Overview & Key Details
The Graco 104319 Packing O-Ring is a precision PTFE (Teflon) sealing ring used in the pressure control/transducer area of many Graco airless paint sprayers. Its PTFE construction offers excellent chemical resistance and long service life compared with standard rubber O-rings. Use it to restore a tight seal around the pressure transducer or related control components and eliminate leaks or pressure instability.
Compatible Machines
- Graco Ultra Max 695 (transducer/pressure control seal)
- Graco Ultimate MX 695 (transducer/pressure control seal)
- Other Graco airless sprayers that specify O-ring 104319 for the pressure transducer or control module (confirm in your model’s parts manual)
Compatibility note: Model coverage depends on the pressure control/transducer design. If your sprayer’s parts list calls out 104319, this O-ring fits.

- Exact-fit Graco part for transducer/pressure control sealing
- PTFE material for durability, solvent resistance, and stable sealing

Frequently Asked Questions
No. 104319 is a PTFE O-ring. It is stiffer than rubber and chosen for chemical resistance and long life in the pressure control/transducer area.
Check your sprayer’s parts manual for the pressure control/transducer assembly. If it lists O-ring 104319, this is the correct seal.
Lightly clean and inspect the groove and mating surfaces. Seat the O-ring without twisting; do not overstretch. Reassemble evenly to avoid pinching.
Fluid seepage at the pressure control, erratic pressure readings, or difficulty maintaining set pressure are common signs the 104319 needs replacement.
Generally, no sealant is required; the PTFE O-ring provides the seal when properly seated. Use only what the Graco service manual specifies for your model.
