Frequently Asked Questions

Over time, internal seals in the dryer housing degrade. Replacing them with the 15C066 kit restores airtight sealing and ensures the desiccant works effectively.

First, fully relieve system pressure. Disassemble the desiccant housing, remove old seals, clean all contact surfaces, insert the new components from the kit, and reassemble securely.

It’s recommended to use the kit during routine maintenance or whenever you open the dryer housing. Rebuild intervals may vary depending on usage and contamination.

Aftermarket kits may be available, but using the genuine Graco 15C066 ensures the correct materials, sealing performance, and pressure tolerance as originally designed.
