Imperial VT0390 Nylon Flex Duct Connector Strap 36 in 50 Pack

Product Description

The Imperial Mfg Group USA Inc VT0390 is a 36-inch nylon flex duct connector strap used to secure flexible ductwork connections in residential and light commercial HVAC systems. This strap cinches around the flex duct collar joint, holding the inner liner, insulation, and outer jacket firmly against the fitting to maintain an airtight seal. Nylon construction resists moisture and moderate heat common to attic and crawlspace installs. Each package contains 50 straps, making it a practical supply for service vans and installation crews who work with flex duct routinely.

This strap is used wherever flexible duct is connected to boots, plenums, collars, or branch fittings in forced-air heating and cooling systems. It is well suited for residential new construction, retrofit installs, and duct repair work. HVAC installers and service technicians use connector straps like the VT0390 as a standard fastening method during duct system assembly. The 36-inch length accommodates a wide range of duct diameters and overlap configurations without requiring cutting on most common flex duct sizes.
