– Polyurethane seals improve resistance to oil and chemicals, increasing service life and decreasing down time.
– Will not crack, dry out or tear like the conventional rubber seals.
– Rated to -40° F.
– Automatically adds air to, or exhausts air from air suspension to maintain constant static design height.
– Does not respond to short duration dynamic changes in axle position, thus reducing air consumption which extends compressor life and saves fuel.
