10mm O.D. Vacuum Line Fi tting

The 10mm O.D. Vacuum Line Fitting from Vibrant Performance is a precision-engineered vacuum system component designed for vehicles requiring reliable emission control and engine management connections. Built for technicians and enthusiasts who demand durability in critical vacuum routing applications, this straight fitting bridges 10mm tubing to 3/8-inch hose barb configurations—a common specification in both OEM and modified engine setups. Whether you're restoring a classic platform, rebuilding a fuel-injected engine, or troubleshooting vacuum leaks, this fitting serves as a fundamental building block in proper fuel delivery and emission regulation systems.

Manufactured from aluminum and finished in natural (unpainted) condition, the 10mm O.D. Vacuum Line Fitting incorporates a reinforced rubber grommet that prevents vibration-induced loosening and reduces the risk of vacuum line separation during engine operation. The straight design eliminates unnecessary routing angles, maximizing flow integrity and minimizing pressure drop across the connection point. At 1.50 inches in length, this fitting provides adequate seating depth for both the tubing and hose barb interfaces without requiring excessive adapter complexity—critical when space is limited in tight engine compartments. The barbed end ensures positive grip on rubber hose, preventing leaks that would compromise fuel atomization and engine efficiency.

This fitting benefits mechanics, engine builders, and restoration specialists who prioritize sealed vacuum systems and repeatable fuel delivery calibration. Installation is straightforward: slip the 10mm tubing over the barbed end, secure with hose clamp if needed, and connect to your vacuum port. The rubber grommet accommodates slight vibration and thermal cycling without material fatigue. Ideal for EFI conversion kits, carburetor secondary vacuum lines, brake booster circuits, or emission device routing, the 10mm O.D. Vacuum Line Fitting is an essential consumable for anyone maintaining or modifying fuel-injected powerplants.
