High dielectric strength, high-temperature silicone tape wraps around ignition wire, boots and connectors to provide added insulation Extra insulation keeps spark energy contained within the wire, preventing high-voltage leaks and resulting misfire Also seals out moisture, while protecting the wire from the harmful effects of oil and excessive heat Specially formulated silicone rubber vulcanizes automatically, providing adhesion when tape surfaces make contact An excellent alternative to applying shrink sleeves and insulated wire sleeving One-inch wide tape packaged in 12-foot rolls
