Abstract
A "direct connection" fitting for co-axial outlets from an Injection Lubricator simultaneously engaging external air passage and internal lubricating oil passage outlets by the simple expedient of engaging an outer male and female threaded connection between the Injection Lubricator and any of several alternative fittings, thereby eliminating previously required preliminary internal flexible tube connections for the internal oil passage.
