Lubricating chuck coupling - 4 jaws

Lubricating chuck coupling - 4 jaws. Lubrication connectors are designed to connect the hose of the lubrication press and the lubricator when refilling the lubricating grease. Depending on the type of grease nipple, we must select the correct type of connector. For ball-type lubricators, chuck connectors (sometimes also jaw connectors) are used.
