Spring Energized Lip Seals
The DXTSEALS spring-energized PTFE seal represents the latest generation of spring-activated Teflon seals. These seals feature a specialized precision jacket/lip crafted from Teflon (or other high-performance polymers) and a corrosion-resistant stainless steel spring.
This unique combination allows the spring to press the seal lips against the gland and rod walls, with the pressure further assisting the spring force. The spring adjusts for lip wear, hardware tolerances, and eccentricities, providing continuous resilience to the seal lips. The DXTSEALS design, with its sealing lip and spring arrangement, offers superior leakage protection compared to traditional lip seals.

TC oil seals, also known as dual-lip oil seals, are widely used in various industrial and automotive applications due to their robust design and superior sealing performance. In this article, we will discuss the key characteristics of TC oil seals and compare them to other types of oil seals, highlighting their advantages in sealing performance, durability, and versatility.
Key Characteristics of TC Oil Seals
1.Dual-Lip Design The most distinguishing feature of TC oil seals is their dual-lip design. TC oil seals are equipped with both a primary lip and a secondary dust lip. The primary lip provides excellent fluid retention, while the secondary lip prevents contaminants such as dirt, dust, and moisture from entering the system. This dual-lip structure enhances the overall sealing performance and protects the internal components from wear and tear.
2.Durability and Wear Resistance TC oil seals are made from high-quality materials like Nitrile Rubber (NBR) and Fluoroelastomer (FKM), which offer excellent resistance to wear, heat, and chemicals. This makes TC oil seals highly durable, allowing them to withstand the harsh operating conditions commonly found in industrial and automotive environments. Their durability ensures a longer service life, reducing the frequency of maintenance and replacements.
3.Superior Sealing Performance The dual-lip design, combined with the use of high-performance materials, provides TC oil seals with exceptional sealing capabilities. They can effectively prevent oil, grease, and other fluids from leaking, while also blocking external contaminants from entering the system. This high level of sealing performance makes TC oil seals suitable for applications where reliability is crucial.
4.Temperature and Chemical Resistance TC oil seals are designed to operate in a wide range of temperatures, making them versatile for different environments. NBR TC oil seals can withstand temperatures from -40�°C to 100�°C (-40�°F to 212�°F), while FKM TC oil seals can endure even higher temperatures, up to 200C (392F). Additionally, TC oil seals are resistant to various chemicals, oils, and fuels, ensuring their effectiveness in challenging industrial applications.
5.Versatility TC oil seals are highly versatile and can be used in a wide range of applications, including automotive engines, industrial machinery, pumps, and gearboxes. Their ability to function in diverse environments, along with their high-performance characteristics, makes them a popular choice in many industries.

NBR and silicone O-ring seals are widely used in hydraulic pumps due to their excellent sealing performance and resistance to various fluids. NBR (Nitrile Butadiene Rubber) offers superior oil and abrasion resistance, making it ideal for high-pressure environments, while silicone O-rings provide outstanding temperature flexibility and durability.
Understanding the key features and applications of these materials can help in choosing the right O-ring for hydraulic systems, ensuring optimal performance and longevity.
