Material and finish you can rely on

Constructed from a durable 6061-T6 aluminum alloy, the adapter is designed to withstand vibration and temperature swings common in automotive and industrial environments. The black finish adds a restrained, professional look while helping resist surface wear and corrosion over time.

Real-world uses and benefits

This swivel fitting is well suited for applications such as connecting fuel supply lines, feeding regulators, or integrating into vacuum reservoirs where routing flexibility matters. The 90-degree swivel reduces bend radius and hose strain, potentially helping maintain consistent flow and reducing install fatigue in tight spaces.

• Flexible routing: 90° swivel helps navigate confined layouts without sharp bends.
• Secure seals: Dual seal angles support reliable connections when paired with appropriate sealants.
• Broad compatibility: Works with common 6AN flare lines and 3/8-18 NPT ports for versatile builds.
• Durable and lightweight: Aluminum construction keeps weight down while withstanding demanding environments.

Whether you’re assembling a high-performance fuel line, setting up a regulator feed, or linking vacuum components, this adapter offers a practical, non-restrictive option that may help you achieve cleaner layouts and dependable connections. As with any high-pressure fluid system, plan your routing thoughtfully and use the recommended sealant practices during installation.
