Barrow Replacement G1/4" O Ring - 10pcs - Green (OG-1410)

I got these thinking they were going to be UV reactive. I did not expect them to be glow in the dark. They are very UV reactive and they are glow in the dark. I know I'm being a big kid here but that's just cool. They're also high quality O-rings. I'm glad I got extras.

They do the job without being too squishy. My last ones (different brand) would squish out and lose their seal if you tightened them enough to be confident the fitting wasn't going to back out.

Excellent
