Note: Consult your AMERICAN representative for ratings in diameters not complimentary to our offered AMERICAN Earthquake Joint system sizes.
1.) Working pressure is the maximum pressure rating of the joint and is based on its capability to resist thrust due to internal pressure. If higher working pressure is required, contact AMERICAN.
2.) Laying length is nominal 20’. Where exact lengths are required, contact AMERICAN.
3.) Elongation % when fitting is used with a 20' nominal length of pipe.
