HoldRite HydroFlame 2-Inch Firestop Collar
The HoldRite HydroFlame 2 Inch Firestop Collar is designed for PVC and related plastics, with a prefabricated sleeve for open and closed through-penetration firestop sealants. It supports PVC, CPVC, FRPP, ABS, and PVC/ABS foam cores. The collar features highly intumescent insulation and requires no curing time, enabling quick, reliable installations in various wall and floor assemblies.
Key considerations include compatibility with common plastic piping and foam insulation cores, ease of installation, and no curing period. This collar provides a compact option for smaller diameter penetrations in both new builds and retrofit work. It is suitable for applications where a rapid, code-compliant firestop solution is needed without long downtime.
HoldRite HydroFlame 3-Inch Firestop Collar
The 3-inch version expands the same concept for larger PVC/ABS penetrations. It is prefabricated for open and closed through-penetration firestop sealants and is compatible with PVC, CPVC, FRPP, ABS, and PVC/ABS foam core insulation. The hydro-flame design emphasizes quick installation with no curing, reducing labor time on projects requiring medium-sized collars.
When selecting this option, consider the diameter of the pipe, the surrounding wall or floor structure, and whether a larger collar better suits the surrounding fire-rating requirements. This model provides a balance between ease of use and broader compatibility for PVC-based plumbing systems.
RectorSeal Metacaulk Intumescent Pipe Collar 66353
This RectorSeal 2-inch intumescent pipe collar is designed for open and closed through-penetration firestop systems with plastic pipes. It is not intended for long-term exposure to rainfall or salt spray. The collar emphasizes easy installation, saving labor costs, and fitting into limited access areas. UL classified for both open and closed pipe systems and is compatible with a range of materials including PVC, CPVC, ABS, FRPP, and PVC/ABS foam core. It supports multiple rated assemblies, including concrete floors and walls, gypsum walls, and wooden floors in specific ratings.
Consider installation environment, exposure to moisture, and the correct ratings for the building envelope. This collar is well-suited for tight spaces where straightforward placement and UL certification are priorities.
RectorSeal Metacaulk Intumescent Pipe Collar 66350
The 3-inch RectorSeal collar provides a robust option for mid-sized PVC and plastic pipe penetrations. It offers easy installation, requiring minimal materials measurement, with intumescent properties that activate under heat. The product is UL listed for both open and closed systems and is designed to work with various substrate types, including concrete floors and walls, gypsum walls, and wood floors. This collar supports multi-material installations and is particularly suitable where space constraints require a compact solution.
RectorSeal Metacaulk Intumescent Pipe Collar 66354
The 6-inch version is designed for larger pipe penetrations and broader firestop coverage. It shares the same benefits of easy installation and UL classification for both open and closed systems. With a high intumescent rating, this collar can be used in larger floor or wall assemblies, including concrete, gypsum, and wood structures. This option suits projects where substantial collar coverage is required to meet fire-rating requirements for PVC and related plastics.
Buying Guide: Key Purchase Considerations
- Fire rating and UL classifications: Verify that the collar is rated for the required fire-resistance level and compatible with open or closed through-penetration systems.
- Pipe and material compatibility: Ensure the collar supports PVC, CPVC, FRPP, ABS, and PVC/ABS foam core insulations where applicable.
- Size and application area: Choose a collar that matches the pipe diameter and the surrounding wall or floor assembly, considering potential future expansions.
- Installation speed: Prefabricated sleeves with no curing time improve throughput on jobs with tight schedules.
- Moisture exposure: Some collars are not suited for long-term rainfall or saltwater spray environments; select accordingly.
- Limited-access scenarios: For spaces with restricted access, prioritize collars advertised for easy installation and minimal measurement requirements.
- Cost vs. coverage: Larger collars provide more coverage but may be overkill for small penetrations; balance cost with the needed rating and size.
- Manufacturer support: Look for products from established brands with clear documentation and installation guidelines.
In evaluating firestop collars for PVC piping, consider the trade-offs between installation simplicity, UL ratings, and the specific pipe materials involved. For smaller penetrations, 2-inch collars from HoldRite or RectorSeal offer quick, reliable protection, while larger penetrations may benefit from 3-inch or 6-inch options to ensure adequate coverage. Always consult project specifications and local codes to confirm the correct product and rating for your installation.
