Ideal Industries 31-605 Duct Seal, 5 lb. Block

The Ideal Industries 31-605 Duct Seal is a 5 lb. block of moldable, non-hardening sealing compound designed for use by electricians, HVAC technicians, and telecommunications installers who need a dependable way to close gaps around conduit, cable, and duct penetrations. Supplied in a convenient 5 lb. block, this duct seal is easy to portion and shape by hand, allowing installers to pack it into openings, around pipe entries, and inside conduit runs where a pliable, long-lasting seal is required. Because it remains workable rather than curing into a rigid material, the Ideal Industries 31-605 can be reshaped, added to, or removed as job conditions change, making it a practical choice for both new installations and maintenance work.

Key Features

  • Convenient 5 lb. Block: Supplied as a single 5 lb. block for easy handling, portioning, and job-site storage.
  • Moldable, Non-Hardening Compound: Stays pliable after application, allowing installers to shape it by hand into gaps, penetrations, and around conduit or cable entries without the material setting up hard.
  • Reworkable Seal: Because the compound does not cure into a rigid form, it can be adjusted, added to, or removed later if conduit runs or duct penetrations need to be modified.
  • Versatile Application: Suitable for sealing around conduit entries, duct penetrations, cable openings, and similar gaps in electrical and mechanical installations.
  • Professional-Grade Material: Backed by the Ideal Industries name, a trusted brand for electrical contractors and maintenance professionals.

Ideal Industries 31-601 – Frequently Asked Questions

1) Does IDEAL 31-605 duct seal harden after you apply it?
No. It is a non-hardening compound that stays pliable, so you can reshape it, add to it, or pull it out later if a conduit run or duct penetration changes. That is the practical difference from a curing sealant or foam: a maintenance tech can reopen the same penetration without cutting anything out.
2) Can I use duct seal instead of expanding foam around conduit entering a wall?
For closing the gap around conduit, cable, and duct penetrations, the IDEAL 31-605 duct seal is hand-packed into the opening and stays soft, so it blocks air and pest entry while remaining removable. Foam cures rigid and has to be cut out. Duct seal is the choice where you expect to revisit the penetration or add another run through it. It is a moldable sealing compound, not a fire-stop product, so where a rated wall assembly is involved you need a listed firestop material instead.
3) Do you need tools or a caulking gun to apply IDEAL duct seal?
No gun, no mixing. The block is portioned and shaped by hand, then packed into the opening or around the pipe entry. That is why it is handled as a block rather than a cartridge, and why one block covers several openings.
4) Is IDEAL 31-605 the same product as the 1 lb. duct seal, just a bigger block?
Yes, same moldable non-hardening duct seal compound, ordered by block size. 31-601 is the 1 lb. block and 31-605 is the 5 lb. block, so for an MRO stockroom standardizing on one item the only decision is how much material per unit you want on the shelf.
5) What trades use this kind of duct seal block and what for?
Electricians, HVAC techs, and telecom/data installers. Typical uses are sealing conduit penetrations through walls and floors, closing gaps at cable and wire entries, HVAC duct penetrations, telecom and data cabling entry points, and general maintenance or retrofit sealing.
