When your extraction system is turned off a back draft shutter is the perfect way to stop air escaping from your room. It will also prevent unwanted cold / hot air from coming back into the grow room when it is not wanted.  A Back draft shutter is a cylinder shaped piece of equipment with 2 centrally mounted flaps. The air produced by your duct fan will cause these flaps to open, however when the duct fan is turned off the flaps will shut meaning no air can come in from outside.

An Equal Tee is ideal for creating a simple branch on circular spiral ducting. The Equal T-piece has a male connection to fit directly inside circular spiral ducting (secure using recommended fixing methods). If the application requires another spiral fitting (bend, reducer etc) to be connected to the equal tee, a female coupler will be required. Rolled edges for extra strength (also maintains shape).
