    The outer part of an oil seal is made of metal or rubber, depending on the intended application. Metal-cased seals are a cost-effective option used when the housing bore is made of the same material, allowing for equal expansion and contraction of the materials during use. Rubber-cased oil seals provide a tight fit and are commonly used when metal-cased seals have the potential to fail. They are corrosion-resistant and capable of withstanding extreme temperatures and pressures.

    The interaction of the integrated seals with the shaft follows the dynamics of the PTFE seals. Often an additional dust seal (rubber lip or felt strip) provides an effective barrier against contaminating particles.
