ABRA-LINE® Style 404
Expansion Joints for Full Vacuum Abrasive Applications
Style 404 Expansion Joints are specially designed for full vacuum and pressure service in abrasive applications. The tube material is a proprietary urethane formulation. Style 404 can be constructed as a single, multiple, or filled arch design. It can connect pipe flanges in concentric or eccentric tapers to join piping of unequal diameters and connect misaligned piping.
