Mishimoto Air To Water Intercooler Fitting -12AN Adapter

Mishimoto Air To Water Intercooler Fitting -12AN Adapter adapts a -12 ORB thread to -12AN, delivering a reliable, leak-resistant connection that supports high-flow intercooling systems and turbo upgrade plumbing.

This fitting is manufactured from 6061 aluminum and finished with a black anodize for corrosion resistance and long-term durability. The -12 ORB end uses a Viton™ O-Ring to provide a secure seal that resists fuel and coolant degradation while maintaining consistent performance in boosted applications.

• Material: 6061 aluminum — lightweight, corrosion-resistant construction for durable service life.
• Finish: Black anodized — improves surface hardness and protects against environmental wear.
• Sealing: -12 ORB end sealed with Viton™ O-Ring — chemical- and heat-resistant sealing for reliable leak prevention.
• Function: Adapts -12 ORB to -12AN — simplifies integration of air-to-water intercoolers and turbo upgrade plumbing into existing AN hose systems.
• Warranty: Includes Mishimoto Lifetime Warranty — backed by Mishimoto's reputation for motorsports-grade reliability.

Why this matters: the combination of CNC-grade 6061 aluminum and anodized finish provides structural stability for high-pressure, high-flow intercooling circuits, while the Viton™ O-Ring offers dependable sealing where coolant or charge air interfaces occur. This adapter is engineered to integrate with performance-focused setups where consistent sealing and corrosion resistance are required.

Applications include air-to-water intercooler connections and turbo upgrade plumbing where conversion between ORB and AN fittings is necessary. The compact form factor allows straightforward installation in tight engine bay locations common to motorsports and high-performance builds.
