Barrow G1/4" to 12mm Hard Tubing Compression Fitting, Gold, 4-Pack

These were easy to use. I was worried they might be cheaply made or something. The tubes seem to slip in and out easier than other fittings but in the end I didn't have a single drip. I'd definitely use these again. I used Barrow 12mm tubes for my build.YouTube: customgtpPC name: Zombie Hunter

I received V4 fittings instead of the ordered V2, so the profile is different (taller with smooth stripe) on the compression sleeve. I actually like these V4 fittings better, since they have 4 O-rings. Replacing all of the V2's in my loop with V4. Happy accident. Cheers.
