Total Seal T3690 30 Ductile Moly Gapless 2nd Piston Ring Kit

Total Seal Piston Rings - Ductile Moly Gapless 2nd Ring Set is engineered to provide superior cylinder sealing through Total Seal's patented Gapless® second ring technology. The innovative interlocking ring design minimizes the end-gap leakage found in conventional piston rings, helping to reduce blow-by, improve compression retention, and maintain more consistent engine performance over time. This advanced sealing technology is trusted in high-performance street and racing engines where efficiency and durability are critical.

Constructed from durable ductile iron with a moly-faced sealing surface, this ring set is designed to withstand the demands of naturally aspirated and forced-induction applications. Improved ring seal helps increase horsepower and torque potential, enhance engine vacuum, and provide better oil control while reducing crankcase contamination. Total Seal recommends Gapless® second rings for turbocharged and supercharged engines where maximizing cylinder pressure retention is essential for performance and reliability.
