413-04-05-BLK -4 Female to 5/16" 90° Hose Tail

Speedflow SF413-04-05-BLK | -4 AN Female to 5/16" Hose Tail | 90° | Black | 413 Series

The Speedflow SF413-04-05-BLK is a precision-machined -4 AN female to 5/16" hose tail adapter with a 90° angle, in black anodised finish. Part of the Speedflow 413 series 90° hose tail range, this fitting connects -4 AN female ports to standard 5/16" (approx. 8mm) rubber or silicone push-on hose at a right angle — ideal for tight engine bay and chassis routing where a straight hose tail would force an awkward bend in the hose.

Applications

The SF413-04-05-BLK is the go-to choice when a straight hose tail won’t provide clean routing, including:

• Fuel line connections where the hose runs parallel to the fitting face
• Coolant line connections in tight radiator and cooling system builds
• Vacuum and breather line connections to AN-ported components in confined spaces
• Oil breather and catch can line connections requiring a 90° hose exit
• Any -4 AN to 5/16" hose application where a 90° exit angle eliminates hose stress

413 Series (90°) vs 411 Series (Straight) — Choosing the Right Angle

The Speedflow 411 series provides straight AN female to hose tail adapters, while the 413 series provides the same connection at a 90° angle. When the hose runs along the component surface before connecting, a straight hose tail forces a sharp bend immediately after the fitting — stressing the hose and restricting flow. The 413 series 90° angle eliminates this problem, allowing the hose to exit parallel to the component face for a clean, professional result. For straight -4 AN to 5/16" hose tail applications, see our SF411-04-05-BLK listing.

Sold individually. Secure hose tail connections with an appropriate hose clamp in pressurised applications. Compatible with standard -4 AN male fittings and 5/16" ID rubber or silicone hose.
