Parker Offers Improved Splicing Capability for Solid and Hollow Profile Seals

Darcoid works with Parker’s JBL Division precision extrusion and spliced products offer an ideal, cost-effective sealing solution for many applications. These include low-closure force seals, large diameter profiles that cannot be molded, hollow cross-section cord or requirements for non-standard O-rings and other extruded profiles with an inside diameter larger than 2.500 inches.

Product Capability: The JBL Division’s splicing and fabrication capabilities continue to expand:

Size Capability

  • Cross-sections: .040” to 1.00
  • Spliced I.D.'s 2.500” and larger


  • Silicone
  • Fluorosilicone
  • EDPM
  • Fluorocarbon
  • Nitrile

Durometer’s range from 40 to 90 Shore A

Profile Cross-Sections

Darcoid offers an almost unlimited variation of cross-section profiles. Shown above are only a few of the more common extruded profile configurations currently available.

Markets and Potential Applications

  • Outdoor Electronics & Communications Enclosures
  • Electronic Equipment Transit Cases

Handheld Electronics & Communication Devices

  • Semiconductor Applications
  • Power Generation Plants
  • Low-closure Force Sealing Requirements
  • Automotive Applications
  • Non-Standard O-rings & Hollow O-rings with I.D.’s greater than 2.500

Features and Advantages of Spliced Products

  1. Superior hot vulcanization capability (High bond integrity).
  2. No tooling required for standard O.D. / I.D. combinations.
  3. Exclusive use of quality, sealing-grade materials.
  4. Ease of adjusting closure force by adjustment of cross-section design, C/S I.D. or durometer.
  5. Hollow cross-sections are excellent replacements for foam or sponge gaskets, offering superior compression set resistance.
  6. Interference-fit designs with asymmetrical solid or hollow cross-sections for ease of assembly in seal grooves without adhesives or mechanical retainers.
  7. Low-cost option for static face or radial face seal O-rings over 2.500” I.D.
  8. Can be used in non-standard grooves.
