What is the outside diameter of most 3/16 tubing? Specifically interested in the leader lateral line OD.
Is it 1/4-inch or 5/16- inch? Or something else?
Anyone ever use John Guest style push to connect fittings to build a small manifold and connect 3/16 lines to a diaphragm pump (like shurflo or aquatec)? Or is everyone using barb fittings to connect the 3/16 lines?
