Total Seal’s® 2 piece Gapless®
Piston Rings seal the end gap with the secondary rail,
virtually eliminating "Blow-By". Total Seal
pioneered this technology over 25 years ago and has
been perfecting it ever since. Available for Top and
Second Groove applications.

How it Works...
As a normal ring wears, the gap opens up, allowing
more combustion gases to escape (blow-by). The Total
Seal Gapless® ring solves the problem. Its patented
design incorporates a two-part interlocking ring that
closes off the gap and provides a better or improved
seal between the piston and cylinder.
As the Total Seal ring wears, the gap stays sealed,
even after dozens of grueling races. Blow-by is a thief.
It steals power, it shortens the lubrication life of
the crankcase oil, it causes parts to wear out prematurely,
and it continues to reduce the power as the ring gap
increases in size.
Big deal? Yes it is.
Blow-by is the escape of combustion gases past the
piston rings into the crankcase. Blow-by steals the
horsepower from your engine. It reduces usable torque.
It cuts the life of engine parts.
Racers understand what blow-by is and they know how
quickly it can render an engine uncompetitive. To keep
blow-by under control, make sure cylinder walls are
perfectly round, straight and finished to your ring
set. Use your leakdown tester to check each cylinder's
leakage after every race. Compression gauges don't test
leakdown. In fact, your weekly checklist should include
a leakdown test. If your engine is unstable, the data
you receive from checking tires or chassis setting may
And, of course, the best was to stop blow-by is to
use Total Seal Gapless piston rings in your engine.
Conventional leakdown on a very carefully prepared engine
averages 5% -8%. After a few races, with even the best
conventional high performance rings, leakdown of 12%
or more is common-and we all know that excessive leakdown
will make your engine uncompetitive and case premature
failure of your parts.
Using the Total Seal Gapless ring always keeps your
leakdown to 2% or less. Readings of 0%-1% are common
even after several races.
With Total Seal Gapless rings in your engine you get
more compression, more horsepower, more torque, cleaner
and cooler oil, better fuel economy and more stable
conditions for other testing efforts.
