DXTSEALS offers a comprehensive range of high-quality metal O-rings to ensure secure and reliable sealing for vacuum, gases, and liquids. Our metal O-rings are engineered to perform exceptionally well, even under extreme conditions. These static and metallic sealing elements can withstand ultrahigh vacuum environments and pressures of up to 5500 bar.
Designed for durability and versatility, DXTSEALS metal O-rings are suitable for a wide temperature range, spanning from -269 degrees Celsius to +750 degrees Celsius. If you need higher temperature applications, please contact our team. Furthermore, our rings exhibit excellent resistance to radioactive radiation, chlorides, corrosion, and other aggressive substances. Our metal O-rings retain superior performance over time and show no signs of aging during usage and storage.
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.
