2 The EDGE TM Features, Benefits & Construction 2 The EDGE TM ystem will eliminate the sealing of all connections in your spiral pipe system. This system will not only provide a labor savings for the installer, it is also great for exposed systems. FETURE ll fittings will have a factory installed EPDM gasket, which has an operating temperature rating of -20 o F to 212 o F. The smoke and flame spread rating is 0/0. The gasket construction is of a black EPDM base with a wiper for machine application and a gray EPDM hollow seal that will act as the sealing section. The gasket is attached to the fitting with a 180 o hemmed edge that will hold the gasket in place, as shown in the diagrams to the right. The connections are secured with self-tapping sheet metal screws per MCN standards. The EDGE TM ystem allows for substantial space for insertion of the screws, because the gasket is located on the leading EDGE of the fitting. The EDGE TM ystem has been tested in accordance to MCN's ir Duct eakage Test Manual (1st Edition , printing #7-2003) and meets MCN Class 3 leakage standards.
