3M 2228-2X3FT Rubber Mastic Tape 23 Ft Electrical

Product DescriptionThe 3M 2228-2X3FT is a rubber mastic electrical insulation tape designed for sealing, insulating, and moisture-proofing splices and connections in electrical systems. This tape conforms readily to irregular surfaces and self-fuses to create a void-free insulating layer over cable splices, terminations, and connectors. It is widely used by licensed electricians and electrical contractors working on medium-voltage cable joints and wire splices where moisture ingress and mechanical protection are critical concerns.This tape is appropriate for both indoor and outdoor electrical applications. Electricians commonly apply it over primary insulation on spliced cables, at termination points, and around connectors exposed to moisture or environmental stress. At 2 inches wide and 3 feet in length, this roll size is suited to single-splice or limited-run applications where a full-size roll is unnecessary.Key FeaturesRubber mastic construction conforms to irregular and uneven splice geometriesSelf-fusing material creates a void-free insulating wrap without adhesiveResistant to moisture, corrosion, and environmental exposure2-inch width is compatible with standard cable splice and termination profilesCompact 3-foot roll length suits single-splice field applicationsCompatibilityDesigned as an OEM-style insulating tape for use on electrical cable splices, terminations, and connectors in residential and commercial electrical installations where rubber mastic sealing is required.Installation NotesInstallation is performed by a licensed electrician following applicable NEC requirements. De-energize and lock out the circuit before beginning any splice or termination work. Apply the tape with a half-lapped wrap, stretching slightly to activate conformability and ensure void-free coverage. Do not apply over contaminated or wet surfaces.Technical SpecificationsTape Width: 2 inchesTape Length: 3 feetTape Type: Rubber Mastic Electrical InsulationUPC: 05400743478Standard InformationBrand: 3MManufacturer Part Number: 2228-2X3FT
