3M™ 481 Preservation Sealing Tape is a 9.5 mil black polyethylene-backed tape engineered for long-term sealing and protection of equipment, vehicles, and machinery during storage and transit. Its conformable backing adapts to irregular surfaces and contours, allowing consistent adhesion across complex profiles without bridging or lifting.

The tape's rated service range of 20°F to 170°F makes it viable in cold storage warehouses, outdoor staging areas, and high-heat industrial environments alike. Stain-resistant construction and proven weatherability extend its suitability to long-duration storage and outdoor preservation scenarios common in defense depots, aerospace maintenance facilities, fleet operations, and heavy equipment storage yards.

Compliance with SAE AMS-T-22085 makes this tape a documented, specification-driven choice for defense, government, and aerospace procurement. Each case contains 24 rolls and ships via parcel carrier.
