SAE J514, Straight Thread O-Ring Boss (ORB)

This straight thread connection uses the same threads as the JIC 37° shown above. However the 37° flare has been removed and an o-ring has been added. When mated with a female o-ring boss port the o-ring is trapped in a special tapered counter bore to affect the seal.
