Industrial 1-1/2NPT-ORB-4BOLT-FLANGE-ADAPTER is a flange-style connector that joins a 1-1/2-inch NPT threaded line to a 1-1/2-inch O-Ring Boss (ORB) four-bolt flange. One end accepts 1-1/2" NPT male threads, while the opposite end provides a 1-1/2" ORB flange with four bolts for a compatible flange-to-flange connection. Use this adapter to link components with an ORB 4-bolt interface to piping in industrial fluid systems.
