A wire harness near my battery was unraveling, the cloth outer wrap fraying back about two inches, exposing the bundle underneath. Regular electrical tape wasn’t going to survive there; it goes gummy the moment engine heat soaks in. This high temp wire harness tape is the cloth-wrapped, heat-rated alternative built for exactly that spot, and it fixed the problem in under a minute.
Quick Verdict
I spotted a harness fraying near my battery, tore off one piece by hand, and had it wrapped tight in about 20 seconds. Two rolls, 100 feet total, and it stayed put in a spot my fingers barely fit into. That’s the whole pitch for this high temp wire tape, and it delivered.
Buy if you:
- Have loose or unraveling wiring under the hood you want to neaten up
- Work in tight engine-bay spots where scissors are useless
- Want cloth tape that handles engine heat, not just electrical tape
- Like keeping a repair roll in the glovebox for quick fixes
Skip if you:
- Want a slick pre-cut roll, you tear this off in strips, so wrapping a whole harness the traditional spool way is trickier in cramped spots
- Need something rated way past 250β for a header or exhaust wrap
- Only ever tape indoor cords and don’t care about heat resistance

The Fraying Harness That Started This
The 2 Rolls High Temp Wire Harness Tape comes as two complete rolls, and I believe each roll is probably about 50 ft, so you’re getting 100 feet total. For something that fixes a job in seconds, that’s a lot of tape to work through.
What This High Temp Wire Tape Actually Is
It’s cloth tape rated from -40β to 250β, built to match OEM wire harness wrap. In your hand it feels closer to a fabric bandage than a roll of tape, woven, slightly textured, with enough body that it doesn’t stretch and slip when you press it down. That construction is what lets it do two things vinyl tape can’t: hold a bundle’s shape under vibration and stay adhered when engine heat climbs past the point where standard electrical tape turns into a sticky mess.
The Tear-By-Hand Trick Is the Best Part
You tear it to the exact length you need, and it doesn’t rip until you’re ready. That’s the feature I love. As I opened this up by hand, I could just tear it, and it’s pretty strong, so it doesn’t come apart until I decide to pull. It gives me the exact size I need without hunting for scissors. Out at the car, I had a little bit of my harness right around the battery area starting to unravel. I was going to wrap it around the roll, but it’s a tight space, so I just tore a piece off instead.
That one move is what makes this tape worth keeping around. In a cramped engine bay you don’t have room to spin a full spool, so being able to grab a short strip and press it down is the whole game.
Wrapping the Battery-Area Harness
All I had to do was secure the piece that was unraveling, and I got a good fit first try. The tape is small enough that I could kind of get up in that tight area right there, wrap the frayed section, and press it down. After that I had no frayed areas on my wiring harness at all. Nice and neat, so it won’t unravel when I don’t want it to. It secures like it’s supposed to, and it stuck even in a spot I could barely reach with two fingers.
The adhesive grabs fast, which matters when you’re working one-handed under a hood. I wasn’t fighting it or re-sticking it three times. One pass and the frayed wrap was locked down.
The One Thing You Learn Fast
Because you tear it into strips, patching short frayed spots is easy, but fully re-looming a long harness the traditional spool way is fiddly in tight spaces. I wanted to wrap it around the roll like a proper harness wrap, and I couldn’t, so I tore a piece off instead. That worked great for my repair, but if you’re rebuilding a whole run of wiring you’ll be tearing and pressing a lot of separate strips rather than spinning one continuous wrap. Not a deal-breaker, just something you figure out the first time you’re in a cramped bay.

Who This Is For
This is for the DIY person who pops the hood and spots something rattling apart. I had stuff rattling under mine, and this fixed it in one shot. If you keep an older car running, or you just want a tidy engine bay, a roll of high temp wire tape stays handy for quick roadside repairs. It also doubles for appliance cords and household wiring, so it’s not strictly a car thing. I’d probably keep one of these in the car with me at all times, which tells you where it fits: quick roadside or driveway repairs where you need heat-rated wrap right now.
Cloth Tape vs. Regular Electrical Tape
Regular electrical tape gets gummy and slides off under engine heat. That’s the whole reason this exists. Basic vinyl electrical tape isn’t rated for a hot engine bay, and it can unravel into a sticky mess when it warms up. This cloth harness tape is built for -40β to 250β and stays put. The trade-off is it’s not a stretchy insulating tape for electrical splices, so if you’re actually joining bare conductors you still want proper electrical tape or heat shrink for the connection, then this over the bundle. Different jobs. This one wins on holding a harness together in the heat.
Tips Before You Wrap Your Engine
Wipe the wires down first if they’re greasy, because the adhesive grabs way better on a clean surface. Tear your strip before you reach into the tight spot, not after, since it’s easier to size the piece with both hands free. And overlap each pass a little so the ends don’t peel. For a fraying section like mine, one short strip did it. At the price point this two-pack typically sits at, you’re paying less than a dollar per 10 feet of heat-rated cloth wrap, hard to argue with that for something you’ll reach for every time a harness starts to fray.

Pros
- Tears by hand to the exact length, no scissors needed
- Strong enough that it doesn’t rip until you pull it
- Sticks fast and holds in tight, hard-to-reach engine-bay spots
- Rated -40β to 250β for real engine heat, unlike basic electrical tape
- Two rolls, 100 ft total, and it’s inexpensive
Cons
- You tear strips rather than spool-wrap, so re-looming a long harness in a cramped space is fiddly
- Not an insulating tape for bare electrical splices
- 250β ceiling means it’s not for exhaust or header wrap
Frequently Asked Questions
How much tape do you get in the two-pack?
You get two complete rolls, roughly 50 ft each, for about 100 ft total. That’s enough for a lot of small harness repairs before you’d ever run out.
Does the adhesive leave a sticky residue like duct tape?
It’s a cloth harness tape designed to stay bundled, not a gummy vinyl tape, so it grips the bundle rather than gooing up. Wipe wires clean first for the best bond. If you peel it later, cloth harness tapes are generally cleaner to remove than duct tape.
Can I use it on household appliance cords, not just cars?
Yes, it doubles as a cord organizer for appliances and household wiring. The heat rating just means it’s overbuilt for those calmer indoor jobs, which is fine.
Is it safe near a hot engine?
It’s rated to 250β, which covers most engine-bay wiring runs. Keep it away from direct exhaust, headers, or turbo housings, since those get far hotter than this tape is built for.
Do I need scissors or a knife to cut it?
No, it tears cleanly by hand. That’s one of the best parts, since you can size a strip one-handed in a tight spot without digging for a tool.
Will it work as electrical insulation for a wire splice?
Treat it as harness wrap, not splice insulation. For a bare connection use proper electrical tape or heat shrink first, then wrap the finished bundle with this cloth tape.
How is it different from high temp silicone or high temp grease products?
Different tool for a different job. High temp silicone seals and high temp grease lubricate, while this tape bundles and protects wiring from heat, vibration, and abrasion. They can all live in the same engine bay without overlapping.
Does it resist abrasion where wires rub against metal?
Yes, it’s built for puncture and abrasion resistance, which is a big reason to use it where a loom crosses a bracket or sharp edge. That rubbing is exactly what frays wires over time.
