TECH Tire Repairs Permacure II Tubeless Tire Plug Inserts 3-3/4 in — Box of 50, Nylon-Reinforced Vulcanizing Bond

TECH Tire Permacure II 3-3/4-inch inserts are reinforced tubeless plug repairs that chemically bond to a tire for durable emergency fixes.

When you need a dependable tubeless plug that holds up better than sticky string plugs, these Permacure II inserts deliver a reinforced, vulcanizing solution designed for quick roadside repairs and long-lasting adhesion. Sold in a box of 50, each 3-3/4" insert works with TECH Flow-Seal Vulcanizing Fluid for the strongest chemical bond, making the kit a practical choice for drivers, mechanics, and fleet operators who want a professional-grade temporary repair option.

How do these inserts stay in place compared with ordinary string plugs?

Permacure II inserts are engineered to resist drying out and falling out like conventional sticky plugs. The nylon-reinforced construction plus the ability to use a vulcanizing fluid creates a chemical bond with the tire rubber rather than relying solely on adhesion.

• Nylon reinforcement for structural stability under load
• Compatible with TECH Flow-Seal Vulcanizing Fluid for chemical bonding
• Seals out moisture and road contaminants to reduce failure risk

Can I use these inserts for highway driving or only as temporary fixes?

These inserts provide a robust temporary repair that will get you safely to a service location, but they are considered a temporary solution for high-speed, long-distance driving. For sustained highway use, a professional plug-and-patch or tire replacement is recommended after using a Permacure II insert.

• Ideal for emergency roadside repairs and local driving
• Recommended follow-up with a shop for long-term highway reliability
• Works best when installed correctly and paired with vulcanizing fluid

What kinds of tires are compatible with TECH Permacure II inserts?

These 3-3/4" inserts are versatile and suitable for a range of tubeless tires including passenger car tires, small truck tires, lawn mower tires, and many UTV tires. Their reinforced design adapts to various puncture scenarios where a tubeless plug repair is appropriate.

• Passenger cars and light trucks
• ATVs, UTVs, and small off-road vehicles
• Lawn and garden equipment tires with tubeless construction

How do I get the best results when installing a Permacure II insert?

Preparation and the right materials make a big difference: clean the puncture, use a proper insertion tool, and apply TECH Flow-Seal Vulcanizing Fluid for a chemical bond. Proper seating and trimming of the insert ensure a secure seal and reduce the chance of leakage or dislodgement.

• Ream and clean the puncture channel before inserting
• Apply TECH Flow-Seal Vulcanizing Fluid to the insert and hole
• Seat the plug fully, trim excess, and check for air loss after inflation
