380 Series — AN Flare to NPT Steel Adapters

The Speedflow 380 series provides a comprehensive range of AN male to NPT adapters in steel construction, built to handle the pressures and temperatures of demanding performance and motorsport environments. The SF382-03 is the -3 AN variant in this series, offering a compact, lightweight solution for lower-flow applications such as brake lines, clutch hydraulics, and gauge connections. For higher-flow applications requiring -4 AN, see our SF380-04 listing.

AN to NPT — Installation Note

NPT fittings use a tapered thread that seals via thread interference. Always apply appropriate thread sealant or PTFE tape to the NPT threads during installation to ensure a leak-free seal. Do not overtighten — NPT threads can crack cast components if over-torqued.

Sold individually. Weight: 16g. Compatible with standard -3 AN fittings and 1/8" NPT ports.
