Fabric Reinforced Rubber Diaphragm

Fabric Reinforced Rubber Diaphragm


Fabric reinforced rubber diaphragm are precision molded rubber products having a layer of fabric sandwiched between two layers of rubber. The purpose of this fabric layer is to enhance the durability, tensile strength, flexure strength, flex cycle and many other physical characteristics. We at Western Rubbers India Pvt. Ltd. are rubber diaphragm manufacturer for such critical diaphragms taking utmost care and precision to provide one of the best quality diaphragms at the most competitive cost. Our key products include control valve diaphragm, actuator valve diaphragm and rolling diaphragm.

With our in-house tooling facility, we provide free consultancy for design and development of fabric reinforced rubber diaphragms.
