QUAD RING
Frequently Asked Questions
Q: What is a quad ring and how does the CL 25K040112 differ from a standard O-ring?
A: A quad ring (also called a quad seal or X-ring) has four sealing edges instead of the two found on a standard O-ring. The CL 25K040112 quad ring is designed for Clark electric lift truck hydraulic sealing applications where enhanced sealing and lower friction are needed compared to conventional O-rings.
Q: Where is the CL 25K040112 quad ring installed on Clark lift trucks?
A: The CL 25K040112 is used for pressure sealing in Clark hydraulic systems on electric lift trucks and pallet jacks. The specific location depends on your equipment model. Consult your parts diagram or maintenance manual to identify the exact component location and fitment.
Q: What are the advantages of the quad ring design in hydraulic systems?
A: Quad rings like the CL 25K040112 provide superior sealing with four contact points, reduce friction in dynamic applications, and lower operating temperatures compared to O-rings. This design extends component life and improves system efficiency in Clark hydraulic equipment.
Q: Can the CL 25K040112 quad ring be substituted for a standard O-ring?
A: Do not substitute a quad ring for an O-ring or vice versa without verifying OEM specifications. The CL 25K040112 must be used in applications designed for quad rings. Using the wrong seal type can result in leaks or seal failure. Always reference your equipment manual for the correct part.
Q: What is the replacement interval for the CL 25K040112?
A: Replace the CL 25K040112 when hydraulic leaks develop, during system maintenance, or if the seal shows visible damage. Quad rings generally last 2 to 4 years under normal operating conditions. High-pressure or continuous-use applications may require more frequent replacement.
