Compatible Machines
When verifying fitment for Part 108845, ensure your machine uses the stainless-steel lower assembly Part 253597 (or equivalent) and has been converted via Kit 223443. Based on available documentation, the following machine family is compatible:
- Graco pumps built with Lower Part 253597 (Stainless Steel Lower) using Conversion Kit 223443 – e.g., heavy-duty displacement pumps in industrial finishing systems.
Note: Because explicit machine model names were not fully detailed in publicly available documentation for Part 108845, we strongly advise confirming your pump’s lower assembly number and conversion status in your machine’s manual or parts list before ordering.
Product Overview & Key Features
| Feature | Details |
|---|---|
| Material | UHMWPE (Ultra-High Molecular Weight Polyethylene) |
| Function | Vee-packing seal for dynamic rod/piston section in pump lower assembly |
| Typical Use | Used in Conversion Kit 223443 for Lower 253597 to upgrade pump packings to UHMWPE/PTFE configuration. |

Installation & Maintenance Tip
Before replacing the packings, relieve all fluid pressure and clean the fluid section thoroughly. During assembly, apply a light coating of compatible lubricant to the packings, seat them evenly and torque to the specification provided in the manual. The orientation of the vee-packing lips (facing down) is critical to prevent bypass and ensure pump seal integrity.
Frequently Asked Questions
- Check your pump lower assembly part number — the documentation lists Lower Part 253597 as compatible.
- Verify whether a Conversion Kit 223443 (to UHMWPE/PTFE packings) has been used or is required.
- Match the physical dimension and geometry of your pump rather than rely solely on machine model name.
