AVA45 TY254 Pressure Breaker Special Packing Ring

The AAVOLYN Type 254 is designed to be installed in the first sealing groove toward the cylinder. It’s internal grooving arrangement is used to trap solids in the gas, preventing them from filling the packing groove and restricting the performance of the packing rings. This design has been used in many applications where packing rings have not been able to function effectively due to the build up of solids in the groove from the cylinder. By minimizing the amount of solids allowed to enter the sealing ring area, the life of the packing assembly is increased.
