1. Product Advantages
The TG4 Skeleton Oil Seal from Forever Seals redefines sealing reliability with its dual anti-leakage design—3 built-in lips block internal fluid seepage, while external circular threads prevent external spillage. Crafted from premium NBR (excellent oil/wear resistance) or FKM (high-temperature tolerance: -20℃ to 280℃), it withstands harsh conditions without compromising performance. Its durable construction extends service life, reducing maintenance frequency and operational costs for users. Plus, the user-friendly design ensures quick, hassle-free installation, minimizing equipment downtime.
2. Working Principle
This seal operates on a multi-layer protection mechanism: the inner lips form a tight seal against the rotating shaft, stopping oil or fluid from leaking inward; the outer threads create an additional barrier, blocking dust, dirt, and other contaminants from entering the equipment. The rigid skeleton inside maintains the seal’s shape, even under high pressure or vibration, ensuring consistent contact with the shaft and housing. This synergy of structure and material guarantees long-term, stable sealing performance.
3. Product Details
Material Quality: Forever Seals selects food-grade, non-toxic NBR and FKM materials, complying with international industry standards to avoid material degradation or harmful emissions.
Sealing Structure: The 3-lip design (vs. 1-2 lips of traditional seals) enhances contact density, while the external threads are precision-machined for uniform spacing, maximizing dust and leakage resistance.
Durability: Under standard operating conditions, the seal’s wear rate is 30% lower than conventional models, thanks to its reinforced rubber compound and anti-aging treatment.
4. Application Range
Ideal for diverse industries and equipment, including:
Industrial machinery: Hydraulic cylinders, gearboxes, motors, and transmission systems.
Automotive & commercial vehicles: Engine components, axle systems, and fuel pumps.
Specialized sectors: Petrochemical machinery, textile equipment, ship engines, and forging machines. It adapts to both low-speed and high-speed rotating parts, meeting multi-scenario sealing needs.
5. FAQ
Q: Can the TG4 seal be used in high-temperature environments?
A: Yes. The FKM version tolerates temperatures from -20℃ to 280℃, suitable for high-heat equipment like engine compartments or industrial furnaces.
Q: How to ensure proper installation?
A: Clean the shaft and housing surface before installation, avoid sharp tools that damage the lips, and ensure the seal is aligned with the shaft—Forever Seals provides a free installation guide for customers.
Q: What is the service life of the TG4 seal?
A: Typically 2-3 years under normal use (varies by working conditions); regular inspection and maintenance can extend its lifespan.
