Frequently Asked Questions

Over time, internal seals of the dryer can degrade, leading to leaks or moisture bypass. This kit restores those seals, helping your dryer perform reliably.

First, relieve system pressure completely. Then disassemble the desiccant housing, remove the old components, clean surfaces, insert the new seals and rings from the kit, and reassemble following proper torque specs.

It’s recommended during routine maintenance or whenever you replace or regenerate the desiccant. Inspect your sight‑glass and seals regularly to decide when the repair kit is needed.

While third-party parts may be cheaper, using the genuine Graco 15C064 kit ensures correct fit, pressure resistance, and long-term reliability per Graco’s design.
