The DAA Primer-Tube Cap is a custom made silicon rubber end-cap designed to fit on the 8mm primer tubes used by most reloaders.
If you use any kind of rapid-fill device to load your primers tubes, such as the DAA Primer-Pro, or other auto/semi-auto primer fillers, you are familiar with the issue of full primer tubes tipping over and spilling primers all over the place. These easy-on, easy-off caps will solve that hassle for you. Slide the cap onto the end of the tube, and lay it down flat on its side, never worrying about spilling primers again.
Sold in a handy pack of 5 pcs.
