3M 7000048721 Ptfe Film Tape 5490 Gray 12in X 36yd

Product Description

The 3M 7000048721 is a PTFE extruded film tape in the 3M 5490 series, supplied in gray with a silicone adhesive backing. At 3.7 mil thick, the tape delivers an exceptionally slick, low-friction surface once applied. The silicone adhesive resists high temperatures and bonds reliably to a range of substrates without leaving residue. The extruded PTFE film construction resists curling during unwind, which speeds up application in the field. HVAC technicians, plumbers, and industrial maintenance professionals use this tape for chemical-resistant sealing and masking tasks where standard films would degrade.

This tape is suited for applications requiring a chemically inert, low-friction barrier. Typical uses include masking during chemical processing, sealing surfaces exposed to aggressive fluids or solvents, and providing a slip layer between moving mechanical components. The 12-inch width and 36-yard length per roll make it practical for both wide-area masking and repetitive sealing tasks in light commercial and industrial maintenance settings. It is sold by the roll with a minimum order quantity of 2 rolls.

Key Features

• 3.7 mil PTFE extruded film construction resists tearing and chemical attack
• Silicone adhesive withstands high-temperature and chemically aggressive environments
• Exceptionally low-friction surface reduces drag on mating components
• Resists curling during unwind for faster, cleaner application
• Gray color aids visual identification in masking and sealing workflows
• 12-inch width suits wide-area coverage without seaming

Compatibility

Designed as an OEM-style utility tape for sealing, masking, and slip-layer applications where a chemically resistant PTFE film with silicone adhesive is required.

Installation Notes

Surface should be clean, dry, and free of oils or loose material before application. Apply firm, even pressure across the full tape width to ensure full adhesive contact. When using as a chemical masking barrier, verify solvent compatibility with both the PTFE film and the silicone adhesive before committing to the application. No special tools are required, but a roller or squeegee improves bond consistency on large surfaces.
