3M 7000048695 Ptfe Film Tape 5491 Gray 4in X 36yd

Product Description

The 3M 7000048695 is a gray PTFE extruded film tape sold under the 3M 5491 product line. It is constructed from a 6.7 mil PTFE extruded film backing with a silicone adhesive system. The result is an exceptionally slick, low-friction surface that resists chemical attack and holds up under high-temperature conditions. This tape is a thicker-gauge version of the 3M 5490 series, offering added durability for demanding sealing and masking applications. HVAC technicians, industrial maintenance professionals, and plumbers install this tape where a chemically resistant, non-stick surface is required in harsh operating environments.

This tape is suited for sealing, masking, and lining applications in industrial, HVAC, and plumbing settings where exposure to chemicals, solvents, or elevated temperatures is expected. The silicone adhesive provides reliable bonding while the PTFE film face resists adhesion from most substances, making it practical for use as a release liner, a slide surface, or a protective mask over metal or plastic components during processing or installation. Each roll measures 4 inches wide by 36 yards long.

Key Features

• 6.7 mil PTFE extruded film construction for added thickness and durability
• Silicone adhesive bonds to a wide range of substrates
• Exceptionally slick PTFE surface reduces friction on contact areas
• Resists curling during unwind for cleaner, faster application
• Chemical-resistant film face suitable for masking and sealing in corrosive environments
• Gray color for easy identification on installed surfaces

Compatibility

Designed as a thicker OEM-style alternative to 3M PTFE Film Tape 5490, suitable for sealing, masking, and low-friction lining applications across industrial, HVAC, and plumbing trades.

Installation Notes

This tape is typically applied by hand or with a tape applicator tool on clean, dry surfaces free of oil, dust, and loose particles. Power down or isolate any equipment before applying tape to moving or energized components. Avoid stretching the film during application to maintain uniform thickness and adhesion. Ensure surface temperatures are within the adhesive operating range before committing to the final installation.
