- Professional
The heavy-duty sibling to Super 33+, with a thicker 8.5 mil backing for extra abrasion and puncture resistance on demanding jobs. UL 510 listed to 600V across a wide -18C to 105C range, it excels on outdoor and cold-weather splices. It costs the same premium as 33+ and the added thickness trades a little conformability for toughness.
Pros
- Thicker 8.5 mil backing is more abrasion- and puncture-resistant than 7 mil tapes
- UL 510 listed to 600V with a wide -18C to 105C range
- Excellent UV, moisture, and cold-weather performance for outdoor splices
Cons
- Priciest of the common vinyl tapes alongside Super 33+
- Extra thickness makes tight conformability slightly harder in cramped boxes
- Only 3/4 in wide, so large wraps take more passes

Frequently Asked Questions
- What is the difference between 3M Super 88 and Super 33+?
- Thickness, mainly. Super 88 uses an 8.5 mil backing against 7 mil on standard tapes, which makes it more abrasion- and puncture-resistant and better suited to outdoor splices. Both are premium 3M vinyl tapes at a similar price; the extra body is what you are buying.
- Is Super 88 rated for outdoor use?
- Yes. It is UL 510 listed to 600V with a rated range of 0F to 221F (-18C to 105C) and has excellent UV, moisture and cold-weather performance, which is why it gets specified for outdoor and cold-weather splices.
- Is the extra thickness ever a disadvantage?
- In cramped boxes, yes. The thicker backing conforms slightly less easily around tight bends and crowded terminations, where a thinner tape wraps more neatly. At only 3/4 in wide, large wraps also take more passes.
- Is it worth paying more than a bargain vinyl tape?
- For anything electrical that matters, yes - it is UL 510, CSA and VDE listed and flame retardant, which bargain tapes generally are not. It is the priciest of the common vinyl tapes alongside Super 33+, at roughly $8 for a 3/4 in x 66 ft roll.
