Rubber Sleeve and Flex Connector Fabrications

We can quickly supply Straight or Tapered (Conical) Flex Connectors to any material handling manufacturer or distribution facility in the U.S.


Our Rubber Sleeve Fabrication is the best in the industry.

  • Some rubber fabricators rely on a cold-bond adhesive process  a shortcut that creates weak, brittle joints which are prone to tearing.
  • We use uncured compounds in our splicing techniques for all types of sleeve manufacturing.
  • We hot vulcanize seams with heat and pressure for durability and reliability.
  • Each sleeve is carefully inspected to verify adherence to your required specs and our commitment to deliver high quality products.

Contact us with your rubber sleeve, rubber boot or rubber tube needs. Youll get competitive pricing on high quality products made to exacting specifications.
