Str Bulkhead Fitting #3

The Str Bulkhead Fitting #3 from FRAGOLA is a precision-engineered AN hydraulic fitting designed for high-pressure fluid line applications where space constraints or installation geometry requires a bulkhead pass-through configuration. This 3 AN straight bulkhead fitting connects two separate fluid circuits or sealed compartments with a reliable seal, making it essential for custom automotive fuel systems, hydraulic brake lines, and competition vehicle plumbing where direct in-line connections are impractical or impossible.

Constructed from aluminum with blue anodized protection, this fitting features 3 AN male threads on both ends, allowing it to secure hose ends or adapter fittings from opposite sides of a bulkhead wall or partition. The anodized finish provides corrosion resistance and improves durability in harsh underhood environments while maintaining the lightweight benefits of aluminum construction. The bulkhead design isolates pressure loads from the mounting surface, reducing stress on chassis and tank penetrations and extending system longevity in high-vibration applications.

This fitting is ideal for custom fuel system builders, race car fabricators, and hydraulic system installers who need to route lines through firewalls, tank walls, or custom enclosures without compromising structural integrity. Compatible with all standard 3 AN hose and fitting systems, it simplifies installation in tight spaces where traditional straight fittings would be impractical. Proper AN thread sealant and hose assembly technique ensure leak-free operation under sustained pressure and vibration.
