Ever faced issues with oil leakage or dust infiltration in rugged environments? A TG4 oil seal might be the solution you're looking for. This double-lip shaft seal is specifically engineered for applications requiring superior grease retention and dirt resistance.
What is a TG4 oil seal used for?
A TG4 oil seal is used to protect mechanical systems by sealing lubricants inside and keeping contaminants out. Unlike basic shaft seals, it features a dual-lip design with a rubber-coated metal shell, making it perfect for:
- Off-road machinery
- Gearboxes and reducers
- Electric motors in dusty environments
- Agricultural and construction equipment
The inner lip retains oil or grease, while the outer dust lip blocks external debris. Its rubberized shell improves vibration damping, allowing better sealing even in slightly imperfect bores.
How does TG4 differ from TC oil seals?
Though both are double-lip rotary seals, TG4 and TC differ in design and application suitability:
| Особливість | Сальник TG4 | Сальник TC |
|---|---|---|
| Outer Shell | Сталевий корпус з прогумованим покриттям | All-metal shell |
| Sealing Fit | More forgiving on rough surfaces | Requires smooth bore |
| Vibration Control | High due to rubber casing | Помірний |
| Найкраще для | Dusty, rugged, vibrating environments | Clean, high-speed applications |
For more on TC seals, check our TC Oil Seal Guide.
What are the best applications for TG4 shaft seals?
TG4 oil seals thrive in environments where oil retention and contamination exclusion are critical. Common applications include:
- Industrial fans and blowers
- Construction vehicle drive shafts
- Small engines operating in dusty zones
Their double-lip structure provides enhanced durability over single-lip designs, which are prone to quicker wear in aggressive settings. For a broader view, refer to our Skeleton Oil Seal Selection Guide.
What materials are TG4 oil seals made from?
Material selection impacts chemical resistance and temperature stability. Hengoseal manufactures TG4 seals in:
| матеріал | Температурний діапазон | Найкраще використовувати в |
|---|---|---|
| NBR | від -40°C до +120°C | General-purpose industrial use |
| FKM | -30°C до +200°C | High-temp or chemically harsh systems |

How do you install a TG4 oil seal properly?
Incorrect installation is a leading cause of premature seal failure. Here’s how to install TG4 seals correctly:
- Lubricate the sealing lip before fitting
- Align the seal with the shaft, using a press or seal driver
- Ensure the dust lip faces outward
- Avoid damaging the rubber coating during installation
