Key features

• •[Size & Package]: The package includes 1 piece of 1 Meters / 3.28 Feet of high-temperature resistant filament feeder tube. The tube has a 5mm inner diameter and a 7mm outer diameter, with the optimal inner diameter size designed to minimize "wiggle room" or flex.
• •Material - The tube hose is made of plastic with good wear resistance and high temperature resistance, ensuring reliable filament feeding and consistent printing results in daily printing environments. The flexible tube is bendable but not easy to deform, providing long-lasting performance for your 3D printing projects.
• •Stable Filament Feeding & Precise Transmission - The tube adopts ultra-smooth oil-free lubrication material to reduce filament circulation friction, allowing filament to pass through the extruder to the hot end more smoothly, thereby reducing the risk of blockage and the failure rate, achieving stable filament feeding and precise transmission.
• •Easy to Use: Select the appropriate size based on the inner diameter (ID) and outer diameter (OD), cut vertically with the cutter(not included) to ensure a smooth cut, and then use a quick-connect pneumatic fitting(not included) to connect the hose to the device or pipeline. Perform a pressure test before use to ensure there is no leakage.
• •Wide Application - In addition to being used in 3D printers, the tubes are also widely used in laboratory equipment conduits, guide rails, gas and liquid conveying tubing, electrical insulation at various frequencies, lining pipes, heat exchanger tubing, as well as machinery, electronics, valves, and other uses.
