BlackJack has built a reputation and customer base second to no one in the tire repair industry. We manufacture or have manufactured to our specifications a complete line of tire repair supplies, wheel weights, and tire repair tools. Our goal is to produce the best tire repair products possible. When it comes to tire repair we feel if we are faced with a choice of quality over price we will choose quality. However we are pleased to find that we can provide quality and affordability at the same time. We are able to do this because we are both a manufacturing and marketing company with very low corporate overhead. Highest-Grade Materials: BlackJack offers a complete line of tire repair products and supplies. As an example many companies supply valve stems that use an inferior rubber that will crack when exposed to air, ozone, and UV rays. All of our valve stems, hoses, and all rubber products are manufactured with the best EPDM rubber. This is a tougher synthetic rubber and has a much broader temperature range than natural rubber, and remains flexible in the coldest weather. It also resists ozone and chemical attack that deteriorates natural rubber. Product Line: We specialize in tire repair products and we attempt to have everything needed to accommodate your every need. Here is some information about some of the major categories.
