Product Advantages
Superior Material Performance: Crafted from high-grade FKM by FOREVER SEALS, our VA seal offers exceptional resistance to extreme temperatures (-20℃ to 200℃, with special formulations up to 260℃). It can withstand aggressive chemicals, fuels, and oils, outperforming standard rubber seals in harsh environments. FOREVER SEALS' strict material selection ensures long - lasting quality.
Enhanced Sealing Reliability: FOREVER SEALS designs the pressure-activated lip of the VA seal to ensure a tighter seal as system pressure increases. This minimizes leakage risks even in dynamic operations like reciprocating or rotating motions, providing stable sealing performance.
Longevity & Cost-Efficiency: With excellent anti - aging, ozone, and wear resistance, FOREVER SEALS' VA seal has an extended service life. This reduces replacement frequency and maintenance costs over time, bringing cost - effectiveness to your operations.
Working Principle
FOREVER SEALS' VA seal operates on a pressure - actuated sealing mechanism. Its lip - shaped design has an initial interference fit with the mating surface, creating a baseline seal. When system pressure is applied, the fluid pressure forces the lip to deform outward, increasing contact pressure with the sealing surface. This dynamic response ensures a tighter seal as pressure rises, effectively preventing fluid leakage in both static and dynamic applications. The FKM material's elasticity, carefully selected by FOREVER SEALS, maintains consistent lip contact, even under temperature fluctuations or minor surface irregularities.
Product Details
Structure: FOREVER SEALS precision - machines the VA lip seal with a robust cross - sectional design. This is optimized for uniform pressure distribution across the sealing surface, ensuring reliable sealing.
Material Grade: We offer medical and industrial - grade FKM options, all meeting international standards (e.g., ISO, ASTM) for quality and safety. FOREVER SEALS is committed to providing high - quality materials.
Dimensions: Our VA seals come in customizable sizes (diameters, thicknesses) to fit specific equipment requirements. We maintain tight tolerances for seamless installation, thanks to our advanced manufacturing technology.
