Rated 5 out of 5 stars.
Need to stop backflow in your air or fluid lines? These simple one-way check valves do just the job. This pack comes with three clear plastic valves with 1/4\ barbed fittings—perfect for tubing in air compressors, aquariums, water systems, fuel lines, or even DIY projects. They only allow flow in one direction (follow the arrow marked on the valve), preventing water, air, or gas from flowing backward and causing problems. Made from sturdy, ozone-resistant plastic with nickel-plated connections for durability. Each valve is about 44.8mm long (1.76\) with barb diameters of roughly 7.85mm and 6mm. You can install them vertically or horizontally, and they're super easy to connect—just push your tubing onto the barbs. A handy, inexpensive solution for keeping your pneumatic or fluid systems running correctly.
