Seals

Discover® Wheel Seals

Discover® Seals feature a high-grade temperature-resistant HNBR-PTFE material and multi-labyrinth sealing features for long-life applications. Discover seals are designed for today’s increased highway speeds, and higher temperature air disc brake applications.

Features

Discover seals’ bonded rubber outer diameter offers easy installation with piloted entry for a precise installation every time. The ridged double wall steel case is the impact point for the tool head, protecting the seals’ internal geometries. The correct STEMCO installation tool never touches the mechanical portion of the seal, eliminating installation failures.

The Discover seals’ patented “SMART” anti-rotation features on the ID ensure positive positioning and locking of the seal to the spindle shoulder, while still allowing easy removal for replacement.

The premium HNBR-PTFE sealing element is well suited for today’s new equipment with air disc brakes designed to meet the reduced stopping distance requirements. The premium sealing element is protected by a four-zone labyrinth that provides unmatched contaminant exclusion and performance.
