Frequently Asked Questions
How does this compare to standard tire plugs?
The KEX-379 provides easier installation due to its built-in pilot wire system, while standard plugs require separate insertion tools. The pull-through design creates a more secure seal when combined with proper tire patches, making it preferred for professional tire repair shops.
What size punctures can this tire repair insert handle?
This 3/8" diameter insert works effectively on most nail holes and similar punctures in passenger car and light truck tires. It's designed for standard nail-sized injuries up to the stem diameter, but won't work for larger tears, sidewall damage, or punctures exceeding 10mm in radial and bias ply tires.
Do I need special cement for installation?
For optimal results, use KEX Part No. 511F flammable tire cement. This specialized adhesive ensures proper bonding between the tire repair insert and patch, creating a permanent seal that prevents future air leaks. Regular rubber cement may not provide adequate adhesion for long-term tire safety and durability.
Can I use these for tubeless tire repairs?
Yes, the KEX-379 tire repair insert is specifically designed for tubeless tire repairs on passenger cars and light trucks. The pull-through design works perfectly with modern tubeless tire construction when used with appropriate patches and proper cement. Not suitable for sidewall damage or punctures near the tire bead area.
