- What does this fitting adapt?
- It takes a 6AN ORB (O-ring boss) port and gives you a 5/16-inch hose barb. The ORB side seals with an O-ring against the port face.
- Will it fit my Radium fuel rail or regulator?
- It fits Radium parts that use a 6AN ORB port, which covers many fuel rails, surge tanks and fuel pressure regulators. Check your part's port size first, since some Radium ports are 8AN ORB.
- Can I use it with braided hose?
- The barb is sized for 5/16-inch push-on hose, typically rubber or soft line held with a clamp. For high-pressure braided line, use a proper AN hose end instead.
- Is an O-ring included?
- The fitting is the adapter itself; confirm whether an O-ring comes with it. ORB ports need a fuel-compatible O-ring to seal.
- What thread is the ORB side?
- It is a 6AN ORB port, which is a straight thread with an O-ring seal, not a tapered pipe thread. Do not substitute NPT.
