Q: What is the OEM part number of this hydraulic dust wiper seal?
A: The OEM part number is VOE14597457, this dust wiper seal is engineered for excavator dipper arm cylinder outer dust scraping protection.

Q: What construction machine can part VOE14597457 be installed and matched on?
A: VOE14597457 fits excavator dipper arm hydraulic cylinder and acts as the outermost scraper for reciprocating piston rod.

Q: What raw materials are used to produce this dust wiper seal?
A: It adopts PU, HNBR and pressed steel shell, featuring strong scraping edge toughness and stable structural rigidity.

Q: What core function does this dust wiper seal perform for dipper arm hydraulic cylinder?
A: It scrapes away mud, fine rock grit and debris on piston rod before retraction, preventing abrasive particles entering the internal sealing assembly.

Q: Where is this dust wiper seal positioned in the hydraulic cylinder assembly?
A: It is fitted into the outermost slot of rod gland, the first sealing component exposed directly to harsh construction site environment.

Q: What negative effect will appear once this dust wiper seal loses its scraping performance?
A: Hard contaminants will enter cylinder interior and wear inner rod seals gradually, which triggers oil leakage and reduces arm working output.

Q: What product category does VOE14597457 belong to?
A: It belongs to dust wiper seal, an external protective hydraulic spare part for excavator dipper arm cylinder overhaul service.

Q: What benefit does the pressed steel shell bring to this wiper seal?
