Fragola Performance Systems 583704 -4 AN 45-Degree Bulkhead Fitting Steel

The Fragola Performance Systems 583704 is a -4 AN (AN4) 45-degree male flare bulkhead fitting constructed from high-quality steel with a zinc plating finish. Designed for use in racing and high-performance automotive plumbing applications, this fitting provides a secure, leak-free connection through bulkhead panels such as firewalls, floors, and chassis walls.

Fragola Performance Systems manufactures their fittings to exacting standards, and the 583704 is no exception. The 45-degree angle allows for cleaner routing of brake, fuel, or oil lines in tight spaces where a straight fitting would create unwanted stress on the hose or line. The zinc-coated steel construction delivers durability and corrosion resistance in demanding race environments.

Key Features:

• -4 AN (AN4) male flare thread size
• 45-degree angled configuration for tight-space routing
• Steel construction with zinc plating for corrosion resistance
• Bulkhead-style design with included bulkhead nut for panel mounting
• Manufactured to exacting tolerances for tight, leak-free connections
• American-made by Fragola Performance Systems in their Connecticut facility
• Compatible with IMCA, USRA, NHRA, and other sanctioned racing applications

The Fragola 583704 is sold individually and is an excellent choice for routing brake lines, fuel lines, or oil lines cleanly through a firewall or chassis panel in any race or performance build.
