The US Stove 40292A is a heavy cast-iron piece from a familiar American fireplace brand, designed to endure high heat and provide a snug fit with genuine USSC parts. This collar is well-suited for retrofit projects on traditional stoves that already use cast-iron components.
Who this is best for: buyers replacing a worn collar on an older stove that uses standard 6″ fittings, and homeowners who value brand familiarity and durability. Caution: availability may vary by model compatibility; confirm your stove’s inlet diameter and mounting pattern before purchase.
Flue Collar (40246) – 6″ Cast Iron Replacement
This 6″ cast-iron model is a practical replacement for multiple brands, including Ashley, Breckwell, US Stove, and Vogelzang circulators. Cast iron offers rigidity and heat tolerance, making it a solid choice for mid-range installations. Better for buyers replacing worn collars with a proven material standard.
Best for: homeowners with compatible 6″ stoves seeking a durable, widely compatible replacement. Limitation: designed for 6″ pipes; verify the exact mounting pattern and thickness before ordering.
LEIFIDE 6 Inch Stove Pipe Collar
LEIFIDE’s 6″ collar emphasizes a crimped edge for a tight seal and a carbon steel build with high-temperature coating. The design aims for straightforward installation and a secure fit to prevent smoke leakage. It’s a good pick when the stove pipe requires a precisely aligned, heat-resistant collar.
Best for: buyers prioritizing a tight seal and simple installation. Caution: carbon steel and coating can wear over time in extreme conditions or with aggressive chimney cleaning—inspect periodically for corrosion or edge deformations.
Metal Firewood Stove Pipe Collar, 6″
This 6″ 24-gauge black steel collar combines a clean matte finish with a sturdy single-wall construction. It is intended for use where the flue pipe meets the masonry breech and works well with solid-fuel appliances. Choice for budget-conscious buyers who still want durable steel.
Best for: those replacing a collar near a masonry chimney or upgrading from a lighter metal collar. Limitation: single-wall steel may heat up more on long runs; ensure ventilation and clearance requirements are met.
AllFuelHST Storm Collar for 8″ Pipe
The AllFuelHST storm collar is crafted for 8″ inner-diameter Class-A double-wall chimney pipes. It uses 304 stainless steel for corrosion resistance, a key advantage in challenging weather or high-moisture environments. It seals above flashing to keep water out, making it a solid choice for exterior installations.
Best for: installations requiring superior water sealing and corrosion resistance, especially in outdoor or vent-penetration scenarios. Caution: designed for AllFuel HST 8″ systems; compatibility with other brands may be limited.
Buying Guide: Key Purchase Considerations
- Diameter and fit: Confirm the collar diameter (6″ vs 8″) and whether your stove uses single-wall or double-wall piping. Choosing the wrong size is a common installation issue.
- Material and durability: Cast iron offers rigidity and heat tolerance; steel collars are lighter and budget-friendly but may require more frequent inspection for corrosion or warping. Stainless steel provides corrosion resistance but can be pricier.
- Installation ease: Look for features like crimped edges, pre-punched flanges, or coatings that simplify assembly and reduce gaps where smoke could escape.
- Weather and environment: For exterior or roofline installations, a storm collar that seals above flashing helps prevent water intrusion. Stainless options perform better in humid or coastal climates.
- Brand compatibility: Some collars are designed for specific stove brands or chimney systems. Make sure the collar matches your model’s inlet specifications and mounting pattern.
Frequently Asked Questions

Cast iron is extremely durable; steel collars are affordable and sufficient for many installations; stainless steel offers the best corrosion resistance for outdoor setups.

Measure the stove outlet diameter and verify whether your chimney uses a 6″ or 8″ collar. Check the replacement collar’s compatibility with your stove model.
- Can I install a collar myself?
Yes, with basic tools and careful alignment. Follow manufacturer instructions and ensure all joints are sealed and secured to prevent leaks.

Avoid mismatched diameters, mismatched materials for the chimney type, or collars lacking proper sealing features for outdoor exposure.
