RaceFlux Straight Bulkhead Adapter Fitting

Running a line through a firewall, trunk floor, or body panel without a bulkhead fitting is asking for chafed hose and leaks. This RaceFlux straight bulkhead adapter passes the connection cleanly through the panel with a male 37-degree AN flare on each side, so you terminate a hose end on either face of the panel and the fitting takes the abuse instead of the line.

CNC-machined from 6061-T6 aluminum with a Type II black anodized finish and rated to 500°F, it handles everything from fuel system pass-throughs to hot-side oil plumbing.
