If you push your rotary engine and with OEM apex seals, you risk damaging your engine. Stock seals, under extreme stress, have the potential to shatter into a million pieces and ruin the internal surface of your engine and its compression surface.

You’ve poured lots of time and money into your engine. Now with Power Seal Apex Seals, you can protect your investment.

Why Power Seal Apex Seals?

The Power Seal Apex Seals are unbreakable. The benefits of the Power Seal Apex Seals is that once they lose their ability to seal, your engine will lose its compression and its power. Unlike stock seals, the Power Seal Apex Seals will not shatter and destroy your engine.

Detonations happen due to bad fuel, a blocked fuel filter, a fuel pump failure, or poor tuning. If your engine suffers any damage, you can count on the Power Seal Apex Seals. They will bow or deform slightly in shape but they will not shatter into pieces and damage the housings of your engine.

These seals are designed for longevity and a lot of miles. These seals will also take on significant levels of power.
