Sellerocity 10-Pack of Brass Inserts For Tube Which Measures 5/8" OD X .445" ID, Reinforcement Fittings for Compression Connections, Prevents Tube Collapse 


How to Determine the Right Insert Size – Simply measure your tube’s outer diameter (OD). Compression fitting inserts are sized based on the tubing’s OD, not the insert body that slides inside. For example, a 5/8" OD tube requires 5/8" compression fittings, ferrules, and inserts. The insert’s inner width is 0.445", allowing it to fit inside a 5/8" OD tube, while the outer flange matches the tube’s OD to prevent it from slipping completely inside.

Please see our picture illustration for a visual guide.

Note: the insert's outer flange is roughly the size of the tube OD. 

Reinforces & Prevents Tube Collapse – These 5/8" brass tubing inserts provide internal support to soft tubing, ensuring a secure, leak-free connection in compression fittings.
