The GRINNELL G-FIRE Figure 707
Grooved Heavy-Duty Flexible Couplings, when properly installed, provide a dependable method of joining pipe, allowing for angular and linear deflection, thermal expansion and contraction, and misalignments of the pipe.
Figure 707 couplings are rated at pressures up to 500 psi (34,5 bar) depending on pipe size and wall thickness when used in fire protection service applications.
