Viton Hub Seal Wide 5

The Winters Viton Hub Seal Wide 5 (part number 7210V) is an inner wheel hub seal engineered for high-performance wide 5 bolt-pattern wheels commonly found in off-road, racing, and specialty vehicle applications. This seal features a 3.486-inch outer diameter and 2.379-inch inner diameter with a 0.455-inch thickness, combining steel construction with Viton elastomer for superior chemical and temperature resistance in demanding field conditions.

The Viton compound is critical for users operating in harsh environments—salt spray, extreme heat cycles, and exposure to fuels or solvents that would degrade standard rubber seals. Winters is a recognized supplier of precision hub and bearing components for the motorsports and off-road segments, where seal integrity directly impacts wheel bearing longevity and vehicle reliability. The single-lip design reduces friction compared to dual-lip seals while maintaining effective debris exclusion, making this seal ideal for lower-speed tactical recovery operations and patrol vehicle maintenance.

This replacement seal suits operators managing wide 5 hubs on custom or vintage platforms—including certain military surplus and law enforcement fleet vehicles—where OEM seal sourcing is difficult. The lightweight design (0.17 lbs) and compact envelope allow straightforward installation without requiring hub disassembly. Proper seal replacement extends wheel bearing service life and reduces the risk of lubricant loss during extended patrol or training operations.

Sold as an individual seal unit, this component is essential for field teams maintaining wide 5 equipped vehicles where bearing integrity cannot be compromised. The Viton elastomer compound ensures performance across the temperature and chemical exposure ranges encountered in real-world operational settings.
