KRI maintains a modern manufacturing facility along with knowledgeable, technically-oriented professionals enabling us to consistently meet all of your blueprint specifications and tolerance requirements.

KRI has over forty years experience specializing in the manufacturing of precision molded rubber products. Including fabric reinforced rubber diaphragms and homogenous (all rubber) diaphragms.  By definition, rubber diaphragms are flexible seals that prevent unwanted transmission of substances between two places.  These substances can be liquids, gasses or solutions.  They are characteristically tough and dynamic and essential in many flow control applications.  We provide full production capabilities from prototype and short run quantities through large production runs. KRI takes pride in its ability to consistently produce precision custom rubber diaphragms guaranteed to meet your most stringent requirements and function perfectly within your application.
Fabric Reinforced Rubber Diaphragms

KRI provides a variety of custom molded fabric reinforced rubber diaphragms designed and engineered for specific industry applications, including pneumatic actuators, pumps and control valves.  Our years of experience in the gasket manufacturing industry has proven that certain applications demand that a rubber elastomeric layer must be very flexible and tough in order to withstand repeated flexing over a long lifetime.  It is required that each and every custom molded rubber diaphragm be able to handle mandatory operating temperatures and also be resistant to any chemicals, fluids or gases it may come in contact with.  The construction of fabric reinforced rubber diaphragms is achievable using special reinforcement materials including:

  • Polyester
  • Polyamide (Nylon, High Strength)
  • Cotton
  • High-Temp Polyamide
  • Polymer based fabrics
