Characteristics of Quality a Duct Connector

Because connectors tie your duct system together, the small piece is a major factor in controlling the temperature of your cannabis garden. To make sure the air hose stays in its place for a long time, here are some things to keep in mind when buying a connector:

  • Sizes much like hoses, not all connectors will fit easily with any duct system. You need to be aware of the sizes of the hose and the connectors to create an airtight seal.
  • The material you need to keep in mind that hot air and moisture will constantly pass through your connectors at all times. You want a material that can handle high temperatures and corrosion such as galvanized steel. While you do not have to worry about plastic materials experiencing any rust, you need one that can handle the heat.


The Lint Connector is our pick for the best duct connector out of the 10. This connector lets you disconnect the hose without using any tool. Cleaning your air system or reconfiguring its layout is easy thanks to this feature.

In addition to its connectable feature, the Lint Connector’s plastic material is not susceptible to rust or corrosion. You can also remove the lint from the hoses more easily with this feature. A collection of lint in the ducting can be a fire hazard if let alone for a long time.
