Care should be taken when storing rotaryshaft lip seals to ensure optimal performance.2. Seals should be stored in a cool, dry areabelow 86 °F (30 °C) with an average relativehumidity of 40 to 70%.3. Rotating stock is important. If inventory isold, seals should be used on a “first in, first out”basis. Based on the relative low cost of a lip sealcompared to the expense associated with a failedpiece of equipment, a good practice is to discardaged inventory since old seals may havedeteriorated lip materials.4. Seals should be stored away from direct orreflected sunlight and electrical equipment toavoid UV and ozone aging of the lip material.5. Avoid storing seals in damp areas or wherehigh humidity is present. Excessive humidity willdeteriorate some seal element materials. Metalcases and springs will also rust and corrode ifexposed to high levels of moisture or humidity.6. Seals should not be exposed to radiation.7. Keep seals stored in proper packaging. Donot store unpackaged seals on the shelf.8. Do not use wire or string to tag a seal. Wirecan easily cut the seal lip. Wire or string can alsodeform the lip beyond the point of recovery andcan lead to leakage at start-up.9. Do not store seals on hooks, nails orpegboard. Over time the weight of the seal restingon the hook will deform the lip beyond recovery.10. Avoid storing seals where high levels offumes are present. Depending on the chemicaland concentration, it can chemically interact withthe lip material.03/28/062-14 Parker Hannifin CorporationEPS DivisionToll Free: (800) 233-3900www.parkerseals.com
