WARNING! Attention to "ACTUAL SIZE" for barb-size 14/32"inch=Premium USA Quality 14/32” Check Valve Posi-Seal Anti-Back Flow=This high performance anti-leak check valve will solve your back-flow problems, install it and forget it! Its high strength super advanced “PTFE” solid ball and a“Viton/FKM”-“O”- Ring encased by a Brass durable body that can withstand operating pressures of up to 200psi and high temperatures of up to 380Degree F. "All time highest ratings in its Class". Perfect solution for conditions in-line where Aluminum and copper create corrosion and contamination conditions that affects or compromises the quality of fluid flowing.Engineered Dynamic Design Called “Max-Flo-Chek” tm.=This design allows for maximum flow in-line, when positive moving fluid flow occurs, the ball moves freely to a center cavity away from sealing “O” ring allowing for maximum flow all around the ball with zero fluid resistance. On an instant, negative or reverse fluid flow occurs, fluid pushes ball back into its posi-seal “O-ring" for a solid stop! In this innovative dynamic design there are no, hinged flaps, screws, springs or diaphragms to restrict flow and/or malfunction. It may be used in vertical or horizontal configuration.Piece Of Mind=With your “I flow check valve” in-line, you can feel confident your boat will stay primed and start in the middle of a lake, keep out any unwanted water from your hull thru your bilge pump. Emergency Generators will keep fuel primed ready at a moments notice to start. Motorcycles, ATVs will stay primed ready to start. Fish Aquariums won't drain in an Elec power loss.Household Domestic Safe =Can be safely used in potable h2o syst, fish aquarium filter pumps, hydronic floor heating sys, recirculating pumps, hydroponics grow pumps, heating fluids, antifreeze fluids, reclaimed H2O and many mild oils/chemicals. All around versatile check valve.

Mostly works
Installed vertically (with flow direction down) using 1/2" PEX in a hot water recycling convection system to prevent backflow. I have observed that the valve will allow a small amount of water to flow backwards if the backflow is gentle enough. Perhaps the ball is heaver than water and so the valve sits in the open position, in a vertical configuration. when there is no or a small backflow. Still, it mostly works so I gave it 4 stars.

Superior Quality
I used this to replace the plastic one that was originally on my travel trailer black tank flush system. Works great. Fits 1/2” pex perfect.

Does not fit 3/8 PEX
It says 3/8 but it is half 1/2 pexActually 7/16 to be exact.
