O-Rings - 2007 Buna 70 (NE-76) 10pk

The O-Rings - 2007 Buna 70 (NE-76) 10pk from Penske Racing Shocks are precision elastomer seals engineered for use in high-performance shock absorber assemblies and hydraulic systems. This 10-pack of Buna 70 o-rings delivers the exact replacement specification needed for Penske Racing Shocks maintenance and rebuild work, ensuring proper fluid containment and consistent damping performance across your suspension components.

Buna 70 (nitrile at 70 Shore A hardness) is the industry standard for automotive and motorsports hydraulic applications. This durometer rating provides optimal balance between elasticity and resistance to petroleum-based shock fluids, temperature cycling, and compression set. The 2007 specification matches Penske's original equipment dimensions and material composition, ensuring a direct fit without compatibility issues. A 10-pack quantity supports multiple shock rebuilds or provides backup inventory for competitive teams and suspension shops that maintain Penske Racing Shocks systems regularly.

These o-rings are essential for off-road racing, road racing, drag racing, and performance vehicle builders who rely on Penske shocks for precision damping. Proper seals are critical—degraded or incorrect o-rings lead to fluid weeping, loss of damping consistency, and reduced shock lifespan. Sourcing OEM-specification replacements like this 2007 Buna 70 pack eliminates guesswork and confirms correct fitment during service intervals or build-ups. Teams and technicians trust this designation because it matches the manufacturer's original design tolerances exactly.
