Frequently Asked Questions
Q: What is O-ring CT 021104 used for in material handling equipment?
A: O-ring CT 021104 is a hydraulic or pneumatic seal used in Caterpillar electric lift truck systems. It seals cylinder ports, pump connections, and valve assemblies to prevent fluid or air leakage.
Q: Is CT 021104 compatible with Caterpillar PMX 45 pallet jacks?

Q: Can I use a different O-ring size as a substitute for CT 021104?
A: No. O-ring seals must match exact diameter and cross-section specifications. Using an incorrectly sized O-ring will result in leakage and potential system failure. Always use the correct part number.
Q: When should O-ring CT 021104 be replaced?
A: Replace CT 021104 if you observe fluid or air leakage at the seal location, visible cracking or hardening of the elastomer, or loss of system pressure. O-rings typically require replacement during major system service.
