Union Sleeve Replacement For HD Clamp Assembly

The Union Sleeve Replacement for HD Clamp Assembly by Vibrant Performance is a critical wear component designed to restore integrity to heavy-duty turbocharger and supercharger inlet systems. As a mechanic working on boost-equipped vehicles, you'll recognize this sleeve as the interface component that maintains a pressure-tight seal between the clamp assembly and intake ducting. Whether you're servicing a rebuilt turbo installation, addressing boost leaks on a modified engine, or restoring OEM clamp functionality after miles of service, this replacement sleeve delivers the reliability needed for consistent boost delivery and engine performance.

Engineered from durable elastomer material, the union sleeve absorbs vibration and thermal cycling while maintaining compressive force under sustained boost pressure. The compact design—measuring 7.05 inches in length with a 1.25-inch outer diameter profile—fits standard HD clamp assemblies without requiring adapter plates or modifications to existing intake piping. Vibrant Performance's precision manufacturing ensures tight tolerances that prevent slippage and micro-leaks, common failure modes when using worn or undersized replacement sleeves. The lightweight construction at just 0.08 pounds minimizes unsprung mass while the elastomer compound resists degradation from oil vapor, coolant spray, and temperature extremes typical of intercooler piping environments.

This replacement sleeve is essential for turbocharged and supercharged builds running 15+ PSI of boost, where even minor air leaks compound into measurable losses in engine response and peak power. Installation takes minutes—simply unbolt the clamp assembly, slide out the worn sleeve, and install the new unit without breaking turbo or intercooler connections. Mechanics and enthusiasts building LS turbos, 5.0 Coyote blowers, or domestic diesel applications will find this component indispensable for maintaining factory-tight seal integrity. Verify clamp assembly bore dimensions match the 1.25-inch profile before ordering to ensure proper fit with your specific intake configuration.
