Installation & Service Advice
Proper installation of the 15A057 packing is essential to ensuring optimal performance and service life of your pump’s fluid section.
Clean the stuffing box and fluid chamber thoroughly before inserting the new packing.
Check the shaft or rod surface for scoring or damage — repair or replace as needed.
Install the PTFE vee rings with correct orientation and even compression to avoid leaks or premature wear.
Follow manufacturer-recommended torque and assembly sequence to avoid misalignment or seal extrusion.
After reassembly, run the pump under low-load conditions to check for proper sealing and stability before full operation.
When Replacement Is Needed
Emerging fluid leaks around the packing or rod interface
Visible wear, deformation or glazing of previous packing material
Reduced pump performance, inconsistent output or increasing maintenance intervals
Abrasive or chemical damage to the sealing area requiring upgrade to OE part

Frequently Asked Questions
It provides a high-performance seal around the rod or shaft in a fluid pump’s stuffing box, preventing leaks and maintaining pressure integrity.
While possible, it’s not recommended — new PTFE packings ensure seal integrity, correct fit, and longevity; reusing worn elements may lead to leaks or premature failure.
Replace it during major pump rebuilds, or if you observe leaks, increased maintenance frequency, or diminished fluid performance.
No — you should verify that your pump’s parts list specifies part number 15A057 before purchasing.
