Cyvposm Silicone Stove Jack Kit for Bell Tents — Fits 3"–6.25" OD, Heat‑Resistant with Stainless Steel Reinforcement

The Cyvposm Silicone Stove Jack Kit is a heat-resistant, adjustable tent stove collar that creates a protective seal for stove pipes from 3" to 6.25" (7.6–15.9 cm) OD.

If you use a wood or gas stove inside a canvas bell tent, ice-fishing shelter, or other fabric shelter, protecting the fabric where the stove pipe exits is essential. This kit combines industrial-grade silicone with stainless steel reinforcement to give a flexible, high-temperature barrier that you trim and fasten to match your flue pipe diameter. It’s made to reduce direct contact and abrasion between a hot pipe and the tent fabric while keeping installation simple for weekend campers and long-term liveaboards alike.

How does this stove jack protect my tent fabric?

The silicone forms a heat-tolerant sleeve around the stove pipe and distributes heat away from the fabric edge. Stainless steel reinforcement keeps the collar from collapsing and prevents melting or distortion in high heat spots. Used together with a fiberglass flue wrap it extends protection and reduces wear.

• Industrial-grade silicone resists -40°C to 300°C
• Stainless steel layer stabilizes shape and resists direct flame
• Creates a physical gap and abrasion barrier between pipe and canvas
• Recommended: add a fiberglass wrap under the sleeve for longer life

Will this fit my stove pipe and how do I size it?

The collar is designed to cover stove pipe outer diameters from 3" to 6.25" (7.6–15.9 cm). Two sets of clear inch/cm markings on the sleeve let you measure and trim to the precise diameter required. Before buying, measure your pipe OD; you can cut away excess silicone and fasten with the included screws for a snug, custom fit.

• Fits pipes 3"–6.25" OD (7.6–15.9 cm)
• Marked measurements in inches and centimeters on both sides
• Trim-to-fit design for custom diameters
• Includes screws and requires only basic hand tools to install

How straightforward is installation and maintenance?

Installation is intended to be quick and tool-light: align, mark, cut openings, and secure the collar to the tent fabric with the supplied hardware. No specialized stove fitter is required, though careful marking and clean cuts help ensure a weatherproof, centered fit. Maintenance mainly involves visual inspections and replacing the collar if it shows signs of heavy charring or structural degradation.

• Simple align-mark-cut-secure process with included screws
• No special tools required — just a utility knife and screwdriver
• Inspect periodically; replace if silicone becomes brittle or warped
• Extend lifespan by wrapping pipe with fiberglass wrap before installing

What types of tents and situations is this kit suitable for?

This stove jack works with canvas bell tents, ice-fishing shelters, wall tents, and other fabric structures where a rigid stove flue must pass through the roof or wall. It’s designed for camping and seasonal shelters where a durable, removable solution is preferred over permanent fabric modifications. The product is not a substitute for certified stovepipe clearance rules — always follow stove and tent manufacturer safety guidelines.

• Compatible with bell tents, canvas wall tents, ice-fishing and pop-up shelters
• Removable and trim-to-fit for temporary or semi-permanent installations
• Not a replacement for required clearances and stove-specific safety instructions

Who is this for: The Cyvposm Silicone Stove Jack Kit is aimed at outdoor enthusiasts, tent event hosts, winter campers, and anyone running a wood or gas stove inside a fabric shelter who needs a robust, adjustable heat barrier. It suits DIY installers who want a dependable, field-serviceable stove collar that balances high-temperature resistance with simple installation and low ongoing maintenance.
