Product Description

Customized Inflatable Neoprene Nitrile EDPM Silicone Rubber Expansion Joint 

Rubber Expansion Joint is used as a cover or expansion joint to protect 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.

Rubber Bellows Design Guide

Rubber Bellows Some Typical Applications
Expansion joints
Rod & Ball screw covers
Piping penetration seals
Fan duct connections
Compressor and engine intake and exhaust manifold connections
Different Silicone Rubber Bellows durometer demands, surface demands, parting lines demands or rubber flashing demands have different production difficulty and production cost. Epecially for mold-making technology demands, compression mold steel choice, mold maintain when mass production etc.
