Frequently Asked Questions

It installs in the throat/rod packing stack of the displacement pump. Its “V” profile energizes under pressure to seal around the moving rod.

Increased fluid seepage at the throat, difficulty maintaining pressure, or visible wear/flat spots on the packing during service are common indicators.

Install in the correct orientation (opening of the “V” toward the pressure side unless the service manual states otherwise). Lightly lubricate with a compatible grease and follow the official torque and stack order in the model-specific manual.

No. This is a PTFE element and may be used alongside other materials depending on the stack design. Always match the packing materials and order specified for your exact pump model.
