Bitspower Touchaqua G1/4" Dual O-Ring Tighten Fitting for 12mm OD Hard Tubing (for Use with Bitspower Rigid Tubing Only), Glorious Silver, 4-Pack

I've been an EK fan for quite a while now. My PC is using, well, was using 100% EK products until someone recommended I tried Bitspower fittings, and oh my, they do not disappoint! I will never go back to EK fittings! The ease of installing the tubes into these is wonderful, and the dual o-rings provide a bit more leak protection. These come with a thicker outer o-ring too compared to most other brands fittings, allowing for more of a snug fit around the tubing. I highly recommend these fittings!
