What is an ORB fitting?

ORB stands for O-Ring Boss. These fittings use a straight-cut thread and rely on an O-ring to create a seal, which is often more reliable than traditional pipe threads. This adapter has a male ORB end that fits into a female ORB port.

What is the difference between AN and ORB fittings?

AN fittings use a flare to seal, while ORB fittings use a straight thread with an O-ring. This adapter allows you to connect a hose with an AN fitting to a component that requires an ORB fitting.

What does the -20 and -16 refer to?

The numbers refer to the size of the fitting in 16ths of an inch. So, -20AN means the flare end is sized for a hose approximately 20/16ths of an inch in diameter, and -16 ORB refers to the straight thread port size.

About this part

Product Details

This Vibrant Performance adapter fitting is designed to connect a -20AN size hose with a flare fitting to a component that uses a -16 ORB (O-Ring Boss) straight thread. It's a common piece for custom fuel systems, oil lines, or other fluid transfer setups where you need to adapt between different fitting types. The fitting itself has a -20 Male AN flare on one end and a -16 Male ORB straight thread on the other.

It's made from 6061 aluminum alloy, which keeps the weight down, and it's finished with a black anodized coating for durability and a clean look. This adapter includes an O-ring seal to ensure a leak-free connection when installed into a compatible ORB port. These fittings are generally used with popular oil pumps, fuel pumps, and fuel filters, making them a versatile choice for many custom builds.
