Applications

The SF320-03 is a staple fitting for performance and motorsport builds requiring clean panel pass-throughs, including:

• Brake line firewall pass-throughs in hot rods, race cars, and custom builds
• Clutch hydraulic line bulkhead routing
• Fuel line firewall and chassis panel pass-throughs
• Oil and coolant line routing through bulkheads in race car builds
• Any application requiring a secure -3 AN line pass-through a panel or chassis member

Why Use a Bulkhead Fitting?

Routing AN lines directly through a hole in a firewall or chassis panel without a bulkhead fitting risks chafing, vibration damage, and an unprofessional finish. The SF320-03 bulkhead fitting clamps securely to the panel using the supplied nut, providing a fixed, vibration-resistant anchor point that protects the line and gives your build a clean, race-ready appearance. It also makes line removal and replacement significantly easier during servicing.
