Frequently Asked Questions
Q: What is the maximum pressure rating for the CL 1808144 O-ring?
A: The CL 1808144 is rated for hydraulic pressures up to 2500 PSI. This rating applies to hydraulic pump assemblies in Clark CJ55 manual pallet jacks under standard operational conditions.
Q: What material is the CL 1808144 O-ring made from and what is its Shore A hardness?
A: The CL 1808144 is manufactured from nitrile rubber with a Shore A hardness of 70, conforming to ASTM D2000 material specifications. Nitrile provides broad chemical compatibility with standard hydraulic fluids and good temperature stability.
Q: What is the AS568A specification and does the CL 1808144 conform to it?
A: AS568A is the standard O-ring sizing specification used across the hydraulics industry. The CL 1808144 is manufactured to full AS568A compliance, ensuring dimensional accuracy and compatibility with standard O-ring grooves in Clark pump assemblies.
Q: How often should the CL 1808144 O-ring be replaced?
A: The CL 1808144 does not have a set replacement interval. Replace it when hydraulic leakage develops at the seal, or during routine pump rebuild. O-rings degrade over time due to heat and pressure cycling, so replacement during preventive maintenance extends equipment life.
Q: Is the CL 1808144 compatible with other Clark pallet jack models besides the CJ55?
A: The CL 1808144 is engineered for the Clark CJ55 manual pallet jack. Do not assume compatibility with other Clark models without verifying part numbers. Using incorrect O-rings can cause leaks and system failure.
