AN12 Bulkhead Fitting — Anodised Alloy

A lightweight anodised alloy AN12 (-12 AN / 12 JIC) bulkhead fitting for passing high-flow fluid lines cleanly through a bulkhead, firewall, or panel. AN12 is commonly used for oil drain lines, dry sump systems, oil tank connections, and large-bore coolant lines where maximum flow rate is required. Provides a secure, leak-free connection point where a hose line needs to transition through a chassis panel.

What is a Bulkhead Fitting?

A bulkhead fitting is designed to pass a fluid line through a panel, bulkhead, or firewall. The fitting mounts through a drilled hole in the panel and is secured with a bulkhead lock nut, providing a fixed connection point on each side of the panel. This allows hose ends to be connected on both sides for a clean, professional installation without the hose passing loosely through the panel. See our AN12 Bulkhead Lock Nut to complete the installation.

Fitment & Compatibility

Compatible with all standard AN12 hose ends and fittings. Secure with our AN12 Bulkhead Lock Nut (1-1/16" UNF). For other AN sizes, see our full range of AN bulkhead fittings.
