4. FAQ

Q: What colors can customers receive for standard in-stock goods?
A: The PTFE wear ring is light grey, and the fluorine rubber back-up ring is dark brown. Custom color options can be negotiated for bulk orders.

Q: Is this piston seal ring suitable for all construction machinery hydraulic cylinders?
A: It is specially designed for grader scarifier cylinders. It cannot fit piston grooves of excavator bucket cylinders or wheel loader lift cylinders.

Q: What construction scenarios fit this sealing component well?
A: It operates reliably in road renovation and ground scarifying projects, adapting to frequent reciprocating movement of scarifier equipment.

Q: What temperature range can this piston seal ring withstand during continuous work?
A: It maintains stable sealing performance within -56°C ~ 138°C under long-time outdoor road construction conditions.

Q: What temperature scope can this piston seal ring withstand during continuous equipment operation?
A: It keeps stable sealing performance between -46°C ~ 136°C under long-time heavy-duty excavation work.

Q: What installation notes should maintenance operators keep in mind?
A: Do not fold or twist the flat seal ring forcibly, and clear all fine dust and metal debris inside the piston groove before assembly.

Q: What core effect does this piston seal ring bring inside the boom cylinder?
A: It separates high-pressure and low-pressure oil chambers and prevents hydraulic fluid cross leakage on two sides of the piston assembly.

Q: Will the seal ring be squeezed and deformed easily under lasting high hydraulic pressure?
A: The fiber reinforced structure improves rigidity, which greatly reduces the risk of extrusion damage under normal circulating pressure.

Q: What installation tips should maintenance technicians follow?
A: Avoid bending the flat seal ring violently during assembly, and clear sediment inside the piston groove completely in advance.

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.
