Turbosmart BOV Kompact O-ring / Gasket Kit
The exact seals to bring your Kompact blow-off valve back to a perfect, boost-tight seal.
Everything You Need to Reseal the Valve
Blow-off valve seals take abuse. Every time you pull the valve to inspect it, re-clock the outlet, or swap a spring, the O-rings get stretched, pinched, or scraped against the housing. A single nicked seal is all it takes to bleed boost past the valve — and that shows up as soft throttle response, a lazy valve report, and a check-engine light for a boost-pressure fault.
This Turbosmart Kompact service kit packs the full set of replacement O-rings and gaskets so you can freshen the entire valve in one shot instead of hunting for a single seal that won't seat right.

🔧 When to Use This Kit
Reach for a fresh seal kit any time you disassemble the valve, chase a boost leak, notice a hissing or fluttering valve, or spot flat/cracked O-rings during inspection. Rubber hardens and takes a set over time and heat cycles — proactively reseal during any BOV service and you'll never chase a mystery leak later.
Genuine Turbosmart, Not Generic Rubber
These aren't generic O-rings pulled from a bin. Each seal in this kit is cut to the exact size, cross-section, and material spec Turbosmart engineered for the Kompact platform, so they seat correctly in the grooves and hold up to the heat and pressure cycling of a forced-induction engine bay. That's the difference between a valve that seals for years and one that weeps at the next heat cycle.
