WARNING MOST STANDARD CHERNE PNEUMATIC PLUGS
ARE DESIGNED TO HOLD AIR OR WATER BACK PRESSURE ONLY
AND MUST ONLY BE USED WITHIN THE DESIGNATED TEMPERATURE
RANGE! Use with other media or at temperatures outside of designated
range may cause the plug to fail. PLUG FAILURE MAY RESULT IN
DEATH, SERIOUS BODILY INJURY AND/OR PROPERTY DAMAGE!
3. DETERMINE THE USAGE TEMPERATURE AND THE
MEDIA THE PLUG MUST WITHHOLD.
TEMPERATURE RATING. Most standard Cherne natural rubber pneumatic
plugs are designed for use at temperatures from 0 to +125 DEGREES F.
(-18 to +52 DEGREES C.). Using a plug at a temperature below this
minimum may cause the plug to stiffen, resulting in incomplete pipe
contact, and the plug may dislodge when back pressure is applied. Usage
at temperatures above this maximum may damage the plug body and the
plug may rupture during ination and/or use. If the application requires
temperatures outside of these limits, call Cherne toll free at 1-800-843-
7584 for recommendations.
USE OF PLUGS WITH CHEMICALS.
If a plug is to be used in
chemical environments, call Cherne toll free at 1-800-843-7584 for
recommendations.
