Review on Steel Tube M10X1 0 Bubble Card by Jeff Pettis

Poor quality. The threads are uneven and cannot be hand tightened into the end of the hose or fitting. At first I thought those inline nuts were the wrong size and ended up threading them in and out of the fitting to loosen the fit so I could thread them by hand. This is particularly problematic when changing the brake hose fitting quickly to prevent fluid leakage in the master cylinder. The coating on this nut is also of poor quality.
