Grinnell announces the release of its G-PRESS copper fittings, which include an innovative feature that helps ensure a leak-tight seal. The Grinnell G-PRESS copper system provides a complete line of mechanically joined press fittings for sizes 1/2-in. through 2-in. copper tube. The fittings work with hard, half-hard and soft copper tubes. To help ensure a leak-free system, the fittings have a Leak-Before-Press feature molded into the O-ring in two positions, which allows the installer to identify fittings that have not been properly pressed during the system test.
