5. FAQ

Q: Does this kit follow OEM outline style and installation dimension?
A: Every piece keeps OEM original contour and groove size, direct installation without any cutting or polishing on site.

Q: Can you adjust color or material formula for my large repeated order?
A: Standard finished goods keep fixed natural colors; customized formulation and appearance are acceptable for long-term bulk cooperation.

Q: What practical difference exists between cream white and ash grey seals besides color?
A: Ash grey seals add glass bead filler to improve wear resistance against gritty hydraulic oil, cream white PU focuses on stable elastic compression.

Q: Will high temperature storage darken the surface of black rubber gaskets?
A: Minor surface dullness may appear under hot environment, but the change never damages elasticity and sealing capability.

Q: Can this seal kit be mounted on other types of construction equipment?
A: It is tailor-made for machines equipped with 3304/3306 engines and not interchangeable for other equipment models.

Q: Why is the brown accessory designed as cylindrical sleeve instead of flat thin gasket?
A: Tubular structure guides piston rod linear movement and prevents side sway; flat gaskets only seal gaps between fixed metal connecting faces.

Q: Is it feasible to buy individual parts separately instead of full complete kit?
A: Single component supply is available, but full set replacement is more reasonable during overall cylinder overhaul.

Q: What packaging solution do you use to avoid deformation in overseas transportation?
A: Each set is packed in labeled independent plastic pouch, bulk products are loaded into thickened cartons with buffer lining inside.
