Review on Splice Coupler Connector Fitting Adapter Replacement Parts for Fuel System by Dewey Galyon

Excellent surface finish The edges of the serrations are quite sharp and should provide an excellent grip. Used on my G37 heater hose fitting to replace a z1motorsport exhaust valve that is not stopping the leak. The coupling fits perfectly without squeezing the hose too much. Very happy and reassured to know this is not a standard plastic part that he replaced.
