TvnSeal Engineering Plastics Technology Co., Ltd. is a national high-tech enterprise specializing in the R&D and manufacturing of high-performance sealing materials and special polymer new materials.
Dust wipers are generally secured inside the housing by pressure plate flanges, mainly serving as replacement components for legacy hydraulic and pneumatic cylinders or for secondary operating conditions.

| Surface Roughness | Rtmax | Ra |
| Sliding Surface | ≤ 2.5μm | ≤ 0.1-0.5μm |
| Groove Bottom | ≤ 6.3μm | ≤ 1.6μm |
| Groove End Face | ≤ 15μm | ≤ 3μm |
| Additional Notes: Support Rate: 50-95%, Cutting Depth 0.5R (based on the reference condition of Cref=0%) | ||
| Recommended Dimensions (mm) |
| Minimum nominal inner diameter d ≥ 6 mm. This is a non-standard cross-section, suitable for replacement of existing installation space. Standard cross-sections are recommended for new designs. |
