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

This straight thread connection uses the same threads as the JIC 37° . 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.
