Description

Real-Seal header gaskets from Flowtech are a revolutionary breakthrough in sealing technology. Constructed of separate layers of "dead soft" aluminum, they provide a do-it-once solution that won't burn or blow out. These water and weather-resistant gaskets conform to create a leakproof seal, are suitable for port matching, and you can use them over and over again.
