5. FAQ

Q: What construction machinery does part number 707‑98‑22870 apply for cylinder maintenance tasks?
A: Part number 707‑98‑22870 cylinder seal kit is specially produced for mini excavator arm cylinder assembly maintenance and full overhaul service.

Q: What sealing performance can part number 707‑98‑22870 deliver for arm cylinder hydraulic system?
A: Part number 707‑98‑22870 cylinder seal kit maintains stable hydraulic pressure during arm stretching and retracting digging movements, reduces internal fluid leakage under intermittent digging load, and prevents muddy debris and fine sand from entering cylinder inner cavity to scratch piston and rod mating surfaces.

Q: What raw materials make up this arm cylinder seal kit?
A: Dynamic rod seals adopt high‑toughness PU polyurethane, static sealing O‑rings use heat‑resistant FKM fluoro‑rubber, and PTFE anti‑wear backup rings bear lateral offset force and avoid seal squeeze damage under frequent pressure fluctuation.

Q: What sealing components are contained inside this complete repair kit?
A: It includes piston seals, rod seals, buffer rings, PTFE backup rings, dust wiper seals and multi‑spec matched O‑rings for cylinder reassembly.

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.
