3M™ Fire Barrier CP 25WB+ Caulk is a premium elastomeric latex caulk designed for use as a one-part fire, smoke, noxious gas and water sealant. In addition, the unique intumescent property of this material (expands when heated) means that as cable or pipe insulation is consumed by fire, CP 25WB+ Caulk expands to maintain the penetration seal.

Installation Techniques

Shown are examples of approved applications of CP 25WB+ Caulk. Additional drawings and details are available through your Authorized 3M Fire Protection Products Distributor.

Installation Notes:

  1. Metal Pipe/Conduit applications through nominal 12 in. (304,8 mm) outside diameter
    • Installed depth of CP 25WB+ Caulk depends on annular space.
    • When the annular space is less than 1-1/4 in. (31,8 mm), a 1/2 in. (12,7 mm) minimum depth of CP 25WB+ Caulk is required.
    • When the annular space is greater than 1-1/4 in. (31,8 mm), a 1 in. (25,4 mm) minimum depth of CP 25WB+ Caulk is required.
    • Common building materials, such as backer rod may be used for metal pipe applications.
  2. Metal Pipe applications larger than nominal 12 in. (304,8 mm) outside diameter.
    • All cases require a 1 in. (25,4mm) minimum depth of CP 25WB+ Caulk.
  3. Insulated Cable Applications.
    • All cases require a 1 in. (25,4mm) minimum depth of CP 25WB+ Caulk.
    • All cases require mineral wool (safing) for packing.
  4. Fiberglass Insulated Pipe Applications.
    • 1 in. (25,4 mm) of fiberglass insulation on up to a nominal 12 in. (304,8 mm) of metal pipe may be firestopped with a 1 in. (25,4 mm) depth of CP 25WB+ Caulk.
    • 1 in. (25,4 mm) depth of mineral wool packing required

Q:tubing

Can this be used on pex tubing

Asked by Anonymous user on

A:Answers

  • - Thank you for your question. I believe this item is designed to work with rigid surfaces, flexible things like PEX tubing would not benefit from this product.
