Frequently Asked Questions

It replaces the PTFE throat packings in compatible 290cc lower pumps, restoring rod sealing and preventing leakage.

No. This kit is specifically for the throat packing section only. Piston packing kits are sold separately.

PTFE provides chemical resistance and low friction, extending seal life and ensuring smooth rod operation in high-capacity pumps.

Confirm your lower pump displacement is 290cc and check the kit number in your Graco parts manual before purchase.
