Steel Straight Thread O-Ring Boss (SAE/ORB) 

Our steel SAE straight thread o-ring boss (ORB) come in many configurations such as 6400 straight thread connector, 6801 90° straight thread elbow, and many more. This straight thread connection uses the same threads as the 37° JIC. 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.
