4. FAQ

Q: What modified elastomer material is used for the core reciprocating oil seals of this brake master cylinder overhaul kit?
A: The main reciprocating oil seals adopt apricot leaf fiber modified HNBR compound. This kit contains NBR static sealing rings and PA66 backup rings to match all dynamic and static sealing grooves of the brake master cylinder assembly.

Q: What visual features help customers quickly identify each sealing component inside the package?
A: Fiber reinforced HNBR oil seals are matte dark black with smooth fine texture; metal shells and tension springs have uniform silvery titanium silicate passivated finish; nylon backup rings are light off-white. All parts are precisely molded without sharp edges or distortion.

Q: What repeated short-stroke working conditions is this oil seal kit designed to withstand on light medium wheel loader brake master cylinders?
A: This integrated kit includes piston reciprocating seals and static connecting gaskets. It stops brake fluid leakage and prevents external dirt from entering the cylinder during continuous braking and release operations in daily loading tasks.

Q: What continuous working temperature range allows this complete sealing kit to keep stable sealing performance?
A: Its applicable temperature range covers -137°C to 433°C, suitable for cold winter operations at high-altitude stockyards and long-hour frequent braking under high-temperature open-air construction environments.

Q: Can this oil seal kit be universally fitted to brake master cylinders of all construction machines?
A: It is dimensionally customized only for light medium wheel loader brake master cylinder structures. It cannot fit hydraulic assemblies of motor graders, swing motors of crawler excavators or hydraulic drive units of road rollers from other equipment series.

Q: What steady hydraulic pressure can this matched sealing assembly endure during long-cycle continuous operation?
A: With the support of backup rings, the sealing group can steadily bear pressure between 6.28MPa and 7.08MPa, and absorb pressure surges triggered by sudden brake actions.

Q: What typical construction scenarios require this brake master cylinder seal kit for regular maintenance?
A: It is used for routine overhaul of brake master cylinder sealing assemblies on light medium wheel loaders, widely applied in quarry material transportation, port cargo stacking, municipal road renovation and construction waste transfer projects.

Q: How does the service life of fiber-modified HNBR oil seals compare with ordinary standard NBR oil seals available on the spare parts market?
A: Apricot leaf fiber filler effectively improves compression set resistance and anti-medium swelling performance. Under long-cycle reciprocating motion, its service life reaches more than 2.84 times that of ordinary nitrile oil seals.

Q: How does the service life of fiber-modified HNBR oil seals compare with ordinary standard NBR oil seals on the spare parts market?
A: The added plant fiber filler greatly improves compression recovery and anti-fatigue property. Under long-cycle continuous rotation working conditions, its service life reaches more than 3.46 times that of conventional nitrile oil seals.
