Replacement Pressure Sea l O-Ring for Part #11493

The Replacement Pressure Seal O-Ring for Part #11493 is a critical wear component designed for the VIBRANT PERFORMANCE 4-inch V-Band clamp system. This precision elastomer seal maintains a leak-free connection in high-pressure applications where vibration and thermal cycling demand reliable sealing integrity. Whether you're rebuilding a turbo intercooler line, exhaust manifold connection, or custom intake system, this o-ring restores the pressure-sealing capability of your original clamp assembly.

Manufactured from FKM (fluorocarbon) elastomer, this o-ring exhibits superior chemical resistance and thermal stability compared to standard Buna-N compounds, making it ideal for applications exposed to fuel, coolant, and exhaust gases at elevated temperatures. The 4-inch nominal size is engineered to fit the groove geometry of VIBRANT's V-Band clamp design, ensuring consistent radial compression and axial retention across the clamp face. FKM material maintains elasticity across a wider temperature range, resisting hardening and degradation that would cause seal failure during repeated heating cycles.

This o-ring is ideal for performance enthusiasts, tuners, and shops rebuilding turbo systems, supercharger plumbing, or modular exhaust configurations. Installation is straightforward—simply remove the worn o-ring from the clamp groove and seat the new seal by hand before re-clamping. Compatibility is assured with all VIBRANT PERFORMANCE 4-inch V-Band clamps carrying the #11493 designation. Stock a replacement now to avoid downtime when pressure seals degrade.
