Installation & Usage Notes
When installing the Graco 109256 V‑Packing, please observe the following:
- Ensure the machine model matches one of the compatibles listed above.
- Follow the pump manufacturer’s instructions for disassembly & reassembly of the throat housing or packing gland.
- Inspect the pump bore and packing gland for wear or damage before inserting the new packing—any irregular surfaces may shorten packing life.
- Lubricate the packing lightly if recommended by the manufacturer, before final assembly.
- After installation, operate the pump at low pressure to check for leakage, then gradually bring to full operating pressure.
Why Choose This Packing?
The Graco 109256 V‑Packing is designed with **UHMWPE**, which offers exceptional wear resistance, low friction and high abrasion tolerance compared to standard materials. Ideal for demanding high‑pressure spray and fluid handling systems where long seal life and minimal leakage are critical.
Frequently Asked Questions
To ensure compatibility, check your machine’s model number. If it matches one of the models listed above (for example 236612, 236611, 198469 or 236478) then the part is suited. Also verify in your machine’s service manual that part number 109256 is specified as the V‑packing for the throat housing.
The packing is made from UHMWPE, which offers excellent abrasion resistance and low friction. That means longer life and better sealing under high pressures, compared to standard packings. This is particularly important in aggressive fluid or high‑cycle pump applications.
While it’s possible the packing may fit other models, only the models listed under “Compatible Machines” are officially identified. Using it in other machines without confirmation may risk improper fit or performance. Always cross‑check the part number in your machine’s parts list.
If you observe leakage after installation, shut down the pump and relieve pressure first. Inspect the gland for correct tightening, verify the packing stack and orientation, and check the bore for wear or damage. Replace any worn components before reinstalling the packing.
