Female to Male Extender Fitting; Size M12 x 1.5

The Female to Male Extender Fitting; Size M12 x 1.5 from VIBRANT PERFORMANCE is an essential connector for custom automotive plumbing systems, vacuum lines, and fluid transfer applications in modified vehicles. As a mechanic building turbo kits, fuel systems, or coolant manifolds, you'll recognize this fitting as a critical adapter for situations where two male-threaded components need to connect, or where you need to extend the reach of an existing female port. This precision extender eliminates the need for bulky intermediate fittings and keeps your engine bay layout clean and efficient.

Constructed to strict M12 x 1.5 metric specifications, this fitting ensures leak-free connections in high-vibration environments common to performance builds and track vehicles. The M12 x 1.5 thread pitch is the industry standard for many OEM and aftermarket vacuum, boost, and coolant adapters, guaranteeing compatibility across Vibrant Performance's component line and most modern Asian and European platforms. The compact 3.5-inch overall length provides practical reach without adding excessive complexity to tight engine compartments, while the lightweight 0.068-pound design minimizes parasitic weight. Vibrant Performance's precision manufacturing ensures concentricity and durability under pressure cycling and thermal stress.

Engine builders, turbo installers, and DIY enthusiasts benefit most from stocking this fitting when designing custom boost control systems, coolant reroutes, or vacuum-operated component integrations. Its M12 x 1.5 specification makes it ideal for vacuum distribution blocks, fuel pressure regulators, boost controllers, and intercooler plumbing on inline-four and V6 performance builds. Compatibility spans Japanese platforms (Honda K-series, Nissan SR20/RB series), European platforms (VW/Audi 1.8T), and any modern fuel-injected system using metric M12 ports. Installation is straightforward—simply thread into the female port and attach your male-threaded hose barb or component, ensuring a secure, vibration-resistant connection.
