Nashua 1087646 Foil Duct Tape 3.5 Mil 3 in X 50 Yd

Product Description

The NASHUA 1087646 is an all-weather aluminum foil duct tape engineered for sealing, joining, and patching flexible duct, rigid sheet metal duct, and duct board assemblies. At 3.5 mil total thickness, the tape delivers a durable, moisture-resistant barrier that holds up in both hot and cold conditions. The foil backing conforms to irregular surfaces and maintains adhesion across the temperature swings common in attic, crawlspace, and mechanical room installations. HVAC technicians and sheet metal workers reach for this tape when a permanent, code-acceptable seal is needed on forced-air systems.

This tape is well suited for residential and light commercial HVAC work where duct leakage control is a priority. It applies cleanly to clean, dry duct surfaces and is appropriate for use on supply and return air ductwork, plenums, and duct board seams. The 3-inch width covers standard duct seams in a single pass, and the 50-yard roll provides enough material to handle a full residential duct system or multiple service calls from a single roll.

Key Features

• 3.5 mil total thickness for durability and tear resistance during application
• All-weather formulation maintains adhesion in high-heat, cold, and humid environments
• 3-inch width sized for single-pass coverage of standard duct seams
• 50-yard roll length reduces mid-job roll changes on larger installs
• Aluminum foil backing conforms to sheet metal, flex duct, and duct board surfaces

Compatibility

Designed as an OEM-style sealing solution for use on flexible ductwork, rigid sheet metal duct, and duct board assemblies in residential and light commercial forced-air HVAC systems.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal workers. Power down the air handling unit and allow the duct system to reach ambient temperature before applying tape to ensure proper adhesion. Surfaces must be clean, dry, and free of dust or oil prior to application. Duct sealing practices should conform to local mechanical codes and ASHRAE or SMACNA standards where applicable.
