3M 7000148368 Polyester Film Tape 4in 36yd Series 396

Product Description

The 3M 7000148368 is a clear polyester film tape from the 3M Series 396 line, designed for demanding holding, reinforcing, sealing, seaming, and splicing applications. The tape measures 4 inches wide and 36 yards long with a total thickness of 4.1 mil. A rubber adhesive backing delivers a tensile strength of 43 lb/in, making it suitable for applications that require a firm, reliable bond. Licensed trade professionals and industrial maintenance technicians reach for this tape when a conformable, temperature-resistant film tape is needed to get the job done right the first time.

Series 396 polyester film tape is used across HVAC, electrical, plumbing, and general industrial service work where holding and sealing integrity matter. The operating temperature range of 40 degrees F to 200 degrees F makes it appropriate for both ambient and moderately elevated temperature environments. Typical applications include seaming insulation facings, splicing film or foil materials, and reinforcing seals in ductwork or piping assemblies. It is stocked in individual rolls for single-use or small-job deployment.

Installation Notes

Apply to clean, dry surfaces free of dust, oil, and loose material to achieve full adhesive contact. Surface temperature should fall within the tape operating range before application. No special tools are required, though a tape dispenser or utility knife aids clean cuts. Follow applicable codes and manufacturer guidelines when using tape as part of a listed assembly.
