Product Description

Custom Make EPDM Silicone NBR Neoprene Rubber Grommet Dustproof Protective Bushing Sleeve Dust Cover Expansion Bellow

Rubber Bellows, known as rubber expension joints, rubber dust boots, which are used as a cover or expansion joint to protect device or machines against dust, water, oil, grease, acids, bleaches, spatter or other environment elements. 

Rubber bellows are made by rubber compression molding, rubber injection molding or extrusion tool.

 

Why choose us to order rubber bellows?

A. Wall thickness tolerance: less than 0.05mm

B. Mini or less bellow flashing

C. Mold maintenance aiming to up and down mold plate with horizontal stripe in exact position

D. Good ejected molding to improving rubber bellows production efficiency
