3M 35-VIOLET-3/4X66FT 35-Violet-3/4 Vinyl Color Coding Tape 3/4" x 66'

Scotch 35 is a premium grade vinyl electrical tape rated 1250 V/mil dielectric strength, so it insulates as well as it marks. It is rated for low voltage applications. Most crews use it for phase identification, color coding leads and piping, and marking safety areas, and it holds up as insulation on low voltage work because of the PVC backing and rubber resin adhesive.

Yes. The 35 vinyl color coding tape is UL Listed and CSA Certified, and also carries VDE 0340-TEIL1. It is RoHS 2011/65/EU compliant without exemption, which matters if your spec calls for RoHS documentation on installed materials.

The 35 tape is UV resistant and rated for 0 to 105 degrees C (32 to 220 F), so exterior runs and hot equipment rooms are fine. The bottom of that range is the limit to watch: at freezing and below it is outside its rated operating range, so unheated warehouses or winter exterior work in cold climates are not where this tape belongs.

Each roll runs 3/4 inch (19 mm) wide by 66 feet (20 m) long, at 7 mil (0.177 mm) thick. The 3/4 inch width is the common size for wrapping around conductors and small conduit; the 7 mil build is the standard premium vinyl thickness, so a half-lapped wrap gives you roughly 14 mil of coverage.

Both are 7 mil premium vinyl electrical tapes from the same Scotch line, and the 35 is the color coding member of that family, offered in violet among other colors. The practical difference is the temperature range: the 35 is rated 0 to 105 C. Crews that use 33+ for general insulating typically keep 35 on the truck purely for phase marking and identification.

Yes, piping is a listed use alongside phase identification and safety area marking. The vinyl backing is abrasion and weather resistant and the tape is UV resistant, so banding on exposed pipe runs holds its color and its grip. Confirm the pipe surface sits within 32 to 220 F before you band a hot or chilled line.

Violet is one of the nine colors in the Scotch 35 color coding line, used to mark a specific conductor, circuit, piping system or safety zone under whatever coding scheme the facility has standardized on. There is no single universal meaning for violet, so it is commonly assigned in-house for a system that falls outside the standard black/red/blue and brown/orange/yellow phase sets. If you are standardizing a building, write the legend down and stock the matching colors.

The manufacturer part number is 35-VIOLET-3/4X66FT, in the Scotch Vinyl Color Coding Electrical Tape 35 family. That number encodes the color and the roll size, so the color and the 3/4 inch by 66 foot dimensions change with the part number, not with an option on the order.
