Motorcycle Exhaust Wrap 6/28/2015
Reviewed by: John from San Diego.
Much cleaner look than exhaust wrap. Same temperature specs. Long term endurance not confirmed. Wall thickness comparable to wrap. 1" for smaller exhausts, 1.5 for larger, I personally would not recommend for larger automotive diameter exhausts, only because it probably would not fit.
Excellent Product 8/14/2014
Reviewed by: Andrew from Tomball, TX.
InsulTherm 1.5" is tough and easy to cut. I'm happy with the quality and expect my project to last and last.
Excellent fire protection for gas hoses 5/29/2013
Reviewed by: Deryn from Washington State.
We have a production glassblowing studio and use this sleeving to protect our high pressure gas lines on our hand torches. It works great and can take direct flame and temps that would melt any gas line. It is also very abrasion resistant ant keeps our lines protected from wear and tear.
Great product 5/28/2013
Reviewed by: Chris H from Round Lake, IL.
This is an excellent product when you need high heat resistance. It's able to stand close proximity to manifolds and headers, great for protecting wires.
