5. FAQ
Q: What is the main working principle and sealing function of thermoset PU in the boom cylinder?
A: As the core dynamic sealing component, thermoset PU features excellent compression recovery and wear resistance. It tightly fits the reciprocating piston rod and inner groove, effectively blocking high-pressure hydraulic fluid leakage when the boom lifts up and lowers down frequently under heavy load during excavation and material handling operations.


Q: Why is pyrophyllite-filled PTFE adopted as the matching back-up ring for PU main seals?
A: This modified PTFE material can fill tiny assembly gaps inside piston grooves. When the excavator boom bears sudden impact load and causes instant hydraulic pressure surge, it can effectively buffer pressure and prevent the edge of PU seals from being squeezed, deformed or torn, greatly extending the overall service life of the sealing system.

Q: What unique performance advantages does FKM rubber have compared with ordinary rubber materials?
A: FKM boasts outstanding resistance to high temperature, oil aging and chemical corrosion. It can keep stable sealing performance for a long time even when contacting overheated and oxidized hydraulic oil inside the closed cylinder, which makes it perfectly suitable for high-heat static connection positions that work continuously for hours.

Q: Where are FKM rubber seals mainly installed on the boom cylinder?
A: FKM rubber pieces are primarily used for static sealing on cylinder end covers, flange joints and high-pressure pipeline threaded ports. These positions are close to the engine heat source and bear long-term oil immersion, so FKM’s high temperature and oil resistance can fully play its role here.
