A method of installing a mechanical seal includes wrapping a sleeve around a shaft, placing the seal over the wrapped sleeve and shaft, sliding the seal along the wrapped sleeve and shaft, toward a housing, and pressing the seal into seat in the housing. The sleeve has dimensions of length at least about same as length of the shaft protruding from the housing and width at least greater than the circumference of the shaft. Thickness of the sleeve ranges from about 0.01 inches (0.254 mm) to about 0.05 inches (1.27 mm). The sleeve is formed of polyethylene terephthalate, low-density polyethylene, polyvinyl chloride, high-density polyethylene, other elastomer, other polymer, or combinations of these. The sleeve may include a lubricant. |
