ZERINT TP-M13W Combination Repair Unit Kit

ZERINT TP-M13W is a combination tire repair kit containing three wrapped-stem plug sizes with matching patches, built for chemical or heat vulcanization in radial and bias-ply tires.

This repair unit kit supplies professional-grade wrapped stems and matching repair patches in three common sizes so you can match the plug to the puncture. Each stem is coated with premium vulcanizing gum and the patches feature gray vulcanizing rubber with a blue poly backing for reliable adhesion during vulcanization. The kit is intended for use where a bonded, vulcanized repair is required rather than a simple sealant or mushroom plug.

How do the different sizes cover common punctures?

The kit includes three length-and-width combinations so you can choose a stem-and-patch assembly that suits small to larger punctures. Shorter stems with smaller patches work for nail-sized holes, while the larger stem-and-patch pairs address bigger punctures and gashes in the tire carcass.

• Wrapped stem 1/6" with patch 1 3/8" (35 x 4 mm) — 8 pieces for small punctures.
• Wrapped stem 1/4" with patch 1 3/4" (45 x 6 mm) — 8 pieces for medium punctures.
• Wrapped stem 3/8" with patch 2 3/8" (60 x 9 mm) — 8 pieces for larger punctures.

What materials and design features ensure a durable repair?

Each stem has a wrapped core covered in premium vulcanizing gum that bonds to the tire during heat or chemical vulcanization. Patches are made with gray vulcanizing rubber and a blue poly backing to promote consistent adhesion and a clean finish during the curing process.

• Wrapped stems for secure mechanical and chemical bond.
• Gray vulcanizing gum in stem and patch for uniform compatibility.
• Blue poly backing on patches for alignment and handling during installation.
• Compatible with both heat and chemical vulcanization methods.

Can this kit be used on all tire constructions and repair methods?

The TP-M13W kit is specified for use on radial and bias-ply tires and is designed for repairs that require vulcanization rather than temporary sealing. It performs best when installed by a trained technician using approved vulcanizing procedures and equipment.

• Suitable for radial and bias-ply tire repairs.
• Intended for chemical or heat vulcanization processes.
• Not a one-step inflation sealant; requires proper vulcanization steps.
• Works with standard shop repair tools and curing equipment.

Who is this for: The ZERINT TP-M13W combination repair kit is aimed at tire service shops, mobile repair technicians, and experienced DIYers who perform bonded tire repairs. If you need a selection of wrapped stems and matching patches that are compatible with heat or chemical vulcanization and suitable for both radial and bias-ply tires, this kit supplies three common sizes with eight pieces each to handle a range of punctures and cuts.
