The GRACO 123989 is a tee fitting designed to connect tubing with a 1/2 inch outer diameter to a 3/4 inch NPT (National Pipe Thread) port. It is typically constructed from durable materials such as brass or steel, intended for use in fluid and air systems to facilitate the splitting or merging of flow paths within GRACO equipment. This fitting is commonly used in lubrication, pneumatic, and hydraulic systems for reliable and secure connections.

Key Features:
