Product Advantages
Forever Seals'VA NBR seal stands out with NBR (nitrile butadiene rubber) as its core material, boasting excellent oil resistance—a key trait for systems handling fuels, lubricants, and mineral oils. Its VA lip structure ensures reliable sealing under dynamic conditions, adapting to low-speed rotation and reciprocating motions with minimal leakage risk.
Balancing performance and cost, this seal offers strong durability in medium-temperature environments (0℃–120℃) and maintains flexibility for easy installation. Compared to premium materials like FKM, it provides a cost-effective solution for general industrial applications without sacrificing core sealing capabilities.
Working Principle
The VA NBR seal operates on a pressure-actuated mechanism, a design signature of Forever Seals. Its lip features an initial interference fit with the mating surface, creating a baseline seal. When system pressure increases, fluid forces the lip to expand outward, enhancing contact pressure with the sealing surface—ensuring tighter sealing as pressure rises.
NBR's inherent elasticity, paired with the VA structure, maintains consistent lip contact even with minor surface irregularities or temperature fluctuations, making it reliable for both static and low-speed dynamic applications.
