Arlington Industries DSC5 – Frequently Asked Questions

1) What size duct seal do I need for sealing a few conduit penetrations versus a whole panel job?
Arlington's non-toxic duct seal compound comes in two sizes: a 1 lb block (DSC1) and a 5 lb block (DSC5). The 1 lb is enough for a handful of conduit or raceway penetrations and service-entry seals; the 5 lb is the size to stock on a truck or in an MRO crib when you are sealing panels and utility penetrations across a building. Same compound either way, just the quantity changes.
2) Is Arlington duct seal compound UL listed for electrical work?
Yes, the Arlington duct seal compound carries a UL listing, which is what an inspector or a facilities spec will look for when the material is being used around electrical panels, conduit and service penetrations. It is also made in the United States.
3) Does duct seal harden or cure after you install it?
It doesn't. The Arlington compound stays permanently soft, so it never sets up like a caulk or a firestop putty that cures. That matters two ways on the job: you can pull the seal back out and re-pack the opening if a conductor gets added or a conduit gets moved, and it keeps sealing as the penetration moves seasonally instead of cracking away from the edge. It also means you should not treat it as a permanent structural or bonded seal.
4) Can I use duct seal to fill the gap around a conduit entering an electrical panel?
That is the main use for it. The Arlington compound is meant for sealing around conduit and raceway entries, electrical panel openings and utility penetrations where you need to keep air, dust, moisture and pests out of the enclosure. You hand-pack it into the annular space around the pipe. Because it stays soft rather than curing, it is a weather and air seal, not a firestop, so any penetration through a rated assembly needs a listed firestop product instead.
5) Is this duct seal asbestos free and safe for my crews to handle?
Asbestos free and non-toxic, so it can be handled and packed by hand without the material-safety restrictions that come with older duct seal formulations. That is usually the deciding point for institutional and multi-family maintenance teams that have to document what goes into occupied buildings.
6) Is Arlington duct seal the same thing as electrical putty or a firestop pad?
No. Duct seal is a permanently soft, non-curing compound for weather sealing and pest exclusion at conduit, panel and utility penetrations. Firestop putty pads and sealants are tested and listed for restoring the fire rating of a penetrated wall or floor assembly, which is a different listing and a different product. Use duct seal for the ordinary service-entry and raceway seal; specify a listed firestop where the penetration goes through a rated assembly.
7) How is Arlington duct seal packaged, and do I have to buy a case?
It ships as a single piece, one block per unit, in either the 1 lb or 5 lb size. No case quantity to work around, so you can pick up one block for a single repair or stock both sizes.
8) What is the Arlington part number for 1 lb and 5 lb duct seal?
DSC1 is the 1 lb block and DSC5 is the 5 lb block. Both are the same non-toxic, asbestos-free Arlington compound, so a distributor cross-referencing an order only needs to match the weight.
