Gold and Silver I-Rotary Apex Seals

Gold Series I-Rotary Apex Seal

The Original or "Gold Series" I-Rotary Apex Seal provides the best sealing performance of any metallic apex seal regardless of the engine application, from low power normally aspirated engines to high horsepower “Drag” race engines.

The Gold Series material is manufactured and processed under a very stringent quality control process. This custom material provides the lowest level of friction and wear, excellent strength at temperature and the best performance against the rotor housing chrome surface of any metallic apex seal available on the market.

The Gold Series accuracy and precision is unmatched in the market. Key dimensional surfaces are made using an extremely accurate grinding process and every set is individually inspected, measured and matched. This allows each engine using the Gold Series I-Rotary Apex Seal to attain its maximum sealing performance.

Silver Series I-Rotary Apex Seal

The Silver Series I-Rotary Apex Seal has been developed for the perfect balance of quality, ultimate performance and cost regardless of the engine application from low power normally aspirated engines to high horsepower “Drag” race engines.

The Silver Series is made using newly developed proprietary advanced manufacturing processes that retain many of the qualities of the Gold Series I-Rotary Apex Seal at less cost.

The Silver Series material is made from the same custom base material used in the manufacture of the Gold Series, but which is processed differently to reduce cost. This material has very consistent material properties, excellent strength at temperature, a very low level of friction and wear as well as an excellent performance level against the rotor housing chrome surface.

The material qualities and consistency of the Silver Series I-Rotary Apex Seal are superior to all other available apex seals on the market except for the Gold Series I-Rotary Apex Seal.

The Silver Series accuracy and precision is unsurpassed by any other metallic apex seal except for the Gold Series I-Rotary Apex Seal.

This level of accuracy, precision and consistency is achieved through the use of proprietary processes that have allowed the larger volume manufacture of the Silver Series I-Rotary Apex Seal.
