Aavolyn # 01-25142-017, Bronze TY251 Pressure Breaker Packing Ring


The pressure breaker is used to stabilize the packing in the compressor. It is bored slightly over the rod diameter to allow a controlled leakage at the bore of the ring. This breaking down of the pressure in the first packing cup allows a slow buildup and drop off of pressure on each stroke.
