• Rubber Chunking / Splitting - The most common failure mode. Chunking can result from mechanical stress and strain, fluid incompatibility leading to material breakdown, uneven growth (internal heat build-up) or abnormal shrinking.  Rubber curing (hardening) will also accelerate this failure method. Curing is accelerated greatly with heat and can even be introduced prematurely during the rubber injection process itself.

 

• Blistering - Seen as a reaction to certain lubricants and gases resulting in what known as explosive decompression.

 

• De-bonding - Primers / Glue reacting to fluid and lubricants incompatibility or poor application. 

 

• Seal (Performance) / Pressure Issues - Poor fit from one or more of the above conditions.
