Quality and correctly sized
Nice construction, used for pond water feature rather than fuel so s tad over engineered for the purpose but I like that. Good fit well made.

Works well on Camaro LT1 opti spark vent system.
Used these 1/4 one ways for my 95 Camaro lt1 opti spark system. My old check valves were sticking open and this was a great upgrade. The back flow is solid and the one way is nice because it has a slight open pressure instead of a free float valve. Easy to install, great price and I like the solid metal design of the housing.
