Nitrous Outlet AN ORB to AN cutter forged hose ends are high performance fittings for a nitrous system that connect a hose with a synthetic rubber liner to a component with an ORB (Oil/Fluid Pressure) port. The "Cutter" design features a nipple that cuts into the hose's liner to provide an exceptionally strong clamping force, while the "Forged" aspect indicates high-strength construction. These aluminum fittings have a protective black coating—and are available in a variety of angles, AN hose end and adapter sizes. Here's a breakdown of the components: * AN: Refers to the Army-Navy standard fitting size, which is a common type of fitting for fluid and fuel lines in high-performance applications. * ORB: Stands for Oil/Fluid Pressure (or sometimes O-Ring Boss), a fitting type that uses an O-ring to create a leak-free seal with a port on a component. * Cutter: This refers to the specific type of hose end. It has a "cutting nipple" that bites into the synthetic rubber inner liner of the hose, creating a more secure connection than a standard hose end. * Forged: This indicates the construction method, meaning the fitting is made by shaping heated metal through hammering or pressing, resulting in a very strong and durable component. * Hose Ends: These are the fittings that attach to the end of the hose, providing the connection to the vehicle's components.
