RaceFlux PCV & Fuel Check Valve, Nylon 66, 3/8" (10mm) Barb

One-way flow for PCV and fuel plumbing: this nylon 66 check valve carries 3/8" (10mm) barbs on both ends and lets flow pass in one direction only — stopping boost from pressurizing the crankcase through a PCV line, preventing fuel drain-back, and keeping vapors moving the right way in catch can systems.
