5. FAQ
Q: What construction machinery does part number 707‑98‑23870 fit for cylinder maintenance work?
A: Part number 707‑98‑23870 cylinder seal kit is specially developed for mini excavator arm cylinder assembly maintenance and full overhaul service.
Q: What sealing performance can part number 707‑98‑23870 realize for arm cylinder hydraulic circuit?
A: Part number 707‑98‑23870 cylinder seal kit maintains stable hydraulic pressure during arm extending and retracting excavation movements, reduces internal flow loss under short‑stroke digging load, and prevents site mud and fine gravel from invading cylinder inner cavity to protect piston and rod matching surfaces.
Q: What raw materials compose this arm cylinder seal kit?
A: Dynamic rod seals adopt high‑pressure resistant PU polyurethane, static O‑rings use aging‑resistant HNBR hydrogenated nitrile rubber, and PTFE high‑pressure backup rings bear transverse heavy force and prevent seal squeeze damage under frequent pressure peaks.
Q: What color appearance do these sealing spare parts display?
A: PU sealing components are matte jet‑black, NBR rubber parts are glossy deep black, PTFE anti‑friction backup rings are light cream‑white.
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.
