3M 7000050121 Ptfe Film Tape 5490 Gray 3/4in X 36yd

Product Description

The 3M 7000050121 is a PTFE extruded film tape supplied in gray, measuring 0.75 inches wide by 36 yards long at a 3.5 mil thickness. It uses a silicone adhesive backing that bonds to a wide range of surfaces and holds up under chemical exposure. The PTFE film face delivers an exceptionally low-friction, slick surface, making this tape suitable for sealing, masking, and slide applications in industrial and trade environments. Licensed tradespeople and MRO technicians working with equipment that requires chemical-resistant or non-stick surface protection are the primary installers. The roll format and controlled unwind design resist curling during application, keeping workflow clean and consistent.

This tape is used in applications that demand a chemically resistant, non-stick surface interface. Common use cases include masking during chemical processing, sealing threaded fittings or flanges exposed to aggressive fluids, and protecting surfaces from adhesion or abrasion. It performs in both light industrial and heavy-duty commercial environments where PTFE film properties are required. The silicone adhesive system allows use across a broad temperature range, making it appropriate for HVAC, plumbing, and general mechanical assemblies where conventional tapes would degrade.

Key Features

• PTFE extruded film face provides a low-friction, non-stick surface for sealing and masking applications
• Silicone adhesive offers strong bonding and chemical resistance across a wide temperature range
• 3.5 mil total thickness balances conformability with durability
• Resists curling during unwind for consistent, clean application
• Chemical-resistant construction suitable for contact with aggressive fluids and process chemicals
• Roll format with 36-yard length reduces change-outs on high-volume jobs

Compatibility

Designed as an OEM-style general-purpose PTFE film tape for industrial sealing, masking, and surface-protection applications across HVAC, plumbing, and mechanical service contexts.

Installation Notes

This tape is applied by hand and requires no special tools beyond a clean, dry substrate. Ensure the application surface is free of dust, oil, and moisture before applying to achieve full adhesive contact. When used for chemical sealing or masking, confirm the tape overlaps all exposed surfaces to prevent bleed-through. Follow applicable site safety procedures when working near chemicals or pressurized systems.
