Marsh RP40407 Moistening Brush for TDH and TDE Dispensers
The Marsh RP40407 Moistening Brush is a replacement part used to apply water to water activated gummed tape during the dispensing process. Proper brush condition helps support even water coverage across the tape adhesive surface before application to the carton.
If tape is not sticking correctly, the moistening brush should be cleaned and tested first. If the tape shows fish eyes or does not receive a smooth coating of water, replacing the brush may help restore proper moistening performance.

What This Part Does
The moistening brush transfers water onto the adhesive side of water activated gummed tape as the tape moves through the dispenser. This wetting step is necessary for the adhesive to activate and bond to the carton surface.
When the brush becomes worn, contaminated, or uneven, water may no longer be distributed smoothly across the tape. That can lead to poor tape adhesion, inconsistent wetting, or visible fish eyes on the adhesive surface.
