Cherne Urethane pillow plugs, Well Monitor plug and the Petro Econ-O-Grip can be used with most hydrocarbons. Contact Cherne engineering for specific applications.

All of Cherne’s pneumatic pipe plugs are made from natural rubber. The only exception is our yellow pillow plugs which are made from a polyurethane impregnated fabric. 

Inflation pressure should be checked a minimum of once every 4 hours while a pneumatic plug is in use.

This answer depends on how the plug is maintained. If the instructions are followed in the Cherne Safety Instruction Manual, it is not unusual for the plug to last for many years. If the instructions are not followed, a plug can be destroyed during the first use. Cherne pneumatic plugs come with a 2 year warranty from date of manufacture.
