Pressure breaker rings
Absorb pressure pulses at the front of the packing so the sealing rings behind them last longer.
- Position
- First rings in the packing case
- Materials
- Filled PTFE, PEEK
- Benefit
- Longer packing life
Overview
Pressure breaker rings sit at the cylinder end of the rod packing. They damp the pressure pulsation from each stroke so the rings behind them see a steadier load and wear more slowly.
We make them in stiff, creep-resistant filled PTFE and PEEK, matched to the packing set they protect.
