AC PERFORMANCE Black 1 ID Silicone Coated Fiberglass Heat Shielded Fire Sleeve for Hose Lines & Electrical Wiring, 1 inch ID, 3 Feet (25 mm ID)

High quality product. Does its job and does it well. Great buy!

Tested on spark plug wires and does its job

I had to stretch it out to make it fit a ½ hose. Seems to be the case with all insulation like this though.

This is replacing orange sleeve in picture that is same but larger. The sleeve will protect fuel lines from heat and wear.

worhs well

Easy to use easy to put in place thats what I wanted & thats what I got.i need more & intend to order more.

LM7 5.3L with Long tube headers. I had to modify my oil dipstick (well re-manufacture one) out of 6AN hose and the upper and lower portions of the OEM dipstick. If you have headers there isnt a good way to install the stock dipstick unless you bend the heck out of it and risk snapping the bottom off.

Works great I used it on a vacuum line on my wastegate, used on -4an nylon braided line

Am using in my car to cover turbo vacuum lines and they hold up great
