3M 7000048701 Ptfe Film Tape 5491 Gray 14in X 36yd

Product Description

The 3M 7000048701 is a PTFE extruded film tape with a silicone adhesive backing, sold under the 3M 5491 product family in gray. At 6.7 mil total thickness, this tape delivers an exceptionally slick, low-friction surface upon application. The PTFE film construction resists curling during unwind, making it easier to handle and apply in demanding shop and field conditions. It is designed for use in sealing, masking, and surface-protection applications where chemical resistance and release properties are required. Licensed trade professionals and industrial maintenance technicians are the primary installers.

This tape is suited for applications where a durable, chemically resistant surface is needed — including masking during coating or painting processes, sealing joints exposed to aggressive chemicals, and providing a slip surface on guides, chutes, or tooling. The 14-inch width and 36-yard length make this roll practical for wider coverage in industrial or commercial settings. It is a thicker alternative to the 3M 5490 tape, offering added durability where a heavier mil gauge is required.

Key Features

• 6.7 mil PTFE extruded film construction provides a low-friction, non-stick surface
• Silicone adhesive backing for reliable adhesion across a wide temperature range
• Resists curling during unwind for cleaner, faster application
• Chemical resistant surface suitable for sealing and masking in harsh environments
• Thicker profile compared to 3M 5490, offering enhanced durability
• 14-inch width x 36-yard length per roll for broad coverage

Compatibility

Designed as an OEM-style replacement and general-use PTFE film tape suitable for industrial sealing, masking, and surface-protection applications across a range of commercial and industrial equipment and surfaces.

Installation Notes

Surface preparation is critical — clean and dry the substrate thoroughly before applying the tape to ensure full adhesive contact. Apply firm, even pressure across the tape width using a roller or squeegee to eliminate air pockets and promote adhesion. When trimming, use a sharp utility knife or scissors rated for film tapes to avoid tearing the PTFE film. Follow applicable safety protocols when working near chemical exposure environments.
