Frequently Asked Questions
Q: What is the Clark CL 1808141 U-Cup seal and what material is it made from?
A: The CL 1808141 is an OEM hydraulic pressure seal with a U-cup configuration, manufactured from high-strength polyurethane elastomer. The material has an estimated Shore A hardness of 90±5 and is designed for continuous industrial service in hydraulic systems.
Q: What is the maximum pressure rating of the CL 1808141 U-Cup seal?
A: The CL 1808141 is rated for system pressures up to 3,000 PSI. This pressure rating makes it suitable for standard Clark CJ55 manual pallet jack hydraulic circuits, which operate within typical industrial low-pressure parameters.
Q: Which Clark pallet jacks use the CL 1808141 U-Cup seal?
A: The CL 1808141 is designed for Clark CJ55 manual pallet jack hydraulic pump assemblies. It provides fluid retention within hydraulic cylinders and is a genuine Clark OEM part for precise compatibility.
Q: How long does the CL 1808141 seal last under typical pallet jack use?
A: The polyurethane U-cup is engineered for continuous cycling in industrial service. Lifespan depends on system cleanliness, operating temperature, and pressure duty. Seals degradation is often visible as fluid weeping from the hydraulic unit. Replace when leakage is observed to prevent system failure and load loss.
Q: What happens if the CL 1808141 U-Cup seal fails?
A: Failure of the CL 1808141 results in hydraulic fluid leakage from the pump assembly. This causes reduced lift pressure, inability to hold loads, and risk of complete hydraulic system failure. Replace immediately with an OEM CL 1808141 to restore proper sealing and system function.
