3M 7000142887 Ptfe Film Tape 5490 Gray 2in X 36yd

Product Description

The 3M 7000142887 is a PTFE extruded film tape sold under the 3M 5490 product line. The tape consists of a 3.7 mil gray PTFE extruded film carrier bonded to a silicone adhesive backing. It delivers an exceptionally slick, low-friction surface once applied and resists curling during unwind — a practical advantage in high-volume or repetitive application work. The silicone adhesive provides reliable adhesion across a wide temperature range, making this tape suitable for sealing, masking, and surface-protection tasks where chemical resistance is required. This roll measures 2 inches wide by 36 yards long and weighs approximately 0.69 pounds.

This tape is used in industrial, HVAC, plumbing, and electrical trade applications where a chemically resistant, non-stick surface is needed. Common use cases include sealing threaded fittings, masking surfaces during high-temperature processes, lining chutes or guides to reduce friction, and protecting components from chemical exposure. It is handled by HVAC technicians, pipefitters, electricians, and industrial maintenance professionals. The tape's resistance to curling during unwind supports clean, consistent application on both flat and irregular surfaces.

Key Features

• 3.7 mil PTFE extruded film construction for a durable, low-friction surface
• Silicone adhesive backing provides high-temperature and chemical resistance
• Resists curling during unwind for clean, controlled application
• Gray color supports use in masking and sealing applications where visibility matters
• 2 inches wide by 36 yards long per roll — suitable for mid-scale jobs and frequent use

Compatibility

Designed as an OEM-style tape product for industrial, HVAC, plumbing, and electrical trade sealing and masking applications requiring a chemically resistant PTFE film surface.

Installation Notes

Application requires a clean, dry surface free of oils, dust, and loose material for proper adhesion. Ensure power is off and any pressurized lines are depressurized before applying tape to fittings or mechanical components. A roller or firm hand pressure helps seat the silicone adhesive and eliminate air pockets. Follow applicable codes such as the IFGC or IPC when using tape in gas or plumbing line service applications.
