FasNSeal Collection 5-1/2" x 25' FasNSeal Double Wall Flex Pipe Length

Use to vent Category II,III and IV gas burning appliances. Listed to UL 1738. Can only be used in vertical or near vertical runs. Custom lengths are available for 3”-12” diameters. Minimum length of 10’ for custom orders. Use with FasNSeal components only.

All FasNSeal single and double wall vent lengths and components feature patented built-in mechanical locking band and triple lipped directional gaskets. All pipes and components are engineered with smooth clean welds located 90° from mechanical locking bands. This construction feature allows for ease of installation. All FasNSeal components which come in contact with exhaust gases and condensates are now silicone free. This important design and manufacturing feature greatly reduces the chances of system breakdown and failure. The main problems with silicone are there are too many adhesion factors which are very difficult to control and the process of binding similar materials with an epoxy, which can weaken the bond over time. Welded seams ensures a leak-free product that is meant to last.
