Do these fit 12AN ORB fittings?

Yes. They are sized for 12AN ORB (O-ring boss) ports and adapters, which use a face-sealing O-ring.

Are the fittings included?

No. This is a set of five O-rings only. The 12AN fittings and adapters are sold separately.

Peterson Fluid lists them as rubber. Check compatibility with your fluid and temperature before use.

It seats in the chamfered boss face of the port or adapter, and the fitting's shoulder compresses it to seal.

It is best to replace O-rings whenever a fitting is loosened, since a compressed or nicked ring can leak.
