Review on Splice Coupler Connector Fitting Adapter Replacement Parts and Fuel System by Victor Shepherd

I bought the 1/2" size and it was too loose in the 1/2" tube for a secure fit without fuel spills. It is described as being rated for fuel use, but the fit is very loose compared to other 1/2" fittings on the same 1/2" hose that I didn't feel comfortable with. I was able to easily remove the notch once fully inserted into the pipe while the other fittings would hold even without the clamps.
