Earl's Performance Vapor Guard Barb To NPT Adapter Fittings

Earl's Performance Vapor Guard Barb to NPT Adapter Fittings are purpose-engineered connection solutions that seamlessly integrate Earl's Vapor Guard hose into standard NPT-threaded fuel system plumbing. These adapters bridge the Vapor Guard barbed hose system to NPT-threaded ports commonly found on carburetors, fuel pumps, fuel pressure gauges, and other fuel system components — delivering a leak-free, corrosion-resistant connection that conventional fittings cannot match.

Built for Modern Fuels

Today's fuel blends are highly aggressive toward traditional rubber hoses and standard fittings. Many EPA-approved fuel blends contain additives that break down conventional rubber fuel lines from the inside, leading to dangerous leaks, fuel vapor permeation, and contamination of injectors and carburetor passages. Earl's Vapor Guard Barb to NPT Adapter Fittings are engineered to resist this chemical assault across all popular fuel types, including leaded and unleaded gasoline, diesel, biodiesel, E85, methanol, ethanol, and gasohol.

Key Features:

• Vapor Guard Retention Bead — A specially designed smooth retention bead retains the Vapor Guard hose securely under pressure while protecting the hose's critical inner liner from damage
• Multi-Fuel Compatible — Approved for use with leaded and unleaded gasoline, diesel, biodiesel, E85, 100% methanol, ethanol, and gasohol
• Black Brite-Dip Anodized Aluminum Construction — Precision-machined aluminum with a black anodized finish delivers long-lasting corrosion resistance, even when exposed to today's harsh modern fuels
• NPT Threaded Port Compatibility — Connects directly to standard NPT-threaded fuel system components including fuel pressure gauges, carburetors, fuel pumps, and accessory ports
• Tool-Free Assembly — Simply cut the hose, push it onto the barb, and secure with a hose clamp — no special tools required
• Part of the Complete Vapor Guard System — Engineered to work with Earl's Vapor Guard hose and matching stainless steel clamps for a fully integrated, permeation-resistant fuel system

Available in multiple configurations to suit a variety of fuel system layouts, these Vapor Guard Barb to NPT Adapters are an ideal solution for both carburetor and EFI builds running any modern fuel type. Single and dual ear crimp-style and screw-style stainless steel hose clamps are also available separately for a complete, secure assembly.
