3M 2155-3/4X22FT – Frequently Asked Questions
1) Can 3M Temflex 2155 splicing tape be used outdoors or in direct sunlight?
No. Temflex 2155 rubber splicing tape is not UV resistant, so it should not be left exposed to sunlight as the outer layer. For outdoor splices, overwrap it with a UV-resistant vinyl electrical tape so the rubber tape is fully covered.
2) Is rubber splicing tape the same thing as regular vinyl electrical tape?
No, and they do different jobs. Temflex 2155 is a rubber splicing tape, 0.76 mm thick, used to build up insulation and pad out a splice or termination so the wrap matches the original insulation level. Vinyl electrical tape is thinner and used for jacketing, color coding, and the protective outer layer. On a typical splice you use the rubber tape first for insulation, then a vinyl tape over it for mechanical and weather protection, which also covers the fact that the 2155 is not UV resistant.
3) What temperature can 3M Temflex 2155 rubber splicing tape handle?
Temflex 2155 is rated to a maximum operating temperature of 80 degrees Celsius (176 F). That covers normal building wiring, motor leads, and industrial maintenance splices, but it is not the tape for splices running hotter than that, such as high-temperature furnace or oven wiring.
4) How many layers of rubber splicing tape do I need on a wire splice?
Temflex 2155 measures 0.76 mm per layer, and half-lapping a wrap puts roughly two layers of tape down per pass. Build the wrap up until the splice insulation is at least as thick as the original conductor insulation, then jacket it with vinyl tape. A 22 ft roll gives enough length to build up several splices on typical building wire.
5) How tough is Temflex 2155 when stretching it around a connector?
The tape carries a 300 pound tensile strength rating, so it takes the stretch that rubber splicing tape needs to fuse to itself around a connector body without tearing mid-wrap. Its rubber backing is conformable, which is what lets it pad irregular shapes like split bolts and lug barrels.
6) Does 3M Temflex 2155 come in any color other than black?
Black only. If you need colored tape for phase identification, use a vinyl color-coding electrical tape over the finished splice; the 2155 is the insulating layer, not the identification layer.
7) Is Temflex 2155 sold by the roll or by the case?
Rolls of Temflex 2155 ship in bulk case packaging, which is how electrical contractors and MRO storerooms usually stock a high-use consumable like splicing tape. Each roll in the case is 22 ft long in the width you select.
