3M™ 481 Preservation Sealing Tape features a 9.5 mil black polyethylene backing engineered for equipment preservation, sealing, and long-term protection. The conformable backing adapts to irregular surfaces and complex contours, and the tape meets Military Specification SAE AMS-T-22085 for reliable performance in demanding preservation applications.

This tape is used across military, aerospace, defense manufacturing, and heavy industrial environments where equipment must be protected against moisture, contaminants, and environmental exposure during transit or extended storage. It performs reliably in outdoor and variable-climate conditions, making it a standard choice for preserving vehicles, machinery, and metal components.

The polyethylene construction delivers stain resistance and weatherability rated across a service temperature range of -20°F to 170°F. Each roll is 1 inch wide by 36 yards long, and cases contain 36 rolls. Orders ship via parcel carrier.
