5. FAQ

Q: What heavy‑duty construction equipment does part number 707‑98‑25970 match for cylinder overhaul jobs?
A: Part number 707‑98‑25970 cylinder seal kit is specially developed for wheel loader lift cylinder assembly maintenance and complete overhaul service.

Q: What sealing performance can part number 707‑98‑25970 realize for lift cylinder hydraulic circuit?
A: Part number 707‑98‑25970 cylinder seal kit maintains stable hydraulic pressure during boom lifting and lowering for material loading tasks, reduces internal oil leakage under heavy bucket load, and blocks quarry dust and muddy mixture from entering cylinder chamber to protect piston and rod mating surfaces.

Q: What raw materials compose this lift cylinder seal kit?
A: Dynamic rod seals adopt high‑wear‑resistant PU polyurethane, static sealing O‑rings use ozone‑resistant HNBR hydrogenated nitrile rubber, and PTFE impact‑resistant backup ring absorbs sudden shock force and prevents seal extrusion damage under frequent pressure surges.

Q: What color appearance do these sealing spare parts feature?
A: PU sealing elements are deep dark‑black, HNBR rubber fittings are glossy jet‑black, PTFE pressure‑resistant backup rings are light ivory‑white.

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.
