What is the heat rating of Insulation Snakes®?
Insulation Snakes® can withstand temperatures up to 205 degrees Fahrenheit or 96 degrees Celsius. At this temperature, the polyethylene sheathing will begin to soften. Higher temperatures will cause it to melt away from the heat source. See data sheet.
Can I cut the snake to the length that I require?
No, you should never cut the Insulation Snake® because the ends are sealed to help keep moisture and rodents out.
Can I use a steamer on Insulation Snakes®?
Do not direct the steam directly at the Insulation Snake® as it will quickly cut a hole through the polyethylene. Do not touch the snake with the steamer wand, or it will melt the polyethylene outside of the Insulation Snake®.
What should I use to fasten the snake on the piping or equipment?
SNAKE STRAPS are recommended for Insulation Snakes® that don’t already have attached straps. Snake Straps allow for quick and easy installation and removal without damage to the Insulation Snakes®. Do not use tape, wire or zip ties as this may reduce your R-value and may also make removal difficult, resulting in damaging the Insulation Snakes®.
Can you make an Insulation Snake® to fit my application?
Yes, send us pictures or drawings with measurements and we will custom build to suit your particular requirements.
