Installed an under sink water filter with filtered water faucet yesterday, and had to make up this little beauty...
The faucet needed a 1/4" compression fitting.
And the filter output was a 3/8" tube.
Why can't they standardize these things, or sell a proper reducer?
Every time I install one of these things, I have to make up some crazy fitting. Last time I had to cobble together a 3/8" x 3/8" x 3/8" tee, but now I see they actually carry them in home depot (used to be online only).
