Male 1/16in NPT to 1/4in Barb Straight Fitting

The Male 1/16in NPT to 1/4in Barb Straight Fitting by VIBRANT PERFORMANCE is an essential adapter for fluid transfer systems in custom automotive builds, forced induction setups, and auxiliary cooling circuits. This fitting bridges two common hose connection standards—National Pipe Thread (NPT) ports and barbed quick-connect systems—allowing you to integrate premium hose assemblies into factory or aftermarket manifolds, catch cans, and boost controllers without costly custom fabrication. Whether you're plumbing a complex turbo recirculation system, connecting PCV breather lines, or routing coolant bypass circuits, this straight configuration eliminates unnecessary bends and pressure drop while maintaining leak-free seals under boost.

Constructed to VIBRANT PERFORMANCE's rigorous standards, this fitting features a precision-machined male NPT thread on one end and a quarter-inch barbed nipple on the other, ensuring reliable engagement with both NPT-threaded ports and reinforced fuel-grade or coolant hose. The straight design minimizes flow restriction and vibration-induced fatigue at connection points—critical when managing boost pressures or high-temperature coolant flows. NPT threads provide a tapered, self-sealing interface that tightens under system pressure, while the barb geometry locks hose firmly in place without requiring additional clamps in low-pressure applications. The compact, lightweight profile (0.015 lbs) suits tight engine bay layouts and OEM cavity spacing without adding bulk.

This adapter is ideal for tuners, engine builders, and performance shops tackling intake manifold porting, turbocharger plumbing, or fuel system upgrades on forced induction platforms. It's equally valuable for street and race applications where factory fittings require replacement or where aftermarket components demand intermediate sizing. Always wrap NPT male threads with PTFE tape before installation to enhance sealing integrity, and verify hose ID compatibility with the 1/4in barb to ensure proper fit and vibration resistance during high-load engine operation.
