411-06-BLK -6 Female to 3/8" Hose Tail

Speedflow 411-06-BLK | -6 AN Female to 3/8" Hose Tail | Black

The Speedflow 411-06-BLK is a precision-machined -6 AN female to 3/8" hose tail adapter in black anodised finish, designed to connect -6 AN female fittings to standard 3/8" (approx. 10mm) rubber or silicone hose in performance fuel, coolant, oil, and hydraulic line builds. A step up in flow capacity from the -4 AN 411-04-05-BLK variant, the 411-06-BLK is the preferred choice for higher-flow applications where -6 AN lines interface with conventional push-on hose.

411 Series — AN Female to Hose Tail

The Speedflow 411 series bridges the AN braided line world and conventional rubber or silicone push-on hose — essential in builds where both hose types are used. The 3/8" barbed hose tail grips securely to push-on hose, while the -6 AN female end connects to any standard -6 AN male fitting. The black anodised finish delivers a premium, consistent aesthetic across your build. Always secure hose tail connections with an appropriate hose clamp in pressurised applications.

Sold individually. Compatible with standard -6 AN male fittings and 3/8" ID rubber or silicone hose.
