1.62x2.37x0.37 inch FKM Rubber Imperial Double Lip Rotary Shaft Oil Seal with Garter Spring

Heat

1. Resistance to temperature extremes:

FKM withstands high temperature and simultaneously retains its good mechanical properties better than most other elastomers. Oil and chemical resistance also are relatively unaffected by elevated temperatures. Compounds of FKM remain usefully elastic indefinitely when exposed to laboratory air oven aging up to 204 Degrees Celsius (400 Degrees Fahrenheit) or to intermittent test exposures up to 260 Degrees Celsius (500 Degrees Fahrenheit). High temperature service limits are generally considered to be:

3 hrs. at 232 Degrees Celsius (450 Degrees Fahrenheit)
1 hr. at 260 Degrees Celsius (500 Degrees Fahrenheit)
240 hrs. at 288 Degrees Celsius (550 Degrees Fahrenheit)
48 hrs. at 316 Degrees Celsius (600 Degrees Fahrenheit)

Cold

Generally serviceable in dynamic applications down to -18 Degrees to -23 Degrees Celsius (0 Degrees to -10 Degrees Fahrenheit), although special formulations permit its use in static applications down to -54 Degrees Celsius (-65 Degrees Fahrenheit). Also, has proven to be satisfactory for static seals used under conditions approaching absolute zero.

2. Resistance to degradation by a greater variety of fluids and chemicals than any non-fluorinated elastomer, providing the best proven fluid resistance of any commercial rubber. Excellent resistance to oils, fuels, lubricants, and most mineral acids.

3. Extremely low permeability to a broad range of substances, including particularly good performance in oxygenated automotive fuels.

4. Resistance to many aliphatic and aromatic hydrocarbon fluids that act as solvents for other rubbers.

5. Exceptionally good resistance to compression set, even at temperatures which can embrittle other non-fluorinated elastomers.

6. Exceptionally good resistance to atmospheric oxidation, sun, and weather. Excellent resistance to fungus and mold.

7. Good electrical properties in low voltage, low frequency applications.

8. Low burning characteristics; inherently more resistant to burning than other non-fluorinated hydrocarbon rubbers.
