Earl's Performance Swivel-Seal 45-Degree AN Hose End Fittings

Earl's Performance Swivel-Seal® 45-Degree AN Hose End Fittings are the industry-standard choice for adjustable, reusable fluid line connections in racing and high-performance applications. Earl's invented the self-indexing hose end in 1972, and the Swivel-Seal® line has remained the most widely sold adjustable AN hose end on the market — a testament to its proven reliability across decades of motorsports and street performance use.

Key Features:

• 360° Swivel Adjustment After Installation: Stainless steel retention pins allow full rotational freedom once the hose end is assembled onto the hose, making final routing and clocking of every connection effortless without compromising the integrity of the seal
• Aerospace-Proven Nipple & Cutter Sealing System: The nipple-and-cutter primary seal design has served as the aerospace standard for high-pressure fluid connections for over five decades — a sharp outer cutter ring bites into the rubber hose liner to form a leak-proof, high-integrity seal
• 45-Degree Bent Tube Configuration: The angled geometry maximizes internal flow capacity while keeping plumbing routed cleanly around chassis components, firewalls, and tight engine bay obstacles
• Aerospace-Grade Aluminum Construction: Every hose end is machined from aluminum alloys that meet or exceed the minimum material requirements established for aerospace hose end specifications
• Precision Machined to Exacting Tolerances: Each component is precision machined for consistent, trouble-free performance and long service life in both competition and street use
• Compatible with Earl's Rubber-Lined Braid Hose: Designed for use with Earl's Perform-O-Flex™, Pro-Lite 350™, and Auto-Flex™ braid-protected hose lines
• Available in Multiple AN Sizes and Finish Options: This product line spans a broad range of AN hose sizes and anodized finish choices — select the variant that matches your build requirements

Whether plumbing fuel, oil, coolant, or other critical fluid systems, the Swivel-Seal® 45-Degree Hose End eliminates the frustration of fixed-position fittings. The 45-degree geometry is purpose-built for routing lines around chassis members and firewall transitions, while the swivel function lets you dial in the precise clocking of every connection after final assembly. Trusted by professional race teams and performance builders worldwide, Earl's Swivel-Seal® hose ends are a genuine original — engineered to the same aerospace-influenced standards that have defined the product line since its introduction.
