CellarBrew Splicer Mender Stainless Steel 5/16" Barb x 1/4" Barb Reducing Joiner Union Hose Barb Fitting Air Water Fuel (Pack of 6)

Perfect part excellent delivery

I had to replace the primer bulb on my outboard gas tank which had 1/4" hose. All the primer bulbs are either 5/16 or 3/8. So I bought these & a piece of 3/8 fuel hose at the farm store. All together now & no leaks.

Very well made

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.....

I was going to buy the plastic ones, but why? The stainless looks better (if you can see it), and it will never break! Also MUCH easier to shop for on Amazon than anywhere else! Don't be a cheapskate! Get the stainless!
