In the operation of modern industrial equipment, the stability and durability of sealing systems often directly impact overall production efficiency and maintenance costs. Therefore, durable seals are crucial. The TG4 triple-lip oil seal series, a key product line of the DEDE brand, utilizes a multi-faceted protection concept, combining sealing, wear reduction, and contamination prevention. It is suitable for a wide range of industrial machinery and power transmission systems, including pumps, engines, transmissions, hydraulic systems, construction machinery, and energy equipment.
Compared to traditional single-lip or double-lip oil seals, the TG4 triple-lip oil seal series' triple-lip structure creates a layered barrier. The first lip effectively blocks external particles and dust from entering the system; the second lip maintains fluid pressure, preventing lubricant leakage; and the third lip reduces friction and wear over extended operation, extending the life of the seal and adjacent components. This design not only enhances sealing stability but also reduces energy consumption and environmental impact caused by oil leakage.
TG4 seals are available in nitrile rubber (NBR) and fluororubber (FKM), offering excellent elasticity and wear resistance, adapting to temperature fluctuations and dynamic misalignment. Their low coefficient of friction and chemical inertness make them resistant to a wide range of media, including mineral oils, fuels, and some hydraulic fluids.
DEDE is TG4 triple-lip oil seal series was developed with installation convenience in diverse industrial equipment in mind. The standardized outer diameter matches conventional oil seal seats, reducing adjustment time during replacements. Whether for emergency replacements at maintenance sites or assembly in mass production equipment, installation is fast and efficient, minimizing production losses caused by downtime.
