Appleton Century Crofts F04 Fiber Filler 4oz

Fiber Filler for Conduit and Fittings

Appleton Century Crofts F04 Fiber Filler is a white fiber compound supplied in a four-ounce carton. It is intended for electricians and maintenance crews who need to form a positive dam that holds sealing compound inside IMC and RMC conduit systems. The product meets CEC and NEC standards for this application.

Sustained Performance in Temperature Extremes

The filler maintains its damming function across a range from minus twenty-five degrees to forty degrees Fahrenheit. It does not slump or lose cohesion during long cable pulls or while sealant cures, so the barrier remains intact throughout the job rather than only during initial placement.

Thermal Stability and Clean Handling

Because the material is stable across the stated temperature span, it does not soften enough to create mess or stiffen enough to crack in normal ambient conditions. The fiber form stays contained in the carton until use, reducing airborne dust and keeping the work area cleaner during installation.
