The Wago brand wire connectors are great. I have used their industrial terminals since '92 and NEVER had a failure due to design or manufacturing, only user error. Like circuit ampacity too high for rated terminal or not installing wires properly. Of course another excellent build Dennis! Have not made the leap to hydraulics, the fear of an oily mess is my main inhibition. Did you have many leaks to chase down? Do they make a push to connect fitting that small? I guess if they did you may have used them. Threaded fittings are so tidious.
