Radiator Specialty Co. said its new Extreme Puncture Seal aerosol tire inflator and sealer is freeze-resistant down to –400 and heat-resistant inside tires to well above 1200. The product, which is TPMS safe, is available in a 16-ounce size for automobile tires and a 14-ounce size for off-road, lawn and garden equipment, and all-terrain vehicles. Both aerosol cans include a convenient 6-inch hose for easy application through the tire valve. The applicator hose is stored in the lid until needed, the company said.
