Mestek Machinery’s Hot Melt Sealant System is a sealing system for transverse duct seam by works by heating a temperature activated sealant and inserting to the Pittsburgh lock roll former so that it produces a Pittsburgh seam that is airtight. It can be used on a standalone machine or on a coil line to meet [SMACNA duct construction standards](https://www.smacna.org/store/browse-by-topic/industrial-duct-construction-standards). ![Hot Melt System Machine](https://blog.mestekmachinery.com/hs-fs/hubfs/Imported_Blog_Media/LKF_Hot-Melt-System-Machine-260x300-3.jpg?width=155&height=179&name=LKF_Hot-Melt-System-Machine-260x300-3.jpg) The Hot Melt Sealant System is a perfect accessory for our [Engel 800P](https://www.formtektemp.com/mestekmachinery/mestek-machinery-ahr-2018-engel-800p-rollformer). While the Pittsburgh lock is being roll formed, the sealant is injected the formed material to make the seam airtight. Unlike a cold sealant system, the Hot Melt Sealant System has less loss of sealant due to overfilling the seam and the sealant is stored in a solid state, whereas cold sealant is scrapped when it hardens.
