4. FAQ
Q: What four distinct raw materials compose all sealing accessories inside this maintenance kit?
A: The complete repair assortment consists of high compression-resistant solid cast PU, mica mineral flake filled modified PTFE, high heat & chemical resistant FKM fluoroelastomer and sisal woven base phenolic resin saturated anti-abrasion piston guide fabric.

Q: What natural original color does each sealing part present without artificial pigment or surface coating treatment?
A: Solid cast PU main dynamic seals are soft off-white with fine smooth texture, mica-filled PTFE backup rings are silvery grey with subtle flake grain, FKM rubber static fittings are deep coffee brown, sisal phenolic fabric wear rings are earthy orange brown.
Q: What core sealing function does solid cast PU realize inside large loader’s dipper arm hydraulic cylinder?
A: As the core reciprocating sealing component, solid cast PU utilizes outstanding elastic recovery performance to lock high-pressure hydraulic fluid inside cylinder chamber and prevent oil leakage while dipper arm stretches and retracts repeatedly to shovel oversized rocks and dense piled aggregate under heavy instantaneous payload pressure.
Q: What is the core design intention of matching mica-filled PTFE as auxiliary backup ring cooperating with primary PU seal?
A: It fills tiny interstitial gaps inside piston mounting grooves and protects PU sealing lip from extrusion tearing caused by abrupt hydraulic pressure spikes when bucket crashes onto rigid bedrock during high-intensity quarry loading operations.
Q: What unique performance advantages make FKM fluororubber superior compared with conventional regular NBR rubber?
A: FKM features excellent long-term thermal oxidation resistance and anti-fuel swelling property, keeping stable sealing tightness after long-time soaking in high-temperature aged contaminated hydraulic oil under nonstop full-load round-the-clock quarry operation.
