5. FAQ
Q: What natural original color does each sealing component keep without artificial pigment blending or outer paint coating?
A: Compression molded PU main dynamic seals are clean creamy white, bentonite-filled PTFE backup rings are pale taupe gray, HNBR static rubber fittings are fine-textured matte black, kapok fabric wear rings are soft ginger brown.

Q: What core sealing duty does compression molded PU finish inside the excavator’s crowd hydraulic cylinder?
A: As the core reciprocating sealing element, molded PU relies on stable elastic recovery to contain high-pressure hydraulic fluid and avoid internal leakage when crowd arm pulls inward and stretches outward repeatedly to gather piled soil and fragmented rock amid uneven rugged excavation ground.
Q: What is the core design purpose to match bentonite-filled PTFE as auxiliary backup ring alongside PU primary seal?
A: It fills micro interstitial gaps inside piston installation grooves and shields soft PU sealing lip from squeeze rupture caused by sudden hydraulic pressure surges once the digging bucket strikes compact hard subsoil or buried concrete chunks during intensive excavation work.
Q: What outstanding practical merits make HNBR stand out compared with conventional regular NBR rubber?
A: HNBR features excellent anti-hydrolysis and damp ageing resistance, retaining steady sealing tightness after long-term exposure to dew, intermittent rainwater and water-contaminated degraded hydraulic oil under humid all-year outdoor construction environments.
Q: At which fixed stationary cylinder positions are HNBR rubber sealing parts arranged for installation?
A: HNBR components are mainly applied for static sealing on cylinder end cover flange planes and threaded auxiliary hydraulic pipeline gaps prone to invisible slow oil seepage and external damp infiltration.
