5. FAQ

Q: What construction machinery does part number 707‑98‑23180 apply for cylinder overhaul jobs?
A: Part number 707‑98‑23180 cylinder seal kit is specially engineered for mini excavator boom cylinder assembly maintenance and full overhaul service.

Q: What sealing capability can part number 707‑98‑23180 deliver for boom cylinder hydraulic circuit?
A: Part number 707‑98‑23180 cylinder seal kit maintains stable hydraulic pressure during boom lifting and lowering excavation movements, reduces internal fluid bypass under variable digging load, and prevents construction dust and muddy water from invading cylinder inner cavity to protect piston and rod sliding mating surfaces.

Q: What raw materials compose this boom cylinder seal kit?
A: Dynamic rod seals adopt high‑wear‑resistant PU polyurethane, static sealing O‑rings use heat‑resistant FKM fluoro‑rubber, and PTFE low‑friction backup rings bear transverse side force and avoid seal squeeze damage under frequent pressure spikes.

Q: What color appearance do these sealing spare parts present?
A: PU sealing elements are deep jet‑black, FKM rubber fittings are dark brown‑black, PTFE low‑friction backup rings are light cream‑white.

Q: Can the sealing combination stop internal leakage and external oil seepage effectively?
A: Multi-stage sealing structure greatly reduces the risk of hydraulic oil leakage.

Q: Can this product prevent hydraulic oil leakage effectively?
A: The precise size design effectively reduces internal leakage and external oil seepage.

Q: What construction scenarios often require this arm cylinder seal kit for regular maintenance?
A: It is widely used for maintaining mini excavators working on villa foundation projects, landscape engineering, pipeline trenching and rural road reconstruction.
