4. FAQ

Q: Can this piston seal ring adapt to hydraulic cylinders of all construction equipment?
A: It is specially matched for grader lift cylinders. It cannot be installed on excavator stick cylinders or wheel loader tilt cylinders.

Q: What pressure level can the nylon material withstand steadily?
A: Glass fiber reinforced nylon fits medium pressure hydraulic systems. PTFE composite material works better under continuous high pressure.

Q: Can the product operate stably under frequent reciprocating movement?
A: Sure, the added glass fiber improves rigidity and abrasion resistance for long-time repeated movement conditions.

Q: Are these goods sold separately or assembled into repair kits?
A: Single-piece supply is supported, and we can combine different sealing accessories into matched maintenance packages.

Q: What hydraulic media can this guiding ring adapt to?
A: It works well with common mineral hydraulic oil. PTFE alternatives have stronger tolerance for synthetic hydraulic fluids.

Q: What suggestions do you have for long-term storage of these plastic rings?
A: Keep them in cool and dry warehouse. Avoid high temperature environment and prolonged sunlight exposure. Different polymer materials should be stored separately.

Q: Are these goods sold separately or assembled into repair kits?
A: Single-piece supply is supported, and we can combine different sealing accessories into matched maintenance packages.

Q: What core function does this piston seal ring perform inside the cylinder?
A: It separates high-pressure and low-pressure oil chambers inside the cylinder and prevents hydraulic fluid from flowing across both sides of the piston.

Q: What engineering projects commonly require replacement of this piston seal ring?
A: It serves routine maintenance of hydraulic cylinder piston sealing assemblies on medium crawler excavators, widely used in urban infrastructure, highway subgrade construction, small quarry loading and residential foundation excavation projects.
