4. FAQ

Q: How many color categories are included inside part 105-3357 seal kit?
A: Four distinct color tones: chestnut brown guide sleeve, off-white main seal, ash gray wear-resistant ring and compact black O-ring gaskets.

Q: What functional differences lie behind these different colored components?
A: Brown fabric sleeve guides piston rod movement; off-white PU seals bear regular dynamic sealing; gray PTFE rings reduce friction; black gaskets fill static assembly gaps.

Q: Is the overall structural style identical to original factory OEM spare parts?
A: We strictly copy OEM size and structural design, all rings fit the original cylinder groove without trimming during installation.

Q: Can you customize different colors or material formulas for bulk purchase?
A: Standard color is fixed by raw material feature; customized formulation and color are negotiable only for large batch orders.

Q: What is the core difference between off-white and ash-gray sealing rings besides color?
A: Ash-gray rings are added with graphite filler to stand higher impact load, while off-white pieces prioritize low friction for smooth reciprocation.

Q: Will continuous soaking in hydraulic oil fade the surface color of these seals?
A: All materials are oil-proof tested; slight darkening after long work is normal and won’t cause color peeling or sealing failure.
