Sometimes it can become necessary to maintain the fluid needle packing screw set. You may want to remove it for a thorough cleaning or you may occasionally need to replace the needle packing set. Though it can be a tricky process, our needle packing screwdriver makes it much easier. The tightness of the needle packing screw adjusts how the needle slides within it. You need to have enough tightness to seal around the needle and prevent paint from flowing back into the body from the paint cup area. But, too tight and the needle will not move freely and the main lever will not be able to accurately control the needle movement. The special shape and design of the needle packing screwdriver make it easy to “feel” how tight you are adjusting the needle packing screw on the needle.
