Chesterton’s 14K Restriction Bushing is intended to be used as a barrier when using a flush in rotary applications. The 14K can also be used as a thermal barrier in boiler feed applications. In the absence of flush the 14K prevents abrasive materials from entering the stuffing box, acting much like a wiper on a cylinder.
- Available in split or solid to ensure easy installation.
- PTFE offers wide fluid compatibility.
- Acts as a check valve when flush is shut off.
- Custom engineered sizing to fit exact equipment dimensions.
- Cryogenic to 230°C (450°F).
- Tapered lip design controls fluid by-pass, increases flush efficiency, extends packing and seal life.
