A low-cost non-spill connector that eliminates liquid dripping during attachment and detachment! Suitable for ink and medical use too!

CPC's one-touch fittings (couplings) have a lineup of over 18,000 types. Among them, the 'push-button non-spill joint,' which is classified as the world's smallest and lightest (*), is a fitting that contributes to the miniaturization of final products without causing liquid drips during attachment and detachment. It can be attached and detached with one hand in an instant while under pressure, and it minimizes air entry into the line to nearly zero, preventing the solidification and deterioration of inks and other substances. If you are considering cost reduction and weight reduction for stainless steel couplings, we also offer fittings made from super engineering plastic polysulfone. For more details, please download the catalog. You can also view a demonstration at the link below. http://www.youtube.com/watch?v=R55q-mLkXE0 * World's smallest and lightest... as a push-button non-spill fitting with valves on both sides. As of 2019.
