Micro injection flooring repair assembly and method

A micro injection assembly for the repair of floors comprising:

• an adapter body 104 having a first end, a second end opposing the first end of the adapter body, a recessed internal wall surface defining a threaded configuration operably configured to couple with a threaded tube, and defining an internal channel spanning from the first end of the adapter body to the second end of the adapter body;
• a hub 116 selectively removably coupled to the adapter body, having a first end 210 disposed in a directly adjacent configuration with the second end of the adapter body 104, having a second end opposing the first end of the hub, and having a rigid needle member 110 coupled thereto and recessed within the hub, the rigid needle member projecting outwardly from the second end of the hub in a linear orientation, having a blunt distal end 206, and defining a needle channel spanning from the blunt distal end to the first end of the hub, wherein the needle channel is in fluid communication with the internal channel;
• an overall hub-needle length separating the first end of the hub and the distal end of the needle member and a needle member length separating the second end of the hub and the distal end of the needle member, wherein the overall hub-needle length has a length variance ranging from 0.5-1.5 in. relative to the needle member length;
• and
• a cap selectively removably couplable to the adapter body, when the hub is not coupled to the adapter body, in a watertight configuration with the cap disposable in an overlapping configuration with the second end of the adapter body.
