Blackjack 4" Tire Plug 60-Pack — 4-inch Black Self-Vulcanizing Butyl Plugs, Heavy-Duty Repair

Blackjack 4" Black Tire Plug (60 Pack) are large-diameter, self-vulcanizing butyl repair plugs designed to restore punctured tires quickly and blend with the tire's black finish.

These tire plugs are formulated from a butyl rubber elastomer compound reinforced with high-tensile fibers and carbon black for improved strength and color matching. Sold in a 60-count pack, each 4-inch plug is intended for larger punctures and is compatible with standard insert-type tire plug tools. The self-vulcanizing property allows the plug to adhere to the rubber around the puncture, creating a durable seal without curing time under most conditions.

What makes the Blackjack 4" plug different from standard tire plugs?

The Blackjack plug is built from a blend of butyl rubber elastomers plus high-tensile fibers to add tear resistance and structural integrity. Carbon black is included to help the plug visually match the tire and increase UV resistance. These elements combine to form a plug that aims to perform reliably for road repairs.

• Butyl rubber base for flexibility and sealing performance
• High-tensile fibers for strength where pressure and movement occur
• Carbon black for color matching and added durability
• Self-vulcanizing formulation that bonds to tire rubber

How do I use the 4" Blackjack plug on a punctured tire?

Usage follows common insert-plug repair steps: locate the puncture, prepare the hole with a reamer, then insert the plug with a compatible insertion tool so the plug spans the breach. Trim any excess that protrudes past the tread once the plug seats. Always inspect and test the repair for air retention and consider professional inspection for sidewall or large-diameter damage.

• Ream and clean the puncture before plugging
• Insert plug using a standard insertion tool until seated
• Trim excess plug flush with tread after insertion
• Check for leaks and re-inflate to recommended pressure

Are these plugs suitable for all tire types and locations?

The 4" Blackjack plugs are primarily intended for tread-area punctures in passenger, light-truck, and some commercial tires where an insert-style repair is appropriate. They are not recommended for sidewall damage or punctures larger than the plug's capacity. Follow tire manufacturer and safety guidelines when determining repairability.

• Designed for tread-area punctures in a range of tire sizes
• Not recommended for sidewall repairs or extreme structural damage
• Use with matching insertion tools and proper reaming equipment
• Inspect repaired tire for continued service suitability
