3/8" UNF Female Swivel Nut – Stainless Steel Brake Hose Fitting

The 3/8" UNF female swivel nut is a adjustable end fitting for AN3 braided brake hose, designed to connect to male 3/8" UNF threaded brake ports. The swivel action allows the hose end to rotate freely during installation, ensuring perfect alignment without twisting or stressing the hose — essential for a clean, professional brake line build.

Commonly used on classic British vehicles, older performance cars, and motorsport applications where a female 3/8" UNF connection is required at the caliper, master cylinder, or inline fitting. Available in four angle configurations.

Variants

• Straight – direct fitment for unobstructed runs
• 20° Bend – subtle offset for tight clearances
• 45° Bend – versatile mid-angle routing
• 90° Bend – right-angle fitment, ideal for caliper connections
