3M 7000048566 Vent Tape 394 White 2in X 36yd 4.0 Mil

Product Description

The 3M 7000048566 is a 4.0 mil vent tape featuring a non-woven, porous synthetic backing coated with an acrylic adhesive. The porous backing provides high air and gas permeability, which allows gases to escape during certain sealing operations while the tape still acts as a solids barrier. Each roll measures 2 inches wide by 36 yards long. The result is minimal voids in the bonded area and easier cleanup compared to non-porous alternatives. HVAC technicians, sheet metal workers, and industrial maintenance professionals use this tape where both adhesion and controlled venting are required.

This tape is suited for a range of industrial and HVAC applications including sealing, holding, reinforcing, identifying, masking, surface protection, and splicing. Its combination of good burst strength and a solids-blocking, air-permeable backing makes it a practical choice in situations where trapped gases or air pockets would otherwise compromise a seal or create defects during assembly and bonding operations.

Key Features

• 4.0 mil (0.10 mm) total thickness for a durable, conformable profile
• Non-woven porous synthetic backing with high air and gas permeability
• Acrylic adhesive provides reliable bonding across a range of surfaces
• Acts as a solids barrier while allowing gas passage to minimize voids
• Good burst strength for demanding sealing and reinforcing applications
• Suitable for sealing, masking, reinforcing, splicing, and identification tasks

Compatibility

Designed for general industrial and HVAC trade applications where a venting, non-woven tape is required for sealing, holding, or splicing operations.

Installation Notes

This tape is applied by hand and requires no special tools beyond a tape dispenser or knife for cutting. Ensure the application surface is clean, dry, and free of oils or loose debris before applying for best adhesion. When used in HVAC or industrial environments, follow applicable codes and manufacturer guidelines for the specific assembly or sealing task. Do not use as a primary structural fastener or as a substitute for code-required sealing materials where such requirements apply.
