RMA-Approved Tire Repair Plugs

These pull-through plugs are designed for permanent puncture repairs that follow Rubber Manufacturer's Association procedures. They address injuries up to 1/4-inch (6mm) where the angle exceeds 25 degrees off perpendicular. Each plug vulcanizes chemically with cement or in a heat cure system to form a lasting seal. The box contains 50 units for professional or fleet use.

Compatibility Checks Before Ordering

These plugs form one half of a mandatory 2-piece repair and require a matching tire repair patch to meet RMA standards. They are intended solely for radial and bias-ply tubeless tires on automobiles, trucks, ATVs, and motorcycles. Verify the puncture angle and diameter fall within the stated limits before proceeding. No inner-tube or solid-tire applications are supported.

Installation Characteristics

The integrated lead wire eases insertion by guiding the stem fully into the puncture channel for a tight fit. After vulcanization, the excess stem is trimmed flush with the tread and liner surface. The process uses standard vulcanizing cement or a heat cure system without specialised equipment. No curing time or pressure specifications are provided in the data.

Questions about this item

What comes in the box and do I need to buy patches separately?

The box contains 50 pull-through plugs with integrated lead wires; STEELMAN tire repair patches must be purchased separately to complete the 2-piece RMA repair.

How do I know if the 1/4-inch plug matches the damage on my tire?

Use these plugs for puncture injuries up to 1/4-inch (6mm) that exceed 25 degrees off perpendicular on radial or bias-ply tubeless tires.

Will the plug form a permanent seal once installed in the tire?

The plug vulcanizes chemically with cement or in a heat-cure system, and the lead wire helps seat the stem fully before trimming flush with the tread.
