Frequently Asked Questions
Q: What equipment does the WM 35P1189 o ring fit?
A: The WM 35P1189 o ring is compatible with multiple electric lift truck models from Crown, Toyota, Raymond, and Yale. Verify your equipment model and hydraulic system specifications before ordering to ensure proper fitment.
Q: What are the specifications for the WM 35P1189?
A: The WM 35P1189 is a standard metric o ring designed for hydraulic seal applications on electric lift equipment. Confirm your equipment documentation for exact inner diameter, cross-section, and material grade requirements.
Q: How long does the WM 35P1189 o ring last before replacement?
A: O ring lifespan depends on pressure cycles, temperature exposure, and hydraulic fluid type. Most hydraulic seals require replacement every 2 to 5 years or when equipment shows leaking at hydraulic connection points. Check your equipment maintenance schedule for specific intervals.
Q: What causes the WM 35P1189 o ring to fail?
A: Common failure causes include pressure spikes exceeding rated limits, incompatible hydraulic fluid, temperature extremes, age-related material hardening, and improper installation during reassembly. Slow leaks at connection points are the first sign of wear.
Q: What material is the WM 35P1189 o ring made from?
A: The WM 35P1189 is constructed from nitrile (NBR) elastomer, which provides reliable sealing in standard hydraulic applications with good resistance to mineral-based hydraulic fluids and moderate temperature ranges.
