Kompact Universal Plumb Back Valve 25mm Black

The Kompact Universal Plumb Back Valve 25mm Black is a precision blow-off valve engineered for turbocharged and supercharged engine systems that require reliable boost pressure management. This universal valve is designed for builders and enthusiasts who need a compact solution to vent excess boost pressure safely back into the intake system, preventing compressor surge and protecting engine integrity. Whether you're tuning a street application or optimizing a performance build, this plumb-back configuration offers flexibility in mounting and integration across multiple engine platforms.

Constructed from black anodized aluminum, the Kompact Universal Plumb Back Valve features 25mm inlet and outlet ports that accommodate standard boost piping configurations with minimal restriction. The plumb-back design routes vented boost directly back to the intake manifold or turbo inlet, eliminating the need for external atmosphere venting and reducing compressor noise while maintaining boost consistency. The anodized aluminum construction provides corrosion resistance and durability under high-temperature engine bay conditions, while the compact footprint allows installation in space-constrained engine compartments without sacrificing functionality or reliability.

This universal valve suits builders working with turbocharged four-cylinder, V6, and V8 applications where boost control and intake surge management are critical. Plumb-back valves are preferred in street and track builds where noise suppression and boost stability matter equally; the closed-loop design prevents atmospheric venting and maintains consistent air-fuel ratios under transient throttle conditions. Installation requires basic piping knowledge and standard hose clamps or barbed fittings compatible with 25mm tubing—making it an accessible upgrade for both experienced tuners and first-time boost system builders seeking a proven, compact solution.
