Metacaulk® Pipe Collars

Metacaulk® Pipe Collars are a cost-effective and labor-saving solution for firestopping plastic pipes in through-penetration scenarios. Their key features and details include

Key Features

• Prefabricated System: Ready to install, eliminating the need for measuring and applying messy sealants in the initial installation phase.
• Easy Installation: Features a simple locking tab mechanism that allows for quick and efficient installation around the pipe.
• Economical: Reduces labor costs compared to traditional firestopping methods.
• Highly Intumescent: The internal intumescent material expands significantly when exposed to heat from a fire, forming a dense char that closes off the opening and prevents the passage of flames and smoke. Expansion begins around 375°F (190°C) with the greatest expansion occurring between 575°F - 1100°F (302°C - 593°C).
• Tested for Various Plastic Pipes: Classified by Underwriters Laboratories (UL) for use with PVC, CPVC, ABS, PVC/ABS Foam Core, FRPP, and PP pipes.
• UL Classified for Open and Closed Pipe Systems: Suitable for both closed (pressurized) and vented (DWV - drain, waste, vent) plastic pipe applications.
• Various Sizes: Available in sizes ranging from 1 1/2" (38 mm) to 6" (152 mm) to accommodate common plastic pipe diameters.
• FBC System Compatible: Indicates that the product has been tested and is monitored on an ongoing basis to assure its chemical compatibility with FlowGuard Gold®, BlazeMaster®, and Corzan® pipe and fittings.    
• Complies with Environmental Exposure Testing: Meets the requirements of UL 1479 for accelerated aging and high humidity.
• Fits in Limited Access Areas: The design allows for installation even in tight spaces.

Applications

• Sealing off combustible plastic pipes (PVC, CPVC, ABS, FRPP, PVC/ABS foam core, PP) penetrating:
  • Concrete floors and walls (up to 3-hour fire rating)
  • Gypsum walls (up to 2-hour fire rating)
  • Wood floors (up to 2-hour fire rating)
• Ideal for use in both open and closed (pressurized) piping systems.
• Suitable for various plumbing, drain, waste, vent, and other plastic piping applications.
• Can be used in conjunction with Metacaulk® 1000 sealant within the annular space for an additional smoke seal if required.

Installation

1. Select the proper collar size to fit the diameter of the pipe.
2. Ensuring the annular space is within the limits specified in the tested conditions, attach the collar around the pipe on the underside of the floor or to each side of a wall. Firmly place the collar against the wall or floor and secure the interlocking tabs (for 1 1/2", 2", 3", and 4" collars) or fasten the anchoring tabs (for all sizes).
3. If needed, mark and predrill the wall or floor for required anchors. Secure appropriate anchors into each anchoring tab. Recommended anchors include concrete anchors (1/4" x 1 1/4" hex washer head or steel expansion/wedge type) or hollow wall anchors/drywall screws with fender washers for gypsum.
4. If an additional smoke seal is required, Metacaulk® 1000 may be applied within the annular space before attaching the collar.
5. Consult the UL Directory for complete installation instructions and specific system listings.

• Not for use in outdoor environments where long-term exposure to rainfall or saltwater spray may occur.
• No other limitations known if used as directed.
