PMC Motorsport Straight AN to Thread Adapters (NPT, ORB, Metric) focuses on PMC aluminium straight AN-10 flare to metric transitions, used when you need to connect an existing M20x1.5, M22x1.5 or M24x1.5 port to AN plumbing. These are straight male–male union adapters commonly used in fuel and oil system builds where service access matters.

PMC Motorsport Straight AN to Thread Adapters (NPT, ORB, Metric) – AN10 to metric unions for clean routing, repeatable sealing and easy servicing
This page groups PMC straight adapters built to bridge AN-10 flare connections with metric threaded ports. The current selection covers three straight male–male union solutions on the metric side: M20x1.5, M22x1.5 and M24x1.5.
In practice, these parts are useful when you want to standardise a fuel or oil plumbing setup around AN hose ends, while the component you are connecting to is still on a metric interface. The benefit is consistency: tidy routing, predictable servicing, and fewer “mystery threads” when you revisit the car later.
Technical Basics
On the AN-10 side, sealing is typically achieved at the flare seat rather than on the thread. That is why seat condition and cleanliness matter more than adding thread sealant on the AN side.
On the metric side, thread accuracy is critical: the options here are M20x1.5, M22x1.5 and M24x1.5. One short warning: do not mix near-matches with a different pitch, because it can damage the port and create slow leaks that are hard to trace.
A straight union adapter works best when you treat each interface correctly: flare-seat sealing for AN, and correct thread engagement plus the component’s intended sealing face on the metric port. If the receiving port’s sealing method is unclear, follow the component manufacturer’s spec rather than guessing.
Selection Criteria
Start by identifying the receiving port thread: M20x1.5, M22x1.5 or M24x1.5. Next, confirm the rest of your line is truly AN-10 end-to-end (hose ends, fittings, and any intermediate adapters).
Consider packaging: a straight adapter shifts the line in one axis, so check tool access for tightening and ensure the hose does not side-load the joint. In fuel and oil systems, avoiding side-load and vibration stress is just as important as picking the right thread.
If your build also includes other standards (such as NPT, ORB or different metric ports), it is often easier to plan everything from the master category. Use Straight AN to Thread Adapters (NPT, ORB, Metric) to align sizes and interfaces across the whole system.
Installation & Maintenance
Clean threads and sealing faces before assembly, and start the metric thread by hand to prevent cross-threading. On the AN-10 side, protect the flare seat from nicks because that is where the seal is made.
After installation, leak-check under operating pressure and temperature. If the system is serviced frequently, keeping sealing faces pristine and assembling cleanly is more reliable than repeated “tighten a bit more”.
FAQ
What are AN10 to M20/M22/M24x1.5 adapters used for?
They let you connect a metric threaded port to AN-10 plumbing. The items on this page are straight male–male union adapters. Always match the exact metric thread and confirm the receiving component’s sealing design.
Do I need thread sealant on the AN side?
Usually not, because AN typically seals at the flare seat rather than the thread. Leaks are more often caused by a damaged or dirty seat than by a lack of sealant. Keep the seat clean and use compatible mating fittings.
How can I be sure it’s M22x1.5 and not another M22 pitch?
Pitch is the key detail, so verify it from the component specification or existing part markings. Forcing a near-match can damage threads. If you are unsure, confirm with the component documentation before ordering.
Can I use these in fuel and oil systems?
Yes, this type of adapter is commonly used to standardise plumbing in fuel and oil builds. Final suitability depends on your full setup (fluid, temperature, and how the receiving port seals). Always pressure-test after installation.
What does “male–male union” mean here?
It means both ends are male interfaces, acting as a straight joiner between AN-10 flare and a metric thread such as M24x1.5. Allow enough clearance for spanners and avoid side-load from hose routing. Match the exact threads on both sides.
Filter to the correct thread size, confirm the sealing interface on the product page, and order the PMC adapter that fits your port.
