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 main functions does this piston seal ring achieve?
A: It supports piston assembly, isolates metal contact and reduces friction loss inside hydraulic cylinders.

Q: What hydraulic pressure range can this PTFE version withstand?
A: It performs steadily under high-pressure hydraulic systems. Nylon material alternatives fit medium-pressure working environments.

Q: Can the product sustain continuous reciprocating movement all day long?
A: Absolutely. Filled PTFE material brings outstanding lubricity and wear resistance under repeated movement.

Q: Are the items sold separately or packed as full repair kits?
A: Single-piece supply is available, and we can combine various sealing parts into matched maintenance kits.

Q: What types of hydraulic fluid can this sealing ring adapt to?
A: It is compatible with mineral hydraulic oil and many synthetic hydraulic fluids, wider medium compatibility than nylon products.

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.
