Simple solid piece of tubing with barbs to hold onto the hose
About as simple a product as can get. Piece of tubing machined to correct size. The 1/2-3/8 had good "barbs" for grabbing the inside of the hose on both ends. The 1/4-3/8 had good barbs on 3/8" end but the 1/4" end were somewhat rounded and less defined. I tested both adapters with EPDM hose used for sprayer . Fit fine, not real hard to slip on and satisfactory hold when removing for 1/2-3/8. The 1/4" hose end was slightly easier than 3/8 or 1/2 to install/remove. I would definitely recommend hose clamps on 1/4" ends. I installed proper hose clamps and pressurized lines to 40 psi; both adapters sealed well. The tubing is thicker than some of the cheaper adapter/reducers I've used - like copper ones I've smashed some of those out-of-round. These adapters are much more durable. Very pleased with the 1/2-3/8 adapter purchase. If barbs were as well defined on the 1/4" ends I'd be as happy with them. Overall reasonably happy with these adapters and should work well for many years.

Low Tolerance Connector
This is a low quality, low tolerance connector, and it will not work for high tolerance lines like nylon or rubber fuel injection lines (see photos).On a rubber fuel injection line (high pressure) the barb will cut the inner part of the line and cause a restriction, or flow problem. I needed it for a nylon fuel injection line, and the tolerance is so far off that the 5/16th side of the barb fit the 3/8th nylon line - the 5/16th wouldn't even try to fit. When I used the heat gun to get it on, it split the 5/16th line trying to press on.

1/4 inch not true to size
The 1/4 inch side has barbs too smooth to trust. I was able to easily push it in and remove by hand with no twisting or turning, easily, into a 1/4 I.D. fuel line (Gates 1/4" Barricade Fuel Injection hose). While this product might be useful for other purposes, I would not trust it for any fuel lines, low pressure or high pressure. The 5/16 inch size appears to be the same. I really wanted this to work as I like using stainless steel when I can. I had read others with similar complaints but had to see for myself. Please do not use these for fuel lines.

Perfect solution
I installed a radiator overflow tank on my classic car. It has a metric equivalent to a 1/4" input line, and the radiator has a 5/16" output line. Hence the need for this adapter. For the price of getting one of these mailed to me from the online hardware suppliers; I paid a little bit more and bought 6 of these from Amazon. And there is no "flange" between the 2 different sizes, so when you install both hose sizes, one on each end - they butt right up to each other in the middle. Nice.....

Typical 1/4 inch being too small.
When will it dawn on these people that 6mm is not 1/4 inch. The barbed fitting wiggles in the 1/4 fuel line. The 5/16 side fits fine. I have to check if it's too late t send these back.

Poor machining for my needs
Useless for me. The 1/4" side is machined to small. Tied 1/2 dozen different 1/4" ID hoses and they all slip on to easy. Even with 2 clamps it would leak with even 20psi.

Smaller than 1/4"
3/8" diameter is accurate, but the 1/4" diameter is smaller. Actually approximately 1/16 smaller. So, useless. Beware if tolerances are important.

A must for Fuel Lines
There is no replacement for metal corrosion resistant connectors with fuel lines. The barbs guarantee a secure, leak proof connection.
