The Gruvlok® Figure 7022 coupling with Gruv-Ring forms a flexible grooved end pipe joint for use on steel pipe. Services for this versatile connection include large O.D. mining applications such as process, tailings and slurries. The coupling’s multi-segment design supplies optimum strength for working pressures to 175 PSl.
