We have received a great deal of positive feedback on the effectiveness of our sealant for sealing punctures and preventing pressure loss in tires. These exceptional sealing properties have also been known to seal the valve cores. With this in mind our product lab has developed a proprietary process for treating both the valve stem and valve cores which inhibit clogging in the valves due to the sealant.
Our Black Ox clog protect treatment has been validated to significantly increase the time before the valve cores become clogged with sealant. This will decrease the frequency of maintenance or replacement of valve cores and aid in adjusting the tire air pressure. We are providing this treatment on all valve stem pairs, valve stem kits, and replacement valve cores at no additional cost.
