Aluminum Seal Steel Tube

The Winters Aluminum Seal Steel Tube (Part No. 2841) is a precision axle housing seal engineered for high-performance drivetrain applications requiring reliable inner sealing at the axle tube interface. This component features a red anodized aluminum body paired with a critical steel axle tube seal, designed to contain differential fluid and prevent contamination ingress in demanding operating conditions.

The seal assembly incorporates an O-ring design with a 2.625-inch outer diameter and a 2.605-inch inner diameter, matched to a 2.600-inch ID steel axle tube specification. This precision tolerance stack ensures a controlled interference fit that maintains sealing integrity under axle load and rotational speeds typical of automotive and light-duty off-road applications. The red anodized finish on the aluminum housing provides corrosion resistance and visual identification on assembly lines and during maintenance procedures.

This seal is specified for axle assemblies where inner seal replacement is required during differential service, bearing replacement, or when original seals show signs of weeping or fluid loss. Technicians performing axle work, restorations, or custom drivetrain builds rely on Winters components to restore OEM sealing performance. Weighing only 0.42 pounds, the compact design simplifies installation in tight axle housing configurations without requiring modification to surrounding components.

Winters is recognized in the automotive restoration and performance market for manufacturing precision seals and bearing components to exacting specifications. This particular seal assembly addresses the inner axle tube interface—a critical point where contamination can compromise differential longevity if inadequately sealed. Each unit ships as a single complete seal assembly, ready for installation without secondary sorting or inspection.
