  • Reliable Solution for Demanding Environments
Size: 1 Pack Color: Clear
As a homeowner who frequently tackles DIY projects and maintenance tasks around the house, I recently had the opportunity to use the Red Devil 0897 Extreme Temperature HVAC/R Silicone Sealant, and I must say, it exceeded my expectations in every aspect. First and foremost, the performance of this silicone sealant is outstanding. Designed specifically for high-temperature applications in HVAC and refrigeration systems, it effectively seals gaps, cracks, and joints, providing a durable and long-lasting solution. I used it to seal leaks in my air conditioning ducts and around my refrigerator's compressor, and it worked like a charm, effectively stopping the leaks and preventing any further issues. One of the standout features of the Red Devil 0897 sealant is its extreme temperature resistance. It can withstand temperatures ranging from -80°F to 550°F (-62°C to 288°C), making it suitable for both cold and hot environments. This versatility gives me peace of mind knowing that it can handle the rigors of fluctuating temperatures without deteriorating or losing its effectiveness over time. Furthermore, I found the application process to be incredibly easy and straightforward. The sealant comes in a convenient squeeze tube, allowing for precise application without the need for any specialized tools or equipment. It has excellent adhesion properties, adhering firmly to a variety of surfaces including metal, glass, ceramic, and most plastics, ensuring a secure and reliable seal. In terms of durability, the Red Devil 0897 sealant has proven to be extremely resilient. Even after prolonged exposure to harsh environmental conditions, it maintains its flexibility and integrity, preventing any air or moisture infiltration. This durability gives me confidence that the seals will remain intact for years to come, reducing the need for frequent reapplications or maintenance. Overall, I am thoroughly impressed with the Red Devil 0897 Extreme Temperature HVAC/R Silicone Sealant. Its exceptional performance, extreme temperature resistance, ease of application, and durability make it a top choice for anyone in need of a reliable sealing solution for HVAC and refrigeration systems. I highly recommend it to homeowners, HVAC technicians, and DIY enthusiasts alike.

  • This stuff is strong
Size: 1 Pack Color: Aluminum
I had to build a custom exhaust ducting for a range hood to fit into some odd spacing. This involved attaching several pieces together. I used this sealant for the transitions and to fill in any transition gaps inside to try to reduce noise as the air from the range hood went through the duct. It is really strong stuff. A couple words of caution 1) do this outside. It really does smell strong 2) wear rubber gloves and long sleeves. This stuff is extremely hard to get off of your skin and especially hair in your arms. ... show more
