4. FAQ

Q: What core material characteristics does piston seal ring part number 547-6515 exhibit?
A: Part number 547-6515 adopts polyurethane blended with PTFE filler. This material formula delivers outstanding wear‑resistant property and low‑friction performance, keeping stable sealing pressure under frequent hydraulic cylinder reciprocating movement and heavy‑load impact.

Q: What surface and appearance features can buyers observe for piston seal ring part number 547-6515?
A: For part number 547-6515, the main sealing body shows opaque dark‑blue surface, and the auxiliary anti‑extrusion backup ring presents milky‑white tone, without extra surface painting or adhesive coating treatment.

Q: Where is this piston seal ring installed on track excavator?
A: This seal ring fits into the piston groove inside hydraulic cylinder, located between piston outer diameter and cylinder tube inner wall.

Q: What key working functions does this piston seal ring provide?
A: It separates two hydraulic oil chambers inside cylinder, blocks internal hydraulic‑oil leakage, and maintains stable working pressure for boom, arm and bucket cylinder assemblies.

Q: Can this ring work independently without matching main piston sealing elements?
A: It acts as guiding and auxiliary sealing part; dedicated main piston seals are still required for full pressure holding.olding effect.

Q: What storage suggestions do you offer for these PTFE sealing accessories?
A: Keep goods in cool, dry warehouse. Avoid persistent high temperature and long-time ultraviolet radiation to slow material aging.

Q: What engineering projects commonly require replacement of this piston seal ring?
A: It serves routine maintenance of hydraulic cylinder piston sealing assemblies on medium crawler excavators, widely used in urban infrastructure, highway subgrade construction, small quarry loading and residential foundation excavation projects.
