3M 7000123895 Glass Cloth Tape 3 Inches X 36 Yd 7.0 Mil

Product Description

The 3M 7000123895 is a general purpose glass cloth tape designed for applications that demand high-temperature resistance and strong adhesion. The tape features a 6.5 mil glass cloth backing coated with a silicone adhesive, delivering excellent tensile strength and abrasion resistance. At 7.0 mil total thickness, it handles demanding thermal environments where standard tapes fail. Supplied in white, it is used by HVAC technicians, electricians, and industrial maintenance professionals who need a durable, conformable tape that stays bonded under heat stress.

This tape is suited for high-temperature masking, bundling, and insulation wrap in residential and commercial HVAC systems, electrical panels, and industrial equipment. Each roll measures 3 inches wide by 36 yards long, providing enough material for a range of job-site tasks. The silicone adhesive maintains its hold across a wide temperature range, making it appropriate for duct wrap, motor lead insulation, and heat shielding applications where conventional pressure-sensitive tapes would soften or fail.

Key Features

• Silicone adhesive provides strong, high-temperature bonding on demanding surfaces
• Glass cloth backing offers excellent tensile strength and abrasion resistance
• 7.0 mil total tape thickness for added durability in harsh environments
• 3 inches x 36 yd roll size suits a wide range of HVAC and electrical wrap applications
• White finish for clean, professional appearance on visible installations
• Easy unwind construction reduces hand fatigue during repetitive taping tasks

Compatibility

Designed as a general purpose glass cloth tape suitable for high-temperature masking, insulation, and bundling tasks in HVAC, electrical, and industrial maintenance applications.

Installation Notes

Apply to clean, dry surfaces free of dust, oil, and loose material for best adhesion. Ensure power is off and equipment is de-energized before applying tape near electrical components or motor leads. Follow applicable NEC and local codes when using tape as part of an electrical insulation assembly. Avoid stretching the tape excessively during application to maintain backing integrity and consistent adhesion.
