a. Maximum available gap between pipe ends. Minimum
b. Maximum pressure is based on standard weight steel
pipe. Pressure ratings may differ on other pipe materials and/or wall thickness. Contact GRINNELL Mechanical Products for details.
c. Max End Gap and Deflection are for cut grooved standard weight pipe. Values for roll grooved pipe are reduced by 50%.
