National Oil Seals has launched an application-specific hand-install Red 375 Series seal with Dynamic Edge technology for commercial vehicles.
Designed to simplify installation, National’s hand installable seals offer tool-free, on-the-fly installation that eliminates the need to find the correct installation tool and saves potential damage to the seal through incorrect installation, the company says.
Originally introduced in 2011, National says its Dynamic Edge technology brought a new level of protection to commercial vehicle wheel-end applications through its ability to deflect contaminants from the wheel end components, eliminating leading causes of premature seal and bearing failure.
Its labyrinth design slows contamination into the seal via the creation of a longer pathway that makes it more difficult for dirt and other impurities to infiltrate the seal. Unique design features make for easy installation and rib technology maintains positive bore retention, assuring the seal stays in place during the service life, the company says.
“For over 75 years, the National brand has developed a reputation for engineering quality and developing dependable products for virtually any type of wheel-end repair,” says Greg Upton, national product manager. “The National hand-install seal is another innovation that will help fleets and operators minimize their downtime through ease of installation, in addition to preventing early seal failure due to contamination.”
