3M 7000123814 Extra Heavy Duty Duct Tape 48mm 10.7 Mil

Product Description

The 3M 7000123814 is an extra heavy duty duct tape engineered for demanding industrial and mechanical applications. The construction layers polyethylene film over a dense cloth scrim with an aggressive rubber adhesive, delivering strong adhesion, abrasion resistance, and moisture resistance in a single roll. At 10.7 mils thick, the tape provides a durable barrier suitable for sealing, bundling, and patching tasks where standard duct tapes fall short. It tears cleanly by hand without tools, and tack-free edges keep the roll manageable on the job. Individual roll wrap protects each unit during storage and transport, reducing waste and preserving adhesive integrity until use.

This tape is suited for HVAC contractors, industrial maintenance technicians, and trade professionals working in environments that require a high-performance, moisture-resistant tape. The olive color and industrial-grade backing make it a practical choice for ductwork sealing, equipment repairs, and general fabrication tasks in both commercial and light industrial settings. Each roll measures 48mm wide by 54.8 meters long, providing extended run length per roll for large jobs.

Key Features

• 10.7 mil total thickness for heavy duty durability and puncture resistance
• Rubber adhesive bonds aggressively to most surfaces with 61 oz per inch width adhesion to steel
• Tensile strength of 32 lbs per inch width resists tearing under load
• Polyethylene film over dense cloth scrim construction provides abrasion and moisture resistance
• Easy hand-tear design with tack-free edges for controlled handling on the job
• Individual roll wrap preserves adhesive integrity and reduces waste in storage

Compatibility

Designed for demanding duct tape applications in HVAC, industrial maintenance, and general construction environments where high adhesion, moisture resistance, and abrasion resistance are required.

Installation Notes

This tape is applied by hand and requires no special tools; surface preparation with a clean, dry substrate improves bond strength. For HVAC duct sealing applications, verify that the tape meets local mechanical code requirements, as some jurisdictions require UL 181-listed products for specific duct system types. Avoid applying at temperatures outside the rated use range, and allow adequate dwell time for the adhesive to develop full bond strength before the assembly is put into service.
