The 216 BUNA O Ring by Brinn Transmission is a critical fluid-sealing component designed specifically for high-performance transmission systems and hydraulic assemblies. This o-ring is essential for mechanics working with modified and race-oriented powertrains, ensuring pressure integrity in transmission coolers, valve bodies, and pump housings.
Manufactured from BUNA (nitrile) elastomer, the 216 o-ring provides superior resistance to mineral-based and synthetic transmission fluids while maintaining elasticity across a wide thermal range—typically -40°F to +250°F. Its compact dimensions (1.6 x 0.35 x 2.9 inches) allow for precise fitment in tight valve body cavities and pump ports, making it a reliable choice for high-stress applications.
This seal is ideal for anyone performing transmission maintenance, rebuilds, or upgrades specifically on Brinn-equipped systems and compatible aftermarket gearboxes. Its resilience under sustained pressure and compatibility with both conventional ATF and modern full-synthetic formulations make it a preferred choice for technicians focused on performance and reliability.
