HoldRite HydroFlame 3 Inch Firestop Pipe Collar
The HoldRite HydroFlame 3 Inch Firestop Pipe Collar is designed for open and closed through-penetration firestop sealants. It supports PVC, CPVC, FRPP, ABS, and PVC/ABS foam core insulation, making it a versatile option for common PVC installations. The collar is highly intumescent, meaning it expands when exposed to heat to block fire and smoke from spreading through penetrations. A key advantage is its quick and easy installation, with no curing time required, reducing job site downtime and labor costs.
HoldRite HydroFlame 2 Inch Firestop Pipe Collar
This 2 Inch model mirrors the same core features as the 3 Inch option: prefabricated firestop sleeves for open or closed penetrations, compatibility with PVC, CPVC, FRPP, ABS, and PVC/ABS insulation, and rapid intumescent action. Its streamlined size enables installation in tighter spaces while still delivering reliable fire protection. Quick installation without curing time helps maintain schedule integrity on commercial and residential projects alike.
HoldRite HydroFlame 1-1/2 Inch Firestop Pipe Collar
The 1-1/2 Inch HoldRite model offers flexibility for smaller penetrations common in residential plumbing or retrofit projects. It maintains the same firestop principles—prefabricated sleeves, broad material compatibility, high intumescence, and no curing requirement. Its compact profile is advantageous for installations near tight corners or existing conduits, helping to minimize disruption while maintaining fire-rated integrity.
Rectorseal 66353 2-Inch Metacaulk Pipe Collar
Rectorseal’s 2-Inch Metacaulk Pipe Collar emphasizes a straightforward locking mechanism intended to simplify installation. The design aims to cut through installation time and reduce labor costs while providing reliable firestop performance for through-penetrations. This collar works well with PVC, CPVC, ABS, and PVC/ABS foam core materials, aligning with typical PVC piping systems and insulation types used in American construction.
Rectorseal 66350 3-Inch Metacaulk Pipe Collar
The 3-Inch Metacaulk Collar from Rectorseal extends the same reliability to larger PVC penetrations. It features an easy locking mechanism and is designed to reduce installation time and overall project costs. It’s suitable for through-penetration firestop systems with common plastics, including PVC, CPVC, ABS, and PVC/ABS foam core insulation, making it a practical choice for apartments, schools, or commercial builds where larger pathways exist.
Additional Rectorseal Options
Rectorseal also offers the 6-inch Metacaulk Intumescent Pipe Collar 66354, which fits well in limited-access areas and is UL classified for both open and closed pipe systems. While designed for larger spaces and higher ratings, it shares the same core principles: simple installation, effective fire stopping, and compatibility with multiple plastic piping materials.
Buying Guide: Key Purchase Considerations And Comparisons
When choosing a fire collar for PVC pipe, consider these factors to ensure you select the best option for your project:
- Material compatibility: Verify the collar supports PVC, CPVC, FRPP, ABS, and PVC/ABS foam cores, as listed by each product. This ensures it will work across common piping configurations.
- Size and application: Match the collar diameter to the pipe size and the rated fire exposure. Larger penetrations require bigger collars, while retrofit jobs benefit from compact models that fit tight spaces.
- Firestop performance: Look for intumescent properties that expand under heat. This is crucial for creating effective fire barriers and limiting smoke passage.
- Installation ease: Prefabricated sleeves and simple locking mechanisms reduce labor time and on-site errors. No curing time is a key advantage for fast-track projects.
- UL/classification and code compliance: Ensure the collar is UL listed or classified for open/closed penetrations and compatible with building codes in your area. This supports long-term safety and pass-through inspections.
- Brand and availability: Established brands like HoldRite and Rectorseal provide broad support and readily available replacements, which can minimize project delays.
- Environmental exposure: For outdoor or harsh environments, check the collar’s ability to withstand rainfall, salt spray, and temperature variations if specified by the manufacturer.
- Cost vs. value: Compare installation time savings and material quality. A higher upfront cost may pay off through reduced labor and faster project completion.
In summary, these five selections offer a balance of compatibility, ease of installation, and fire protection performance for PVC and related piping. Contractors should weigh space constraints, required fire ratings, and local code requirements when selecting the right collar for a given penetration.
