Description
CAT 421-4024 is identified in the supplied CAT stock list as SEAL U CUP. U-cup seals use a pressure-responsive lip profile to retain hydraulic fluid around reciprocating rods or pistons. Seal diameter, profile, material, pressure capability and installation orientation depend on the original CAT cylinder or hydraulic arrangement. Correct surface condition and installation direction are essential for service life. Verify rod or piston diameter, groove dimensions, operating pressure, equipment serial number and CAT SIS before installation.
