Modtek Compression Fittings G1/4" Threads (Black Chrome Finish) (6 Pack, 3/8 to 5/8)

I was thinking maybe these would be a diamond in the rough for the price. But sadly no. Be careful with these. They will tear up your g1/4 threads. They fit. Not well. But they fit. It's to late for me to turn back now. But I would look else ware unless your budget is super small and you have no other choice.(Update)One last thing. For the 3/8id 5/8od size you will not be able to thread the cap over the fitting once the hose in on. I know it suppose to be tight, but this goes beyond tight, it's literally not possible even with wrenches. Maybe it's the hose I'm useing. But primochill lrt, is one of what I think is the most common type to use.Before I said if you have small budget maybe get these. But now I'm gonna say, no matter what your budget is avoid these.
