Maximum available gap between pipe ends. Minimum Gap = 0
Maximum Pressure and End Load are total from all loads based on standard weight steel pipe. Pressure ratings and end loads may differ for other pipe materials and/or wall thickness. Contact GRINNELL Mechanical Products for details.
Maximum End Gap is for cut grooved standard weight pipe.
