Fittings & Hoses

Connecting the System: High-Performance Fittings & Hoses for Pontiacs at Butler Performance

The AN Standard: The Professional's Choice

The vast majority of performance fluid systems rely on AN-style fittings, and Butler Performance stocks a wide array of these components from industry leaders like Russell and others.

• Thread Reliability: AN fittings use a 37-degree flared seating surface and straight threads, which, when properly assembled, create a reliable mechanical seal that is superior to standard pipe thread in performance applications.

• Material and Durability: Fittings are typically machined from lightweight aluminum or stainless steel, offering exceptional resistance to corrosion and high pressure. They are available in various finishes, including black anodized and silver (nickel-plated).

Featured Product Categories

Butler Performance offers components categorized into three key areas, covering all aspects of fluid routing:

1. Fittings

This category encompasses every connector needed to route fluids safely:

• Adapters and Unions: Straight, $45^\circ$, $90^\circ$, and $180^\circ$ elbow fittings in various AN sizes (e.g., -6 AN, -8 AN, -10 AN) are available for tight clearances and precise routing.

• O-Ring Boss (ORB) Fittings: Specialized fittings for modern components like high-flow fuel pumps and regulators that use a superior O-ring seal to prevent leakage.

• Block Adaptors: Fittings that screw into the engine block or oil pan to allow an AN line to be attached, simplifying custom oil cooler lines, vacuum connections, or oil pressure sensor setups.

2. Hose Kits & Accessories

These pre-assembled or bulk kits provide the materials needed to create custom lines:

• Braided Stainless Steel Hose: This is the standard for high-performance use. The inner synthetic or PTFE (Teflon) liner is protected by a tough outer layer of stainless steel braid, offering maximum abrasion resistance and pressure containment for fuel, oil, and vacuum lines.

• Nylon Braided Hose: A modern alternative that offers similar pressure handling but is significantly lighter and often less abrasive to surrounding parts and paint finishes. It’s a popular choice for street applications where weight is a factor.

• Hose Ends: Specialized, reusable hose ends are required to secure the hose to the fittings. Butler stocks both standard crimp-style and reusable compression-style ends.

3. Hoses

This includes bulk hose and specific pre-made lines:

• Pre-Assembled Lines: For common applications like oil pressure gauges, fuel pump connections, or specific brake lines, pre-made hose assemblies save time and ensure correct length and crimping.

• Specific Fluid Compatibility: Hoses are clearly labeled for compatibility, ensuring that high-pressure fuel (especially Ethanol/E85) or hot engine oil is routed through the correct hose type (e.g., specialized PTFE-lined hose for E85).

Integration with Other Systems

The Fittings & Hoses section is essential for completing the installation of other Butler Performance parts:

• Fuel Delivery: Crucial for connecting high-pressure EFI fuel pumps and regulators to the engine.

• Oil Systems: Used extensively for building oil cooler lines or adding remote oil filters.

• Vacuum and Pressure: AN lines and fittings are often used for reliable vacuum connections to accessories like brake boosters or boost lines for supercharged engines.

By offering a comprehensive array of AN-style fittings, hose materials, and installation accessories, Butler Performance gives Pontiac builders the ability to create secure, professional, and performance-ready fluid systems that will withstand the demands of any high-horsepower application.
