1. Product Introduction
This high-temperature TC oil seal uses FKM as the sealing material, retaining the classic double-lip
skeleton structure of TC type, and is specially optimized for
high-temperature, high-oil-consumption and harsh chemical
environments. It is mainly used in high-load engines,
high-temperature hydraulic systems, construction machinery,
generator sets and other equipment that requires long-term stable
operation under high temperature conditions. It is the preferred
sealing solution for global high-end equipment.
2. Structural Upgrades
- Stainless steel skeleton : High temperature resistance, no oxidation, no deformation,
suitable for long-term high-temperature environment.
- High-temperature resistant double lip: Thicker and reinforced lip structure, with anti-extrusion and
anti-aging properties.
- Inconel high-temperature spring: Maintains elasticity at 230°C, no relaxation, no fracture.
- High-temperature adhesive bonding: Ensures no delamination between rubber and insert under thermal
shock.
- Hydrodynamic lip design: Improves oil return capacity and reduces lip temperature.
