BitspowerG1/4" to Enhance Multi-Link Fitting for 16mm OD Rigid Tubing, Black Sparkle, 4-Pack

They look great and do what they are supposed to but way to expensive

The pieces each immediately charmed the build team with their quality look , both the tubing and the multi-link fittings for "16mm OD Rigid Tubing". I bought 4 packs of 4 tubes to have spare components rather than waste time and additional shipping costs; however, I'm crushed to find out that the fittings are not even close to the needed specificity. The O=rings that would fit inside the cap on the rod slides, far to loose to hope to protect against leakage. When the fittings and the hose are employed together, the fitting falls off the end as easily as it could want to. perhaps if you have gravity working on your side, u sing straight up/down lengths of the 16mm pipe you could assemble a tragically dangerous but sexy loop. As for horizontally angled connections to res/rad/whatever....prepare for your tube to launch at whatever head the pumps your using employ. As domesticated as I was initially pleased by the aesthetic quality.Contrariwise, if you use the PETG hard tube, the fittings seem to fit; however, it's gross negligence to suggest that they work for the brass/chrome ones, for which you easily spend several times the significant cost.

Works properly as expected!

Best fittings I've used so far, easy to use, no leaks. I will buying BP again.
