Rubber Duct Expansion Joints

Our Rubber Duct Expansion Joint is made for air and vent systems. We use it in commercial buildings, factories, power stations, and subway vents. We have been making pipe parts for over 20 years. This rubber duct expansion joint stops air leaks, cuts vibration, and resists aging. It makes your vent system more stable. We use EPDM or neoprene rubber with a high-strength fiber composite. We use one-piece vulcanization to make it tough and tear-resistant. The flanges are galvanized, carbon steel, or stainless steel.

This thing works from -30℃ to 150℃. It handles air pressure up to ±5000Pa. Each rubber duct expansion joint gets a static pressure test at 1.5 times the design pressure. It takes in three-directional duct movement and stops duct stress. It stops the duct from bending or tearing. It lowers duct noise and equipment noise. The flexible shape fits complex duct runs. It is easy to put in and line up. It has good air tightness with no leaks. The inside wall is smooth with low resistance. Our standard sizes are in stock. We give a 24-month warranty.
