Rubber Connection Coupling for GM System

This connection coupling (fitting) is designed for the airtight joining of flexible corrugated ventilation ducts to each other or for connecting them directly to the GM system distribution manifolds. Using this element ensures the integrity of the ventilation route, preventing air leaks and pressure drops.

The part is made of dense, elastic rubber and features a specially designed ribbed inner surface. Unlike rigid plastic alternatives, the elastic material gently wraps around the corrugation without crushing it, while the ribs act as multiple sealing contours.

• Damage-free reusability: the flexible rubber does not break or crush the plastic ribs of the pipe during installation. If you need to reassemble the joint or adjust the route, you will not have to cut off a damaged section of the duct.
• Clean push-fit installation: the ribbed design allows the duct to be securely fixed using a simple push-fit method. This guarantees a high class of airtightness without the need to wrap joints with aluminum tape or apply silicone sealants.
• Acoustic comfort: the elastic rubber body acts as a vibration isolator. It dampens structural noise from the airflow, preventing it from being transmitted through the rigid elements of the ventilation network.
• Versatility: the coupling is available in standard diameters of 63 mm, 75 mm, and 90 mm, perfectly matching the parameters of GM system ducts.
