315mm Male Duct Coupling

315mm Male Duct Coupling

A 315mm (12") male coupling connector for joining two pieces of ductwork together — also works with hose clips to join flexible ducting runs. Essential when your fan, filter, and ducting all end in female flanges and you need to bridge them.

Why growers need duct couplings:

• Joins two female duct ends together — fan to filter, duct to duct, anywhere you need a bridging piece
• 315mm (12") — pro-grade commercial size, pairs with 12" fans and filters
• Works with hose clips — secure flexible ducting over the coupling, clamp down
• Simple and reliable — no moving parts, no failure modes

Who it's not for:

Match to your duct diameter — for 8" ducting use the 200mm coupling, for 10" use the 250mm. Wrong-size couplings won't fit. For rigid galvanised ductwork, you'll need different fittings.
