Pipe-to-Pipe Connections are made by using a fitting size coupling that slips inside the mating pipe sections. A stop bead runs around the middle of the coupling to center the coupling in the connection. Secure the connection by installing sheet metal screws through the outer shell of the duct, 1/2 inch from the bead.

Connectors is sizes 6”- 24” (even sizes only) are fabbed utilizing the complete seal system. Complete Seal fittings are manufactured from galvanized steel meeting spec AST M A-653 (Lock forming Quality). They feature a double legged E P DM gasket which creates a virtually airtight connection when slipped into spiral pipe. The gasket is mechanically attached to the fitting with a 180 degree hemmed edge. This hem gives added rigidity to the fittings, ensures that the gasket will never slip out of place and makes a safe rounded edge for the installer.
