4. FAQ

Q: What four kinds of raw materials constitute all sealing components inside this maintenance repair kit?
A: The whole repair pack is composed of high tear-resistant extruded PU, talcum mineral powder compound modified PTFE, outdoor weather & ozone resistant EPDM elastomer and coconut coir woven base phenolic resin impregnated anti-wear piston guide fabric.

Q: What original natural color does each sealing part keep without artificial pigment blending or surface paint coating?
A: Extruded PU main dynamic seals are pale milky white, talcum-filled PTFE backup rings are uniform ash gray, EPDM static rubber fittings are matte charcoal black, coir fabric wear rings are warm yellowish brown.

Q: What core sealing task does extruded PU complete inside the heavy loader’s bucket hydraulic cylinder?
A: As the core reciprocating sealing component, extruded PU relies on stable elastic rebound to lock high-pressure hydraulic fluid inside cylinder cavities and stop leakage when the bucket curls inward and extends outward continuously to scoop massive hard rocks and loose aggregate under irregular ground resistance at heavy-load quarry work.

Q: What is the core design purpose to equip talcum-filled PTFE as auxiliary backup ring matching PU main seal?
A: It fills tiny clearance gaps inside piston mounting grooves and prevents soft PU sealing lip from being extruded and cracked by instantaneous hydraulic pressure spikes generated when the digging bucket suddenly hits compact bedrock or oversized boulders during intensive loading work.

Q: What outstanding practical characteristics make EPDM rubber superior to traditional regular NBR rubber?
A: EPDM has excellent low-temperature flexibility and ultraviolet ageing resistance, maintaining stable sealing tightness after long-term exposure to outdoor wind, dew and alternating hot-cold seasonal temperature changes at open-air raw material yards all year round.
