The 1/2" NPT to -8 AN fitting is designed to convert 1/2" NPT female ports to -8 AN fuel line connections in high performance fuel systems.

Whether you're plumbing a fuel shutoff valve, pump, regulator, or filter, this adapter allows you to transition from tapered pipe thread to 37° AN flare connections with confidence.

Tech Insight

When installing NPT to AN adapters:

Apply thread sealant to the NPT side only.

Never apply sealant to the AN flare surface.

Do not over-tighten — NPT threads seal via taper interference.

Upgrading to -8 AN plumbing is common in boosted LS builds, high-horsepower race applications, and off-road rigs where consistent fuel volume under load is critical.
