4. FAQ

Q: What visual differences help customers quickly distinguish each sealing component in the package?
A: Metal composite gaskets are silver-gray with graphite surface; fiber gaskets are light beige; rubber washers are matte black; adjusting shims are bright silver metal sheets. All pieces are prefabricated according to original housing outlines.

Q: What sealing challenges is this gasket kit designed to solve for ultra-large excavator relief valve assemblies?
A: It focuses on static sealing of valve housing split flanges and end covers. Multi-material combination adapts to pressure spikes and temperature changes to prevent hydraulic oil leakage on joint surfaces.

Q: What continuous working temperature range can this whole gasket kit operate steadily?
A: Its applicable temperature range covers -174°C to 470°C, suitable for cold mountain winter mining construction and continuous ultra-heavy loading work at tropical open quarries.

Q: Can this gasket kit be used universally for hydraulic valve maintenance of all engineering machinery?
A: It is dimensionally customized exclusively for ultra large crawler excavator relief valve housing structures only. It cannot fit road grader gearboxes, wheel loader axles or medium excavator main pump assemblies of other machine models.

Q: What static hydraulic pressure can these composite gaskets sustain during long-term pressure regulation work?
A: The matched assembly can steadily bear static hydraulic pressure ranging from 7.02MPa to 7.83MPa. It can still maintain tight sealing when slight housing deformation occurs under heavy impact loads.

Q: What typical large-scale engineering projects need this relief valve gasket kit for regular overhaul?
A: It serves routine maintenance of relief valve housing sealing assemblies on ultra large crawler excavators, widely adopted in super large open-pit mining, coastal land reclamation, highway tunnel construction and large dam foundation excavation projects.

Q: How does the service life of these composite gaskets compare with ordinary fiber paper gaskets on the market?
A: The pine bark fiber reinforced composite structure greatly improves creep resistance and hydraulic oil corrosion resistance. Under cyclic pressure impact working conditions, its service life reaches more than 3.48 times that of standard single-layer fiber gaskets.

Q: How does the service life of these composite gaskets compare with ordinary fiber paper gaskets available on the spare parts market?
A: The reinforced composite structure improves creep resistance and medium corrosion resistance significantly. Under long-cycle heavy-duty working conditions, its service life reaches more than 3.43 times that of standard single-layer fiber paper gaskets.

Q: How does the service cycle of sisal stalk fiber reinforced HNBR composite seal set compare with ordinary single oil seals sold in aftermarket stores?
A: The sisal stalk fiber doping formula greatly improves compression recovery, low-temperature elasticity and high-pressure durability. Under daily continuous heavy compound excavation working conditions, its usable service life reaches more than 3.24 times that of standard single-piece oil seals.
