12B0491 o-ring Liugong CLGB320C bulldozer spare parts

Short Description:

12B0491 O‑ring is special rubber seal for hydraulic system and transmission mechanism of Liugong CLGB320C bulldozer. It fills fitting clearance by rubber elasticity to prevent outward leakage of hydraulic oil and gear oil, and block mine sediment and sewage from invading sealing grooves so as to protect precision mating pairs such as spools and bearings. Timely replacement is required when O‑ring is hardened, cracked, swollen or extruded damaged to avoid system pressure relief and oil‑leakage failure.

advantages

Oil‑resistant rubber material, resistant to immersion of hydraulic oil and gear oil, anti‑aging and adapt to temperature fluctuation of bulldozer working environment
Cross‑section dimension strictly complies with OEM standard with reasonable pre‑compression, delivering good sealing performance for both static and dynamic sealing
Certain extrusion‑resistance and wear‑resistance, withstand hydraulic‑system pressure shock and adapt to mine vibration working environment
Stable dimensional accuracy, directly fit into corresponding sealing groove without on‑site cutting or grinding.

FAQ

Q: Can visually intact O‑ring be reused after disassembly?
A: Invisible permanent compression deformation occurs after disassembly. Reuse is strictly forbidden under mine heavy‑load condition, new part is recommended.
Q: Can over‑size O‑ring make up for slightly worn groove?
A: Not allowed. Non‑standard O‑ring is easy to be sheared under pressure. Repair groove first and adopt standard spare parts.
