-12an Male Aluminum Weld-In Fitting

The MEZIERE -12AN Male Aluminum Weld-In Fitting is an essential component for those involved in custom fuel, coolant, and hydraulic system fabrication. This fitting is designed for fabricators and engine builders who require reliable, leak-free connections in their projects, such as race vehicles, custom truck fuel systems, and high-performance hydraulic installations.

Constructed from aluminum, this weld-on bung is lightweight yet strong enough to handle moderate pressure applications. It accepts 12 AN male hose fittings and is engineered for permanent installation, requiring TIG or oxy-acetylene welding to ensure a secure connection. The natural aluminum finish is compatible with most coolants and petroleum-based fluids, although users should verify compatibility with specialty fluids.

Ideal for custom cooling systems and fuel system modifications, this fitting provides a fixed, sealed connection that eliminates issues associated with threaded fittings, such as fatigue and vibration-induced loosening. Its design follows industry-standard SAE port sizing, ensuring compatibility with readily available 12 AN hose assemblies, adapters, and fittings, making it a valuable addition to any fabrication toolkit.
