The GRINNELL G-PRESS Piping System requires only a press tool to complete the installation, and takes up far less space than traditional threaded, welded or flanged systems. Another bonus is its light weight. G-PRESS is up to 50% lighter when compared with traditional threaded piping systems. The absence of high heat and flames from welding torches is a major safety plus and, significantly, the reliability and dependability of G-PRESS is underpinned by its being tested and approved by major fire protection approval bodies. The new system can be used in hazardous areas, without any special precautions being necessary; installation does not generate hazardous fumes in the working area; and there is no possibility of foreign materials being introduced into the pipeline.
