  • The Discover XR seal’s exclusive GlideLock technology reduces installation force by 50%, simplifying the installation process and reducing heat generation.
  • It also offers easy removal while also exhibiting strong locking for additional security.

LONGVIEW, TX (January 25, 2022) – STEMCO, an Enpro company (NYSE: NPO) and manufacturer of heavy-duty components and solutions for commercial vehicles, has announced the launch of the new Discover XR wheel seal. This advanced wheel seal solution was previously only available as a part of the Trifecta pre-adjusted hub assembly, but is now available as a standalone product.

The Discover XR seal features exclusive GlideLock technology that eliminates installation issues by reducing installation force by 50% with no prelube required. This helps address key concerns surrounding seal failure, including cocked seals and excessive heat generation.

The seal also offers easy removal without tools while exhibiting strong locking with its patented “SMART” anti-rotation features. It is also protected by a four-zone labyrinth that provides excellent contamination exclusion, reducing wear and extending the life of the seal.

“At STEMCO, we pride ourselves as being the ultimate industry partner when it comes to wheel ends, and this Discover XR seal continues that vision,” said Chip Stuhr, Vice President and General Manager of STEMCO. “It meets the demands and challenges of the commercial trucking industry, extending the life of vehicles and components, and ultimately making the roadways safer.”

Prospective customers are encouraged to install the Discover XR seal with STEMCO’s other premium
wheel end components to take advantage of a special warranty through the Platinum Performance System™. This system combines the Discover XR or Guardian® HP seal, the Pro-Torq® or Zip-Torq® nut, and the Sentinel® hub cap for a three-year warranty.
