Professional gray sealing tape with 25 mil thickness, acrylic adhesive, and TPO backing for durable outdoor and industrial sealing applications with instant adhesion and superior weather resistance.
3M™ Extreme Sealing Tape 4410G+ is a professional-grade sealing solution designed for quick and clean sealing applications across industrial and outdoor environments. This gray, 0.025 inch (0.6 mm) thick tape features a single-coated acrylic adhesive on a durable thermoplastic polyolefin (TPO) backing, delivering both excellent conformability and instant adhesion. The tape eliminates the need for messy caulking equipment, cartridges, and the associated cure time, mess, and oozing problems of traditional liquid sealants.
Engineered to overcome the challenges of exterior sealing, this tape delivers superior resistance to sun, rain, extreme temperatures, vibration, and thermal expansion or contraction. Its flexible TPO backing conforms perfectly over fasteners, seams, joints, holes, and gaps, making it ideal for applications such as cargo trailer rail seals, HVAC enclosures, roof sealing, and exterior side panel sealing. The linerless design eliminates traditional liner waste, supporting sustainability goals without compromising performance.
With a maximum operating temperature of 93°C (200°F) and application temperature starting from 10°C, this water-tight, UV-resistant tape provides reliable performance in both indoor and outdoor environments. Available in multiple colors and thicknesses, 3M™ Extreme Sealing Tape 4410G+ represents a modern advancement in sealing technology, combining ease of application with exceptional durability and long-term reliability for demanding industrial applications.
