3M 7000049205 Glass Cloth Tape 398FR White 4in X 36yd

Product Description

The 3M 7000049205 is a white glass cloth tape with an acrylic adhesive, engineered for applications that demand high adhesion, flame retardant performance, and an abrasion-resistant backing. Sold as the 398FR series, this tape meets the flame retardancy requirements of F.A.R. (Federal Aviation Regulations), making it a reliable choice for aircraft maintenance and repair work. The glass cloth construction provides dimensional stability and durability under mechanical stress, while the acrylic adhesive delivers strong, long-lasting bond strength across a range of surfaces. Each roll measures 4 inches wide by 36 yards and weighs 5.37 pounds.

This tape is used in aerospace maintenance, industrial sealing, and repair applications where flame retardant properties are required by code or specification. Its abrasion-resistant backing makes it suited for areas subject to wear or contact with irregular surfaces. Technicians in aviation MRO, industrial maintenance, and facilities work install this tape for sealing, bundling, and surface protection tasks where a standard cloth tape would not meet flame retardancy standards.

Key Features

• Meets F.A.R. flame retardancy requirements for aircraft maintenance and repair
• Acrylic adhesive provides high adhesion to a variety of surfaces
• Glass cloth backing resists abrasion and provides dimensional stability
• White finish for clean, visible application identification
• 4-inch width suited for sealing and covering broader surface areas

Compatibility

Designed for use in aerospace, industrial, and facilities maintenance applications requiring flame retardant sealing tape that meets F.A.R. flame retardancy standards.

Installation Notes

This tape is applied by hand or with a tape dispenser; no special tools are required for most installations. Ensure the application surface is clean, dry, and free of oils or loose debris before applying to achieve full adhesive contact. In regulated environments such as aircraft maintenance, verify that the tape specification meets the applicable airworthiness directive or maintenance manual requirement before installation. Follow all facility and regulatory protocols for flammable material handling during storage and use.
