Purpose-built conduit filler

Killark PF-2 IMC fiber mineral wool is a gray sealing compound designed for use with intermediate metal conduit and rigid metal conduit systems. The product forms a positive dam that holds sealing compound in place during installation. It meets CSA 22.2 No. 18 and UL 886 standards for electrical fittings.

Two-ounce bag format

The 2 oz bag provides a measured amount of fiber filler for individual conduit sealing jobs. The bag container keeps the mineral wool clean and dry until it is needed on site. The gray color matches typical conduit finishes for a consistent appearance.

Installers sealing IMC and RMC runs

Electricians and maintenance crews who need to create code-compliant seals in intermediate or rigid metal conduit will find this filler suitable. The temperature range of -40 degrees to 65 degrees F supports outdoor and indoor applications. Buyers who require a different container size, a liquid sealant, or a product rated for other conduit types should look at alternative sealing solutions.

Questions about this item

How often does the mineral wool filling need replacement after installation?

The fiber filler forms a permanent positive dam for sealing compound and is not a consumable item requiring periodic replacement.

What temperature limit affects continuous performance of the PF-2 coupling?

The product is rated for operation between -40 degrees and 65 degrees Fahrenheit, so sustained exposure above 65°F is the limiting factor.

Does the gray fiber filler generate heat or noise during all-day conduit sealing use?

The mineral wool fiber is a passive sealing material with no moving parts, electrical load or exothermic reaction, so it produces no heat or noise.
