Seals It: Race-Proven Protection for Bearings and Hubs

When it comes to keeping critical drivetrain and hub assemblies clean, lubricated, and protected under punishing conditions, Seals It has earned a reputation that extends from NASCAR pit lanes to high-performance street builds. Their Bearing Protectors, Seals & Bearings lineup reflects more than 25 years of engineering sealing solutions for applications where failure simply isn't an option.

Purpose-Built for Demanding Environments

Bearing protection is about more than plugging a gap — it's about maintaining a consistent barrier against contamination, heat, and moisture while retaining the lubrication a bearing needs to survive. Seals It addresses this challenge with hub seals, axle seals, and bearing seals engineered specifically for the abuse of high-speed rotation, heavy loads, and extreme temperature cycling.

Their bearing and hub seals are designed to keep grease in and keep dirt, dust, and moisture out of the hub and bearing area — a deceptively simple function that, when executed poorly, can lead to rapid bearing wear and costly failures. In racing environments especially, contamination and heat can dramatically shorten bearing life, making a quality seal one of the most cost-effective forms of insurance available to any builder or crew chief.

What Sets Seals It Apart in This Category

Seals It approaches bearing protection with the exacting tolerances that motorsports demand. Their axle seals control fluid and prevent leaks at the point where an axle exits a housing, while their dedicated bearing seals focus on protecting the bearing itself from contamination while retaining lubrication under load. The lineup spans economy-grade axle seals for budget-conscious builds to precision sealing solutions built for NASCAR and other sanctioned racing series.

• Hub Seals — Designed to maintain a tight barrier around the hub assembly, keeping grease where it belongs and contaminants out
• Axle Seals — Available in a wide range of inner and outer diameter specifications to fit a broad variety of axle housing configurations
• Axle Seal Rebuild Kits — Comprehensive kits including replacement seal inserts and O-rings for restoring sealing performance without replacing full assemblies
• Wide 5 Hub Seals — Specialized fitment for sprint car and open-wheel racing applications that rely on Wide 5 hub configurations

Materials and Construction

Seals It products are crafted from advanced rubber and composite materials chosen for durability, heat resistance, and long-term sealing integrity. Rubber-and-steel construction appears throughout the lineup, balancing flexibility with structural rigidity — a combination that helps seals conform tightly to mating surfaces while resisting deformation under sustained mechanical stress. The brand's commitment to material quality is part of why their seals have found favor not only in motorsports, but also in agricultural, aerospace, and transportation applications.

A Trusted Name Across Industries

While Seals It built much of its reputation in competitive motorsports, their bearing protection products serve anyone who needs reliable sealing under real-world stress — from weekend racers to professional crew teams. Their seals are made in the USA and hold up to the scrutiny of environments where there is no margin for leaks, contamination, or premature bearing failure.
