Str Alum #8 Flare 1/4in Black

The Str Alum #8 Flare 1/4in Black is a precision aluminum brake line fitting engineered for hydraulic brake systems in high-performance vehicles and custom automotive builds. As a mechanic upgrading brake systems or fabricating custom hydraulic circuits, you'll recognize this AEROQUIP component as essential for reliable fluid transfer under pressure. This fitting serves applications where OEM brake hoses fall short—custom engine bays, modified suspension setups, and competition vehicles demanding stainless steel or braided brake line routing that requires flare-style connections.

Built from lightweight aluminum, the #8 flare fitting accommodates 1/4-inch brake line with a standard 37-degree JIC flare connection—the industry-standard thread angle that ensures leak-free seals under repeated brake pressure cycles. The black anodized finish provides corrosion resistance while reducing visible hydraulic line degradation from road salt, moisture, and UV exposure common in performance driving environments. The flare design eliminates the need for compression fittings or adapters on properly sized steel or stainless brake lines, delivering a compact, clean installation with minimal weight penalty—critical for weight-sensitive builds where every fraction of a pound matters.

Enthusiasts fabricating custom brake line runs, installing upgraded master cylinders, or converting to remote fluid reservoirs benefit from having multiple sizes of AEROQUIP fittings on hand. The 1/4-inch bore size pairs with -8 AN (equivalent to 1/2-inch NPT) brake line commonly used in street performance, track, and drag racing applications. Installation requires no special tools beyond a wrench for final torque—simply mate the flared line end to the fitting body and tighten to specification. Verify your brake line flare diameter and thread pitch before ordering; this fitting is designed for 37-degree JIC flare connections and will not function with 45-degree SAE flare lines.
