Silicone Rubber Bellows are used as a cover or expansion joint to protect device or machines to protect against dust, water, oil, grease, acids, bleaches, spatter or other environment elements. Silicone rubber bellow hose is a typical cover and connector, which is made by rubber compression molding, injection molding.

Silicone Bellow Hose

Silicone Bellow Hose, also called as Silicone Vacuum Bellow Seal, Flexible Silicone Bellow, are used as a cover or expansion joint or connector to protect and connect device or machines, which are made by rubber compression molding, rubber injection mold or extrusion tool.

Rubber Bellows are designed as a cover mainly protect against dust, water, oil, grease, acids, bleaches, spatter or other environment elements.

Silicone Rubber Bellow can have different kinds of shapes, materials, colors, hardeness according to the usage in different areas.
