3M 7010374386 Ptfe Film Tape 5491 Gray 14in X 72yd

Product Description

The 3M 7010374386 is a PTFE extruded film tape supplied in a 14-inch-wide by 72-yard roll. It uses a silicone adhesive backing bonded to a gray PTFE film, producing an exceptionally low-friction surface on contact. The tape is a thicker-construction version of 3M Tape 5490, offering added durability where a heavier film is required. It resists curling during unwind, which keeps application clean and consistent. The silicone adhesive holds reliably across a wide temperature range. Installers in industrial, HVAC, and mechanical trades use this tape for sealing, masking, and surface-protection applications where chemical resistance is a priority.

This tape is suited for applications that demand a chemically resistant, non-stick surface layer. Common uses include lining chutes, slides, and guides where friction reduction is needed, as well as masking surfaces during high-temperature processes. It is also used in HVAC and mechanical work for sealing and insulating applications where standard film tapes lack adequate thickness or chemical resistance. The roll format suits both bench work and field installation.

Key Features

• PTFE extruded film construction delivers an exceptionally low-friction, non-stick surface
• Thicker film profile compared to 3M Tape 5490, providing added mechanical durability
• Silicone adhesive backing offers strong adhesion across a wide temperature range
• Chemically resistant surface suitable for sealing and masking in demanding environments
• Resists curling during unwind for cleaner, more consistent application
• Large-format roll — 14 inches wide by 72 yards — reduces changeover frequency on the job

Compatibility

Designed as a direct upgrade or thicker-profile alternative to 3M Tape 5490, suitable for industrial sealing, masking, and friction-reduction applications requiring a PTFE film with silicone adhesive.

Installation Notes

Surface should be clean, dry, and free of oils or contaminants before tape application to ensure proper adhesion. Apply with firm, even pressure across the full width to eliminate air pockets and ensure full contact with the substrate. When cutting, use a straight edge and a sharp utility knife or tape dispenser to avoid fraying the PTFE film. No special tools or fasteners are required, but gloves are recommended when handling large rolls to avoid contaminating the adhesive.
