 3/8 inch lines, especially when a fast turnaround is required.
ABSOLUTELY NOT RECOMMENDED FOR
- Industrial water‑treatment plants needing >2 bar pressure.
- Fire‑sprinkler or potable‑water systems that require NSF‑certified metal valves.
- Hot‑water recirculation loops above 80 °C.
Frequently Asked Questions
- Can this valve be used with stainless‑steel tubing? Yes, as long as the tubing’s outer diameter matches 3/8 inch (0.38″) and a compatible ferrule is used.
- Is the quick‑connect mechanism reversible? The push‑to‑lock clip can be released by pressing the release tab, allowing removal without tools.
- What is the maximum operating temperature? The valve is rated up to 80 °C; exceeding this may soften the polypropylene.
- Does the valve have a built‑in pressure relief? No, it relies on the internal ball seal; users should install a separate pressure regulator if needed.
- How often should I inspect the clip for wear? For high‑turnover applications, check every 6 months; for occasional use, an annual visual inspection suffices.
- Is the valve NSF‑certified? It is not NSF‑certified; consider a certified metal valve for regulated water systems.
- Can I use this valve in outdoor irrigation? Yes, the polypropylene body is UV‑stable for up to 12 months of direct sunlight.
- What warranty does PureSec offer? The manufacturer provides a 12‑month limited warranty against material defects.
Final Conclusion
The PureSec 3/8 inch Inline Shut Off Ball Valve Pack of 5 delivers on its promise of quick‑connect, tool‑free installation while keeping costs low. Its performance holds up to residential RO pressures, and the five‑valve bundle provides excellent value for DIYers and professionals alike. However, the plastic clip mechanism isn’t built for high‑pressure or fire‑rated applications, so those users should look toward metal alternatives. For most home‑based water‑purification and garden‑irrigation projects, this quick‑connect shut‑off valve is a solid, budget‑friendly choice.
