Frequently Asked Questions
Q: What equipment does the HY 61142 O ring fit?
A: The HY 61142 is an O ring seal used in hydraulic cylinders and pump assemblies on Hyster electric lift trucks. This part is commonly found in the mast tilt circuit and load-handling hydraulic systems. Confirm your equipment model and component cavity specifications before ordering.
Q: What are the specifications and material of the HY 61142?
A: O ring seals are typically manufactured from nitrile (NBR) elastomer in standard sizes. The HY 61142 is designed for medium-pressure hydraulic applications in industrial lift truck environments. Material composition and dimensions are specified by the original equipment manufacturer to ensure compatibility with specific fluid types and operating temperatures.
Q: Can I use the HY 61142 in cold storage or high-temperature environments?
A: Standard nitrile O rings have temperature operating ranges typically between minus 40°F and 212°F. If your equipment operates in cold storage (below minus 20°F) or elevated temperatures, verify material compatibility. Contact us if you require EPDM or specialized elastomer alternatives for extreme environments.
Q: What is the lifespan of the HY 61142 O ring?
A: O ring lifespan depends on duty cycle, fluid condition, and operating pressure. Typical replacement intervals range from 2 to 5 years in regular industrial use. Replace if leakage occurs, rubber shows visible cracking or hardening, or preventive maintenance schedules indicate seal replacement.
