4. FAQ
Q: What four different core raw materials constitute all sealing components contained within this maintenance repair kit?
A: The full repair set consists of high tear-resistant molded PU, calcined clay mineral powder reinforced PTFE, outdoor weather-proof EPDM elastomer and viscose textile base phenolic resin saturated anti-wear guiding fabric for piston auxiliary support.

Q: What original natural color does each sealing component retain without any artificially blended pigment or outer coating?
A: PU primary dynamic sealing rings are soft shell white, calcined clay-filled PTFE backup rings are uniform light gray, EPDM static rubber fittings are smooth matte black, viscose impregnated fabric wear rings are warm sandy brown.
Q: What core sealing responsibility does molded PU fulfill inside the wheel excavator’s dipper arm hydraulic cylinder?
A: Acting as the central dynamic sealing component, molded PU takes advantage of stable elastic rebound performance to block high-pressure hydraulic fluid leakage when the dipper arm stretches and retracts repeatedly to scoop and unload soil, crushed stone and construction debris amid irregular bumpy ground resistance.
Q: What is the core design purpose of equipping calcined clay-filled PTFE as auxiliary backup rings paired with the main PU seal?
A: It fills microscopic clearance gaps inside piston installation grooves and protects soft PU sealing lips from being extruded and fractured by sudden hydraulic pressure spikes triggered when the dipper bucket abruptly hits compacted hard soil or buried concrete fragments during digging operations.
Q: What outstanding practical characteristics make EPDM rubber stand out compared with conventional general NBR nitrile rubber?
A: EPDM delivers exceptional cold flexibility and anti-ultraviolet ageing capability, keeping consistent sealing tightness after long-term exposure to outdoor wind, dew and alternating seasonal temperature changes on open-air construction job sites.
Q: At which precise fixed assembly positions of the cylinder are EPDM rubber O-rings commonly installed?
A: EPDM rubber parts are mainly deployed for static sealing on cylinder end cover joint planes and threaded connection gaps of auxiliary hydraulic pipelines exposed to outdoor rainwater and floating construction dust all day long.
