COMBI 2 FOR 1/4 INJURY

All-in-One Dual Seal Integration: This combi unit combines an internal patch repair plate with a dimensional plug stem into a single component. Pulling the stem through the tire fills the puncture path to block external moisture and road debris, while the vulcanizing patch base permanently seals the innerliner to prevent internal air migration into the steel belt packages.

Integrated Lead-Wire Guide Pin: The rubber stem features a pre-attached, rigid metal guide wire that effortlessly steers the unvulcanized repair body through the pre-routed injury channel from the inside out. This design eliminates the need for separate pull-through tools or insertion needles, reducing installation time and preventing stem tearing during placement.

Fully Cushion-Wrapped Stem Compound: The entire length of the 1/4-inch rubber plug is wrapped in a layer of high-tack cushion gum. When combined with chemical vulcanizing fluid, this wrapper creates a continuous cold-vulcanized bond along the internal walls of the tire casing, sealing off the open structural plies.

Tread Area Crown Optimization: The 1-7/8 inch round repair base is structurally engineered to flex along the active tread radius of passenger car and light truck tires. It provides structural reinforcement to the puncture site without causing hard spots, stiff tracking, or wheel balancing irregularities.

Strict Angular Alignment Parameter: Optimized for straight-through tread punctures, this repair unit is calibrated for installation angles under 25 degrees. This ensures even load tracking across the patch plies, giving workshops an accurate benchmark to determine when a clean one-piece or multi-part repair strategy is required.
