Adapt AN Connections to BSPP Ports

These adapters provide a direct transition between a female AN fitting and a compatible female BSPP port. The male AN connection uses a JIC 37° flare, while the male BSPP connection uses a parallel thread and seals against the mating port using the supplied O-ring.

JIC 37° AN Connection

The male AN connection seals against the corresponding JIC 37° flare inside a compatible female AN fitting.

Parallel-Thread BSPP Connection

The male BSPP connection uses a parallel thread and seals against a compatible mating port using the supplied O-ring.

BSPP and NPT Are Not Interchangeable

BSPP uses a parallel thread while NPT uses a tapered thread. Nominal pipe sizes can appear similar, but the thread forms and sealing arrangements are different. Confirm that the mating port is BSPP before ordering.

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 BSPP male adapters used for?
They provide a transition between a female AN fitting and a compatible female BSPP port.
How does the AN connection seal?
The male AN connection seals against the corresponding JIC 37° flare inside a compatible female AN fitting.
Is the BSPP thread parallel or tapered?
BSPP uses a parallel thread. It should be connected only to a compatible BSPP port with the correct sealing arrangement.
How does the BSPP connection seal?
The BSPP connection seals against the mating port using the supplied O-ring.
Is the O-ring included?
Yes. The O-ring required for the BSPP connection is supplied with the adapter.
Do these adapters require thread sealant or PTFE tape?
No. The AN connection seals on its JIC 37° flare and the BSPP connection seals using the supplied O-ring, so thread sealant or PTFE tape is not required.
Is BSPP the same as NPT?
No. BSPP uses a parallel pipe thread, while NPT uses a tapered pipe thread. They use different thread forms and sealing methods and should not be treated as interchangeable.
Are these adapters compatible with braided hose assemblies?
Yes. The AN end can connect to a compatible female AN hose fitting used on a braided hose assembly, while the BSPP end connects to a compatible BSPP port.
What are the adapters made from?
They are manufactured from 6061-T6 aluminium with a black anodised finish.
