The EDGE ® System 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 a highly efficient duct system and also great for exposed systems.
The EDGE ® Product Features
FEATURES
All fittings will have a factory installed EPDM gasket, which has an operating temperature rating of -20°F to 212°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 green EPDM hollow seal that will act as the sealing section.
The gasket is attached to the fitting with a 180° 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 SMACNA standards.
The EDGE® System allows for substantial space for insertion of the screws, because the gasket is located on the leading EDGE of the fitting. (NOTE: The use of sheet metal screws with a rubber gasket would insure that all screw holes are sealed as well.)
The EDGE® System has been tested in accordance to SMACNA's Air Duct Leakage Test Manual and meets SMACNA Class 3 leakage standards
