Earl's Performance AT981604ERL Straight Male AN -4 to 1/8" NPT Adapter Fitting

The Earl's Performance AT981604ERL is a straight male adapter fitting that converts AN -4 (dash 4) connections to 1/8" NPT male threads. This precision-engineered fitting is manufactured from high-quality aluminum and features a hard anodized coating that penetrates deep into the aluminum substrate for superior wear and corrosion resistance.

Key Features:

• AN -4 male to 1/8" NPT male thread configuration
• Hard anodized aluminum construction for twice the lifespan of traditional anodized fittings
• Corrosion-resistant finish ideal for fuel, oil, and coolant applications
• Precision-machined threads ensure leak-free connections
• Aggressive black anodized appearance complements performance builds
• Made in the USA with strict quality control standards

Earl's hard anodized fittings are engineered for demanding automotive, racing, and custom plumbing applications where reliability and durability are essential. The advanced anodizing process creates a harder, more durable surface that resists thread galling and maintains seal integrity over repeated installations.
