Gapless Rings

GO GAPLESS®

Total Seal® pioneered Gapless® technology over 50 years ago. Our Gapless® piston ring design provides consistent performance that doesn’t fade with opening end gaps. They are used for all aspects of Motorsports, Diesel, Industrial, Compressors and Aviation.

KEY FEATURES:

Total Seal® Gapless® patented Top or 2nd Piston Rings provide:

  • Elimination of blow
  • Increased horsepower & torque
  • Longer engine life
  • Better sealing
  • Saves money (fewer tear-downs)
  • Cleaner, cooler engine oil
  • Better oil control
  • Increased intake signal
  • Wider torque curve
  • More engine vacuum

Why Choose a Gapless® Top or Gapless® 2nd Ring?

A Gapless® top provides the greatest performance benefit (increased horsepower and crankcase vacuum). However, a Gapless® 2nd provides excellent oil control and blow-by prevention (less oil consumption). As such, we typically recommend a Gapless® top for naturally aspirated applications, especially V8 and straight engines. For flat (horizontally opposed) engines and turbo or super-charged engines, we recommend a Gapless® 2nd. Most Total Seal® piston ring styles are available in Gapless® configurations.
