Frequently Asked Questions
This grommet is listed specifically for the Reactor 2 E-30 and E-XP2 series. While it may physically fit older models, compatibility isn’t guaranteed — you should verify your machine’s parts manual to confirm correct part number and seal type.
Replacement frequency depends on usage, material sprayed, and environmental conditions. Inspect the seal periodically for wear or deformities — replace if you notice leaks, stiffening, or damage to maintain system integrity.
While non-OEM options may fit, using a genuine Graco grommet ensures correct material compatibility, fitment and seal performance. If you choose an aftermarket option, verify that the durometer, dimensions and chemical resistance match the original.
Summary
The GRACO 120685 grommet is a compact but critical sealing part for select Graco proportioner systems — notably the Reactor 2 E-30 and E-XP2 series. Proper fitment and periodic inspection help ensure reliable performance and maintain fluid-system integrity.
Always double-check your machine’s parts breakdown or consult your Graco distributor with your model and serial number to confirm compatibility before ordering.
