Product Information

Full details

The Chimsoc High Temperature Rubber Pipe Flashing is designed for professional contractors and DIY enthusiasts needing a reliable, heat-resistant seal for pipes passing through roofs. Its primary strength lies in its specialized silicone rubber construction that handles extreme temperature fluctuations, making it ideal for wood-burning stoves and high-heat flue systems. While it provides excellent versatility with its adjustable diameter range, users should ensure the roof surface is clean and compatible with the flashing's mounting base to maintain a watertight seal.

FAQs

What is the temperature range for this flashing?

It is rated for continuous use between -50 and +225 degrees Celsius and can withstand intermittent spikes up to 260 degrees Celsius.

Can this be used on a flat roof?

Yes, it is designed to accommodate roof pitches from 0 degrees (flat) up to 40 degrees.

How do I determine where to cut the rubber?

The cone features clearly marked diameter lines that you can trim using a sharp utility knife to match your pipe size.

Is this flashing UV resistant?

Yes, the silicone rubber is specifically formulated to resist UV radiation and ozone, ensuring longevity in outdoor environments.

Does the flashing come with screws or sealant?

No, you will need to provide appropriate weather-rated fasteners and high-temperature roofing sealant based on your specific roof material.

What is the maximum pipe diameter this can handle?

The flashing is designed to fit pipe diameters between 95mm and 197mm.

Troubleshooting

Water leakage around the base of the flashing

Ensure the roof sealant was applied continuously without gaps and that all fasteners are tightened securely to compress the base against the roof surface.

Difficulty fitting the cone over the pipe

Apply a small amount of dish soap or specialized rubber lubricant to the pipe to help the silicone slide into position without overstretching the material.

Pros and Cons

Pros

  • Wide operating temperature range suitable for high-heat stove flues
  • Flexible cone design accommodates a broad range of pipe sizes (95-197mm)
  • Excellent durability against UV and ozone degradation
  • Capable of conforming to various roof pitches up to 40 degrees

Cons

  • Not intended for non-heat-resistant standard piping if high heat is not a factor
  • Requires proper sealing materials for the base to ensure a watertight bond
  • Specific diameter range limits usage on very small or exceptionally large flues

Setup, Compatibility & Care

  1. Preparation: Clean the roof surface thoroughly around the pipe penetration to ensure a debris-free mounting area.
  2. Sizing: Cut the rubber cone at the required diameter marking (95mm to 197mm) to match your specific flue pipe size.
  3. Sealing: Apply a high-quality, heat-resistant roofing sealant to the underside of the 275mm x 275mm base before securing it to the roof deck.
  4. Fastening: Secure the base using appropriate weather-rated screws or rivets, ensuring the fasteners are spaced evenly to compress the sealant.
  5. Maintenance: Periodically inspect the silicone rubber for any signs of physical damage or degradation every 12 months, especially after extreme weather events.
