Scotch® Super 33+™ Vinyl Electrical Tape, along with the other products in this family, showcases decades of proven, lab-tested innovation. These high-performance electrical solutions are designed to address the daily challenges customers encounter. 3M is committed to delivering high-performance products that help customers enhance application efficiency and effectiveness, featuring aggressive backings and adhesives designed to withstand extreme temperatures and moisture. For best installation practices, apply in half-lapped layers with enough tension to create a uniform wrap. For most applications, when applied properly, this tension will reduce the tape width to approximately 5/8 of its original size. When taping pigtail splices, wrap the tape beyond the ends of the wires and then fold it back to provide a protective cushion against cut-through. For the final wrap, apply the tape without tension to help prevent flagging. Learn more about how Scotch® Super 33+™ Vinyl Electrical Tape can elevate your electrical applications.
What Makes Scotch® Super 33+™ Different?
Premium PVC Backing
Tough, flexible, and resistant to abrasion, UV light, and moisture. This engineered vinyl backing maintains elasticity in cold and heat—so wraps stay smooth and tight even after years in service.
Pressure-Sensitive Adhesive
A proprietary 3M adhesive that instantly bonds to cable jackets and itself, forming a uniform, air-tight seal. Engineered to prevent flagging, maintain adhesion, and resist corrosion.
High-Stretch Core
Stretches up to 250% of its length to conform around irregular surfaces, then recoils to maintain constant pressure. Creates a tighter wrap, stronger seal, and smoother finish.
