5. FAQ

Q: What kind of hydraulic pressure can these sealing components withstand steadily?
A: It can adapt to frequent pressure changes under normal construction working conditions.

Q: What kinds of materials are contained within this cylinder seal kit?
A: It combines TPU, NBR, FKM and reinforced PTFE composite materials. Different components adopt corresponding materials to resist high‑pressure hydraulic oil and abrasive construction‑site dust.

Q: What colors can I find among these sealing components?
A: The rod seals and O‑rings are mostly black, buffer rings show light beige tone, and anti‑extrusion backup rings present off‑white color.

Q: Which cylinder does this whole repair kit serve on the machine?
A: It is specially made for arm hydraulic cylinder, taking charge of sealing piston and rod position to prevent internal leakage and external oil seepage.

Q: Can this set handle frequent arm lifting and digging cycles under heavy load?
A: Yes, it can stand repeated pressure surges, reciprocating friction and impact load during rock excavation and material handling work.

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.
