AN Male to AN Male Adapters - Stainless Steel

Connect two compatible female AN connections with our AN Male to AN Male Adapters - Stainless Steel. This AN3 adapter combines a 3/8"-24 UNF convex male connection with a 3/8"-24 UNF concave male connection, providing different sealing geometries at either end while retaining the same AN3 thread size.

Why Choose Our Stainless Steel AN Male to AN Male Adapters?

AN3 Convex to Concave Connection

Combines an AN3 convex male connection with an AN3 concave male connection for joining compatible female fittings with different mating seat geometries.
3/8"-24 UNF Threads

Both connections use the AN3 3/8"-24 UNF thread, while the convex and concave seats provide the respective sealing surfaces.
303/304 Stainless Steel

Offers excellent strength and durability for demanding automotive and motorsport applications.
Natural Stainless Steel Finish

The corrosion-resistant natural finish requires no additional coating and provides a clean, durable appearance.
Precision CNC Machined in the UK

Manufactured in the United Kingdom for accurate thread form, sealing geometry and consistent fitment.

Check the Mating Seat as Well as the Thread

Both ends use the same AN3 3/8"-24 UNF thread, but the sealing geometries are different. One connection has a convex male seat and the other has a concave male seat, so check the mating connection at each end before ordering.

Frequently Asked Questions

What is an AN male to AN male adapter used for?
It allows two compatible female connections to be joined. This version has an AN3 convex male connection at one end and an AN3 concave male connection at the other.
What size are the connections?
Both connections use an AN3 3/8"-24 UNF thread.
Are both ends of the adapter the same?
No. Although both ends use the same AN3 3/8"-24 UNF thread, one has a convex male seat and the other has a concave male seat. The mating connection must have the correct corresponding sealing geometry.
Does the thread itself create the fluid seal?
No. The straight UNF threads retain the connections, while the mating seat surfaces provide the fluid seal.
Do these adapters require thread sealant?
No. Thread sealant should not be required on the straight AN3 UNF threads because the threads are not the fluid sealing surfaces.
What are the adapters made from?
They are precision CNC machined from 303/304 stainless steel for excellent strength and durability.
Where are these adapters manufactured?
They are precision CNC machined in the United Kingdom.
Are these adapters reusable?
Yes. They can be removed and reused provided the threads and sealing surfaces remain clean and undamaged.
