3M 7000048438 Polyethylene Tape 2 in X 36 Yd 5.1 Mil

Product Description

The 3M 7000048438 is a transparent polyethylene tape designed for moisture protection, surface masking, and general-purpose sealing applications in mechanical and construction trades. At 5.1 mil gauge, the film backing provides reliable conformability and tear resistance across a range of substrate types. The tape ships in a standard roll format and is suited for technicians and tradespeople who need a clean, low-profile seal or protective layer without added bulk. Each roll measures 2 inches wide by 36 yards long, offering substantial coverage per unit.

This polyethylene tape is used across HVAC, plumbing, and general construction applications where a moisture-resistant, flexible barrier is needed. Common uses include pipe wrap, vapor barrier seaming, surface protection during finishing work, and temporary sealing on ductwork or mechanical assemblies. Its transparent film allows visual inspection of the covered surface without removing the tape, making it practical in diagnostic and inspection workflows.

Key Features

• 5.1 mil polyethylene film backing for durability and conformability
• Transparent film allows surface inspection without tape removal
• 2-inch width suits standard pipe, duct edge, and surface masking tasks
• 36-yard roll length provides extended coverage per roll
• Roll format for easy dispensing in field and shop environments

Compatibility

Designed as a general-purpose polyethylene tape suitable for moisture protection, vapor seaming, and surface masking applications across HVAC, plumbing, and construction trades.

Installation Notes

Surface should be clean, dry, and free of dust or oil before application to ensure proper adhesion. No power shutoff is required for tape applications, but follow applicable codes such as IFGC or IPC when using tape in pipe or duct sealing roles. Apply with firm, even pressure along the full length of the bond. Avoid stretching the film excessively during wrap applications, as this can reduce adhesion at the overlap seam.
