TITLE OF PAGE FLUID RESISTANCE CHART
®
The following information has been prepared as a guide to the fluid resistance of the ATRA-FLEX ® flexible coupling inserts. This table should be used as a guide only. Other requirements necessary for satisfactory performance must also be taken into consideration.
The best way to determine whether or not the insert will be entirely satisfactory for a given application is to test it in actual service. If this is impractical, then tests should be devised which simulate actual service conditions as closely as possible.
The inserts were immersed for seven days at 75°F. The rating was based on volume change according to the following key:
