Seal Inner Tube

The Seal Inner Tube (Winters MPN 7267) is a precision replacement axle housing seal engineered for heavy-duty drivetrain applications where fluid retention and longevity are non-negotiable. This inner seal assembly replaces worn or damaged original equipment seals in Winters differentials and axle housings, preventing gear oil leakage and contamination that can lead to premature wear and catastrophic failure. Whether you're maintaining a race car, off-road vehicle, or industrial equipment, a functioning axle seal is essential to protect expensive differential components from moisture and particle ingress.

This seal inner tube features a dual-material construction combining steel backing with molded rubber lip geometry, finished in gold paint for corrosion resistance and visual identification. The 2.280-inch outer diameter (OD) and 1.143-inch inner diameter (ID), with a wall thickness of 1.0655 inches, are precision-engineered to seat flush within Winters axle housings and maintain a positive seal across variable temperature and pressure conditions. The lip design creates a dynamic seal that actively strips oil away from rotating shafts while accommodating slight radial run-out, ensuring reliability across both street and track applications without compromising differential efficiency.

Installation of the Seal Inner Tube is straightforward during routine axle service or differential rebuild—simply remove the old seal and press the new assembly into the housing bore until it seats fully. This replacement seal is ideal for anyone performing differential maintenance, upgrading to stronger gear ratios, or rebuilding a Winters axle housing after high-performance use. Proper installation and use of quality OEM-equivalent seals like this one will extend axle housing life, maintain gear oil cleanliness, and prevent the costly repairs that result from oil starvation or contamination.
