Str Alum #4 Flare 1/4in Black

The Str Alum #4 Flare 1/4in Black is a critical hydraulic fitting engineered for high-pressure brake and fuel line applications in performance and street vehicles. As a mechanic working on custom builds, you know that undersized or inferior fittings are a common failure point—especially when upgrading to larger displacement engines or aggressive braking systems. This AEROQUIP aluminum flare fitting delivers the reliability required when stock plumbing won't cut it, whether you're building a track car, restomod, or daily driver with serious modifications.

AEROQUIP's aluminum construction strikes the balance between weight savings and durability that modern performance builds demand. The 1/4-inch flare connection creates a leak-free seal under extreme pressure without thread sealant tape—critical when life safety depends on brake or fuel integrity. The black anodized finish resists corrosion and maintains appearance in engine bays, while the SAE flare geometry ensures compatibility with industry-standard tubing adapters and hose ends. This size and configuration handles fuel delivery and brake line duties across a wide range of displacement and brake horsepower levels without compromise.

Builders upgrading carburetor fuel systems, EFI conversions, and high-performance brake setups rely on this fitting to transition between rigid tubing runs and braided stainless hose. Its compact 2.35 x 1.1 x 3.7-inch footprint and featherweight 0.04-pound design mean zero impact on vehicle dynamics or packaging constraints. Install with a flare nut wrench to avoid deforming the fitting body—overtightening is the enemy of aluminum fittings. Whether you're sourcing individual components for a complete system rebuild or replacing a failed original part, this AEROQUIP fitting delivers OEM-grade performance at competitive pricing.
