Adapter Straight #8 Flare 1/4in NPT

The Adapter Straight #8 Flare 1/4in NPT from A-1 PRODUCTS is an essential hydraulic and fuel system fitting for serious vehicle builders and performance mechanics. This straight adapter bridges metric flare connections to national pipe thread (NPT) standards, making it indispensable when retrofitting modern fuel injection systems, turbo oil supply lines, or custom hydraulic brake circuits into older platforms or adapting imported components to domestic plumbing standards.

The #8 flare size (3/8-inch OD tubing) paired with 1/4-inch NPT male threads creates a reliable transition between SAE flare-sealed systems and pipe thread ports found on engines, transmission coolers, and aftermarket manifolds. The straight configuration eliminates angle-related fitment complications and pressure drop inefficiencies common with elbow adapters, while the durable construction ensures reliability under vibration and thermal cycling.

Fabricators, restomod builders, and engine swap specialists benefit most from stocking this fitting, as it simplifies the integration of aftermarket performance equipment and custom installations. The SAE flare connections create a metal-to-metal seal that resists leakage better than compression fittings in high-pressure fuel and oil circuits, critical when working with carbureted-to-EFI conversions or turbo installations requiring precise flow rates.
