DuraVent DirectVent Pro 4x7 36" DVA Concentric Flex Length

Concentric Flex can be used as a cost-effective alternative to 45 degree elbows when offsetting around an obstacle such as a stud, joist, or truss. It allows you to put the vent EXACTLY where you need it, and in a hurry. Aside from speeding up installation, using this approach can also help to minimize the number of joints between pipe sections. Aside from a modest savings on parts, you will also save on installation time.

FULLY COMPATIBLE - DVP Concentric Flex is fully compatible with DirectVent Pro. This gives you the best of both worlds – the robust, long-lasting, professional reputation of our rigid system combined with the infinite convenience of concentric flex when you need it, where you need it.

Direct vent pipes feature a fully unitized twist-lock construction in both 4" x 6 5/8" and 5" x 8" vent sizes. Use of sealant at the joint connections of the inner and outer pipe is optional, unless specified by the appliance manufacturer. To calculate install length, subtract 1 1/2" for each joint. All DirectVent Pro black pipe lengths feature exterior laser-welded seams. No beads or hems, allowing for a beautiful, sleek finish that looks great in any interior.
