Professional Tire Repair Patches - KEX KEX-382 Universal Combi-Unit (25-Pack)

Complete Patch and Plug Tire Repair Kit for Radial and Bias-Ply Tires

These universal tire repair patches provide tire patching for punctures up to 10mm (3/8") in radial and bias-ply tires. The KEX-382 combi-unit combines both patch and plug technology in one piece, creating a seal that repairs the tire injury while protecting the inner liner. Each box contains 25 quilled tire patches with 3/8" stems and 1-7/8" round patches.

Key Benefits of These Tire Repair Patches

Dual-Action Repair System - Combines patch and plug functionality in one unit, designed to seal both the puncture wound and reinforce the inner liner. This approach addresses both the external injury and internal tire damage, helping to prevent air leaks and moisture infiltration.

Universal Tire Compatibility - Works on both radial and bias-ply passenger car tires, light trucks, ATVs, and motorcycle tires according to KEX specifications. The all-rubber construction accommodates different tire types and constructions.

All-Rubber Construction - Features non-reinforced rubber composition with quilled stem design that provides flexibility during installation. The material is designed to create a vulcanized bond when used with appropriate cement.

Perfect Applications for Universal Tire Patch Repairs

These tire repair patches are ideal for:

Emergency roadside tire patching for nail and screw punctures.
Professional tire service center repairs and fleet maintenance.
ATV and off-road vehicle tire repairs where durability matters.
Low-pressure tire applications requiring flexible patch materials.
Alternative to tire replacement when punctures are repairable.
Heavy-duty tire repair situations requiring durable, long-lasting repairs when installed per manufacturer guidance.

Frequently Asked Questions

How do combi-unit patches compare to plug-only tire repairs?

Combi-unit patches are designed to provide both inner liner repair and puncture sealing in a single component, creating a repair system that addresses both the external puncture and internal tire damage. Plug-only repairs typically seal the puncture wound but do not address inner liner damage, which may allow moisture infiltration and could lead to gradual failure.

What size punctures can these tire patches repair effectively?

These KEX-382 patches are designed to repair punctures up to 10mm (3/8") in diameter according to manufacturer specifications. The 1-7/8" round patch diameter provides coverage area for typical nail, screw, and debris punctures commonly found in passenger and light truck tires. The patch size is intended to provide adequate sealing surface around the injury area.

Do I need special cement for proper tire patch installation?

Yes, KEX recommends using KEX KX-511F flammable chemical cement during installation to achieve proper adhesion and vulcanization. This cement is specifically formulated to work with KEX patches and creates a chemical bond between the patch material and tire interior. Using the recommended cement helps ensure the repair meets manufacturer specifications for adhesion strength.

Are these patches suitable for tubeless tire repair applications?

Yes, these KEX-382 patches are designed for tubeless radial and bias-ply tires according to manufacturer specifications. The all-rubber construction is engineered to provide flexibility needed for tubeless tire applications while maintaining an airtight seal when properly installed. The patch material is intended to conform to the tire's inner surface during the vulcanization process.
