In addition to using TECH's high-quality repair patches and vulcanizing fluids, the repair process also requires proper tools and a standardized procedure. This ensures that the repaired tire can fully regain its original performance—even after being punctured. The “Uni-Seal” patch, commonly referred to as the Permanent Rubber Plug (PRP) method, seals the injury from both the inside of the tire and through the puncture channel. This creates a strong, airtight bond that allows the tire to be safely used until the tread wears out. Unlike conventional methods that only seal from the inside or outside, TECH’s method prevents repeat leaks from the same puncture. That’s why many tire professionals refer to it as a permanent tire repair.
