5. FAQ

Q: Which type of construction equipment can use part number 707‑98‑29640 for cylinder service work?
A: Part number 707‑98‑29640 cylinder seal kit is specially developed for excavator quick coupler cylinder assembly maintenance and full overhaul service.

Q: What core sealing performance can part number 707‑98‑29640 deliver for quick coupler cylinder hydraulic circuit?
A: Part number 707‑98‑29640 cylinder seal kit maintains stable hydraulic pressure during attachment locking and releasing operations, reduces internal oil pressure loss under frequent tool‑changing load, and prevents fine metal dust and construction silt from entering cylinder interior to protect piston and rod sliding mating surfaces.

Q: What raw materials constitute this quick coupler cylinder seal kit?
A: Dynamic rod seals adopt anti‑fatigue PU polyurethane, static O‑rings are made of ozone‑resistant HNBR hydrogenated nitrile rubber, and PTFE anti‑fatigue backup ring relieves cyclic alternating pressure and avoids seal extrusion damage during repeated locking cycles.

Q: What color features do these sealing spare parts present?
A: PU sealing components are glossy jet‑black, FKM rubber fittings are dark brown‑black, PTFE pressure‑dispersion wear ring is light off‑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.
