Buying Guide: 6AN 180 Degree Fittings
Key considerations help ensure you select fittings that fit your hoses and system requirements.
- Material durability: Aluminum 6061-T6 offers light weight and corrosion resistance; consider stainless steel for extremely corrosive environments.
- Hose compatibility: Some fittings are designed specifically for CPE nylon braided hoses, others for PTFE lines or rubber hoses. Verify your hose type before buying.
- Thread size and seal angle: Most 6AN fittings use 9/16-18 UNF threads and seal with a 37-degree flare. Confirm your barb or end connections align with the intended seal.
- Angle and swivel: A true 180-degree elbow reduces hose bending stress. Swivel designs help with installation in tight spaces.
- Pressure and temperature ratings: Common ratings approach 1,500 PSI and temperatures from -65°F to 252°F. Check if these align with your system’s operating range.
- Installation considerations: Some fittings are easier to install with an adjustable wrench or may require specific hose clamps for secure seating.
