Frequently Asked Questions

It replaces the PTFE throat packings in compatible 250cc lower pumps, restoring rod sealing and preventing leakage.

No. This kit is for the throat packing section only. Piston packing kits are separate.

PTFE provides chemical resistance and low friction, which extends seal life and ensures smooth rod movement in high-capacity pumps.

Verify your pump lower displacement is 250cc and check the kit number in your Graco parts manual before purchase.
