5" ID DuraTech


2100 Degree HT 5" DuraTech Chimney System

5" DuraTech Chimney is designed for appliances that are tested and listed for use with a 2100°F HT chimney system, such as wood stoves, fireplaces, furnaces, boilers, stoves, ranges, water heaters, or other appliances fueled by wood, oil, coal, or gas. 5" DuraTech Chimney is tested to UL test procedures 103HT 2100°F and listed under UL re-examination service number MH 7399. 5" DuraTech Chimney is available in stainless steel (SS) outer-casing and stainless steel inner-liner with twist-lock connections.

To calculate installed length of 5" DuraTech chimney, subtract 1 1/4" from each joint overlap of chimney pipe. Important: Allow a minimum of 2-inch air space to combustibles when installing DuraTech chimney.

  • 0.015" 430 stainless steel outer wall.
  • .020" 430 stainless steel inner-liner (25% thicker than competitive chimneys for an extra margin of safety.)
  • Twist-lock end rings provide for ease of assembly.
  • Precision tooled end ring design seals the insulation chamber to prevent water and creosote from soaking into the insulation.


    " M&G DuraVent provides no warranty for the following professional products if such products are not installed by a trained professional installer: DuraTech®, DuraPlus HTC®, DuraChimney® II, PelletVent Pro®, DirectVent Pro®, FasNSeal®, FasNSeal® W2, FasNSeal® Flex, and PolyPro®, and M&G DuraVent's relining products including DuraLiner®, DuraFlex® (SW, Pro, 316, 304), and Ventinox®."
    We feel having a warranty on the products we sell on our site is VERY IMPORANT, so we have dropped DuraTech as our Top Choice. Our Top Choice is now Ventis.
