necessary, while component repair is in process. Metallic wipers are formed in split rings for ease in installation, and they are manufactured slightly undersize to ensure a tight fit. One side of the metallic wiper has a lip, which should face outward upon installation. Metallic wipers must be inspected for foreign matter and condition, and then installed by sliding them over the piston shaft in the proper order, as directed by the applicable MIM. The felt wiper may be a continuous felt ring or a length of felt with sufficient material to overlap its ends. The felt wiper should be soft, clean, and well saturated in hydraulic fluid during installation. Protective Closures Contamination is hazardous and expensive. To protect hydraulic systems from contaminants, use protective closures. Two types of protective metal closures are approved for sealing hydraulic equipment. They are caps and plugs conforming to appropriate military specifications. Guidelines for selection and use of protective closures for hydraulic equipment are as follows: Use caps and plugs of the proper size and material.    Never blank-off openings with wooden plugs, paper, rags, tape, or other unauthorized devices. Use closures of metal construction conforming to specifications listed in table 2-2 for sealing hydraulic system equipment, lines, tubes, accessories and components.
