Description
The plug repair units require no special pulling tools. Simply insert the plug into the puncture from the inside of the tire and pull the repair unit through from the outside. Both the stem and the patch are coated with vulcanizing gum to ensure a strong bond on both the inner liner and through the injury. These patches are black with gray vulcanizing gum and can be vulcanized chemically or using a heat curing system.
This single product repairs both the hole and the surface, offering protection against leaks and sealing against moisture.

Instructions
1. REPAIR PROCEDURES FOR COMBINATION UNITS
Before repairing, mark and remove the object causing the puncture. With the tire inflated, apply a soap solution to the damaged area to determine if the air loss is due to one or multiple punctures. Carefully remove the tire from the wheel to avoid further damage and place it on a spreader.
2. PROBING
Probe the puncture to assess its size and direction, ensuring all foreign materials are removed. Do not attempt to repair if the injury exceeds the recommended repair limits.
3. INTERNAL EXAMINATION
Spread the tire beads and mark the damaged area with a crayon. Inspect the tire carefully to confirm that the damage is within acceptable repair limits. If the limits are exceeded, do not proceed with the repair.
4. REPAIR UNIT SELECTION
If the injury is 1/4'' (6mm) or smaller and the angle does not exceed 25 degrees, a combination repair unit is the best option. Reinforced Combination Units are suitable for tread areas only, while Universal and Lead-Wire Combination Units can be used in any repairable area.
5. CLEANING
Use a buffing solution and an inner scraper to clean an area slightly larger than the patch head of the repair unit. This ensures the removal of dirt and mold lubricants, improving adhesion.
6. BUFFING
Buff the repair area with a buffing wheel to create a textured surface, being careful not to damage the inner liner. Use an appropriate reamer or cutter (for lead-wire units) to drill the injury channel from both the inside and outside, removing damaged cables and debris. Vacuum away any buffing dust.
7. CEMENTING
Apply vulcanizing cement to the injury channel and the prepared repair area. Work the cement into the rubber thoroughly. Avoid puddling or scraping. Allow the cement to dry completely before proceeding.
8. INSERTION
Remove the backing from the patch head (and the stem for lead-wire units). Avoid touching the gum surface. Push the quill or lead wire into the injury from the inside and pull it through using pliers. Continue until the patch head is firmly seated against the inner liner.
9. FINISH REPAIR
Stitch the patch bead to the inner liner, starting from the center and working outward to eliminate any trapped air. Cut the stem 1/8'' above the tread surface. Apply Inner Liner Sealer to the overbuffed area and allow it to dry.
