5. FAQ

Q: What engineering machinery does part number 707‑98‑12380 support for overhaul and maintenance jobs?
A: Part number 707‑98‑12380 cylinder seal kit is designed for wheel loader boom cylinder assembly maintenance and full overhaul work.

Q: What key sealing performance can part number 707‑98‑12380 deliver for boom cylinder hydraulic circuit?
A: Part number 707‑98‑12380 cylinder seal kit stabilizes hydraulic pressure during boom lifting and descending cycles, minimizes internal fluid bypass under heavy material load, and keeps construction sand and debris out of cylinder inner cavity to protect internal precision parts.

Q: What main raw materials are used for this boom cylinder seal kit?
A: Dynamic rod seals are made of high‑toughness PU polyurethane, static sealing O‑rings adopt heat‑resistant FKM fluoro‑rubber, and PTFE high‑load anti‑extrusion backup rings absorb side thrust and prevent seal squeezing damage under peak pressure.

Q: What color appearance will customers see for these sealing components?
A: PU sealing elements are deep jet‑black, FKM rubber parts are dark brown‑black, PTFE high‑load anti‑extrusion backup rings are light creamy‑white.

Q: What sealing accessories are packed inside this whole repair kit?
A: It includes piston seals, rod seals, buffer rings, PTFE backup rings, dust wiper seals and multiple specifications of matching O‑rings for cylinder reassembly.

Q: Where is this cylinder seal kit assembled on articulated dump truck?
A: These sealing components are fitted inside cylinder barrel and cylinder head, surrounding piston and reciprocating hoist cylinder rod.

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.
