ZERINT TP-M13W Tyre Repair Patch & Plug Kit — 24‑Piece Wrapped‑Stem Plugs (3 Sizes) for Chemical or Heat Vulcanization

ZERINT TP-M13W is a 24-piece combination tire repair kit with three wrapped-stem plug-and-patch sizes designed for chemical or heat vulcanization in radial and bias-ply tires.

This compact kit supplies professional-quality wrapped-stem plug-and-patch assemblies in three lengths to address a wide range of puncture sizes. Each unit combines a vulcanizing gum stem with an attached patch featuring blue poly backing to promote bonding during chemical or heat vulcanization. The kit delivers repeatable, service-bay grade repairs for passenger and light-truck tires when installed per accepted vulcanization procedures.

What sizes are included and when should I use each?

The TP-M13W contains 24 pieces total — eight of each size — so you have options for small to larger punctures. Choose the shortest stem for narrow punctures and the longer stems for deeper or larger holes that need more filler and surface contact.

• 1/6" wrapped stem with 1 3/8" patch (35 x 4 mm) — for small punctures and shallow repairs.
• 1/4" wrapped stem with 1 3/4" patch (45 x 6 mm) — for medium punctures and standard service calls.
• 3/8" wrapped stem with 2 3/8" patch (60 x 9 mm) — for larger punctures or irregular holes needing extra sealing.

How does the wrapped stem and patch design work?

Each assembly pairs a wrapped stem filled with premium vulcanizing gum to fill the puncture and an overlying patch that bonds to the inner liner. The gray vulcanizing gum and blue poly backing are formulated to assist chemical or heat-activated vulcanization, providing a secure repair when installed correctly.

• Wrapped stem delivers internal fill and conforming shape inside the puncture channel.
• Attached patch offers a bonded sealing surface across the inner tire liner.
• Gray vulcanizing compound and blue poly backing improve adhesion during vulcanization.

Which tire types and repair methods is this kit compatible with?

ZERINT TP-M13W is made for use in both radial and bias-ply tires and is intended for repairs performed via accepted chemical or heat vulcanization processes. It’s not a quickplug for temporary roadside fixes; the kit is built for permanent, service-shop style repairs.

• Suitable for passenger and light-truck radial and bias-ply tires.
• Designed for chemical (cold) vulcanization or traditional heat vulcanization methods.
• Requires proper cleaning, reaming, and vulcanizing equipment for durable results.

What should I expect during installation and performance?

When installed following standard vulcanization procedure, the wrapped stem fills the puncture channel while the patch bonds to the carcass, producing a sealed repair area. Correct application and curing time determine the repair’s longevity; this kit’s materials are selected to support consistent bonding and service life comparable to common shop repairs.

• Prepping the hole and using the right vulcanizing agent are essential for a secure bond.
• Heat or chemical cure time and pressure affect final repair strength and sealing.
• Post-repair inspection and leak testing confirm a successful repair before returning the tire to service.

Who is this for: The ZERINT TP-M13W kit is intended for tire technicians, service centers, fleet maintenance shops, and experienced DIYers who perform proper vulcanized repairs. It’s ideal for those who need multiple sizes on hand for passenger and light-truck tire punctures and who use accepted chemical or heat vulcanization methods rather than temporary plugs.
