Frequently Asked Questions

It services the throat packing section of 145cc lower pumps, sealing around the displacement rod.

No. This is a throat packing kit only. Piston packing kits are sold separately.

PTFE provides chemical resistance and low friction, helping extend seal life and maintain smooth rod movement.

Confirm your lower pump displacement is 145cc and check the kit number in your Graco parts manual before purchase.
