Red Devil 0912 Triple Expanding Foam Sealant 20 Oz

Product Description

The RED DEVIL 0912 is a triple-expanding polyurethane foam sealant designed to fill and seal cracks, gaps, and small voids in residential and commercial construction. The formula expands aggressively after application to maximize void fill, then cures firm to create a durable, airtight seal. Curing requires exposure to air humidity, making ambient moisture a key factor in set time. The 20 oz aerosol format delivers controlled, one-hand application directly from the can. This product is used by insulation contractors, plumbers, HVAC installers, and general contractors for air sealing and penetration fill work.

This expanding foam sealant is suited for sealing pipe penetrations, conduit entries, duct openings, and structural gaps in walls, floors, and ceilings. It works on common construction substrates including wood, masonry, drywall, and metal framing. Typical applications include sealing around plumbing rough-ins, electrical conduit pass-throughs, and HVAC line set penetrations where an airtight, insulating fill is needed.

Key Features

Compatibility

Designed as a general-purpose expanding foam sealant for use in residential and light commercial construction, penetration sealing, and air barrier applications across HVAC, plumbing, and electrical trades.

Installation Notes

This product should be applied in a well-ventilated area, as uncured polyurethane foam releases isocyanate vapors during expansion and cure. Installers should wear gloves and eye protection, as uncured foam bonds aggressively to skin and clothing. Shake the can thoroughly before use and apply at moderate temperatures for optimal expansion. Allow the foam to cure fully before trimming any excess flush with the surrounding surface.
