The HTHP Pressure Relief Tool* (#170-91) provides a safe way to release the pressure in a clogged cell. It screws onto the HPHT cell cap using the existing valve stem port. Then, using a T-handle, the operator can drive a pin into the cell to puncture through any obstruction. The pressure will then vent safely through the vent pipe, away from people and equipment.


  • Easily punctures filter paper, cement screens, and ceramic disks
  • Safely directly vented pressure away from people and equipment
  • Conveniently fits the valve stem port on all standard HTHP or HPHT filter press cells
