Overview of the Graco 109304 V-Packing

The 109304 V-Packing (PTFE) is a genuine Graco sealing component designed for use in displacement pump assemblies. This part functions as a throat packing (i.e., sealing the displacement rod area) and is made of high-quality PTFE material, offering excellent chemical resistance and durability.

Key Features

Material: **PTFE** (Polytetrafluoroethylene) for superior sealing life.
Application: The throat packing in a displacement pump stack.
Installation orientation: For the throat packings, the lips face down.

Compatible Machines

The following pump and equipment models are known to use part number 109304 in their packing stack. Always verify the displacement pump model and series before ordering.

Displacement Pump: **236897, Series A** (when fitted with Packing Kit 237173)

Note: While documentation specifically lists pump model 236897 with Kit 237173, this packing may also apply to other Graco displacement pump variants using PTFE throat packings. Confirm by checking your pump’s parts list or manual.

Installation Notes & Maintenance

Step	Detail
1. Depressurize	Before disassembly, relieve air and fluid pressure per pump manual.
2. Packing orientation	Install throat V-packing with lips face down; piston packings (if replacing) face up.
3. Lubrication	Lightly coat packing and gland surfaces with compatible lubricant to ease break-in.
4. Re-assemble and test	Re-assemble pump, restore pressure slowly and observe for bypass or leakage.
5. Replacement interval	Replace when you observe creeping pressure, fluid bypass at the wet-cup, or loss of pump prime.

Why Choose the 109304 V-Packing?

Choosing the 109304 V-Packing ensures you are using a genuine Graco PTFE sealing component, which offers:

Better chemical resistance compared to leather or UHMWPE packings.
Reduced downtime with improved seal life in demanding environments.
Correct geometry and materials specified for Graco displacement pumps.

Frequently Asked Questions

A V-packing (or V-ring) is a sealing element with a “V” profile which when compressed forms a tight seal around the rod or shaft while allowing axial movement. In this case, the 109304 is used around the displacement rod in a Graco pump.

While it isn't always required, it is often good practice to inspect both stacks during maintenance. If one stack shows wear or leakage signs, replacing both may reduce future downtime.

Yes — certain Graco displacement pumps permit different packing materials (leather, UHMWPE, PTFE) via optional kits. For example, Kit 237174 covers UHMWPE and leather packings. However, for PTFE-only profiles, use 109304 to match the PTFE stack.
