Buying Guide

Match AN size to your hose

Confirm the AN size (e.g., 6AN, 12AN, 16AN, 20AN) of both hose and port to ensure a leak-free, proper fit and avoid adapters that require excessive modifications

Choose the right swivel vs. fixed end

Swivel fittings ease installation and reduce hose twist in tight spaces, while fixed ends can be simpler and lighter for static routing

Consider material and corrosion resistance

Aluminum 6061-T6 fittings are lightweight and common for fuel and PTFE lines; verify finish/coating and compatibility with your fluid to prevent corrosion or contamination

Check compatibility with hose type

Ensure fittings are specified for your hose construction—PTFE-lined, CPE braided, or other—since internal sealing and clamping differ by hose type

Look at angle and routing needs

45° or other angled hose ends help with tight routing and reduce stress on connections; pick angles that match your installation geometry
