The GRACO 155470 is a swivel union fitting designed to connect fluid lines at a 90-degree angle. It features a 1/2-inch NPT (National Pipe Thread) male end and a 1/2-inch NPSM (National Pipe Straight Mechanical) female end, allowing for flexible and secure connections in fluid transfer systems. The material is not specified, but such fittings are typically made from durable metals for industrial use. Its primary function is to facilitate reliable, leak-free connections in GRACO equipment, particularly in spray foam, lubrication, and fluid handling systems.
