Adapt AN Connections to NPT Male Ports

These adapters provide a direct transition between a female AN fitting and a compatible female NPT port. The AN connection uses a JIC 37° flare, while the NPT connection uses a tapered male pipe thread.

AN Male Connection

The AN side uses a male JIC 37° cone flare and seals against the corresponding flare inside a compatible female AN fitting. Thread sealant is not required on the AN connection.

NPT Male Connection

The male NPT connection uses a tapered thread for installation into a compatible female NPT port. Use suitable PTFE tape or thread sealant, keeping tape clear of the first thread and fluid opening.

6061-T6 Aluminium Construction

The adapters are manufactured from 6061-T6 aluminium with a black anodised finish.

Frequently Asked Questions

What are AN male to NPT male adapters used for?
They provide a transition between a female AN fitting and a compatible female NPT port.
How does the AN connection seal?
The male AN connection uses a JIC 37° cone flare and seals against the corresponding flare inside a compatible female AN fitting. Thread sealant is not required on the AN connection.
How does the NPT connection seal?
The NPT connection uses a tapered thread. Use suitable PTFE tape or thread sealant appropriate for the application.
How should PTFE tape be applied to the NPT thread?
Apply PTFE tape to the male NPT thread while keeping it clear of the first thread and fluid opening.
Is NPT the same as BSPP?
No. NPT uses a tapered thread, while BSPP uses a parallel thread and a different sealing arrangement. They should not be treated as interchangeable based on nominal size alone.
