3M 7000123454 Vent Tape 394 White 1.5 in X 36 Yd 4.0 Mil

Product Description

The 3M 7000123454 is a 4.0 mil vent tape featuring a non-woven, synthetic backing coated with an acrylic adhesive. The porous non-woven construction allows high air and gas permeability while still acting as a solids barrier, which reduces voids and minimizes cleanup after application. The roll measures 1.5 inches wide by 36 yards long, making it suitable for extended runs without frequent roll changes. This tape is intended for use by tradespeople and industrial technicians who need a reliable, flexible tape for sealing, holding, or reinforcing tasks in demanding environments.

This vent tape is used across a wide range of industrial and trade applications including sealing ductwork and enclosures, holding components in place during assembly, reinforcing joints, masking surfaces, protecting materials during processing, and splicing sheet goods or films. Its porous backing makes it particularly well-suited for applications where trapped air or gas must be allowed to escape while the adhesive maintains a firm bond on the substrate surface.

Key Features

• 4.0 mil total thickness for durable, flexible coverage
• Non-woven synthetic backing with high air and gas permeability
• Acrylic adhesive provides reliable bond across sealing and holding applications
• Solids barrier construction minimizes voids and reduces post-application cleanup
• Good burst strength for reinforcing and splicing tasks
• 1.5-inch width and 36-yard length per roll for extended application runs

Compatibility

Designed for general industrial and trade use including sealing, holding, reinforcing, identifying, masking, protection, and splicing applications across a variety of substrates and surfaces.

Installation Notes

Surface should be clean, dry, and free of oils or loose debris before applying the tape to ensure proper adhesion. Apply firm, even pressure across the full width of the tape after placement to activate the acrylic adhesive. When used in HVAC or ductwork sealing applications, follow applicable local codes and manufacturer guidelines for allowable tape types. Avoid stretching the tape during application, as this can reduce effective bond area and long-term adhesion performance.
