Exhaust system seals designed for extreme temperatures, ideal for applications in four-stroke engines. The material includes double-sided Viton® elastomer coating on stainless steel, ensuring precise sealing at high temperatures and under harsh conditions. The seals feature an outer steel layer that supports the inner Armor-400 layer, which is heat resistant up to 1,800ºF, guaranteeing maximum resistance against blowout or displacement caused by over-tightening. Made in the USA.
