CRDF Series - Silicone Foam Cord

CRDF: Silicone Foam Cord

  • Compresses to Seal Off Slots and Through Holes
  • Conforms to Irregularly Shaped Openings
  • Cut to Size
  • Color Coded for Easy Identification


Our Solid Silicone Foam Cord (CRDF) product line is a great solution when looking for a compressible part to fit into a threaded or non-threaded opening. The solid silicone foam cord is so flexible that it can often be used to plug irregularly shaped openings. CRDF Cord is a closed-cell foam structure and will not absorb liquid.


Powder Coating, E-Coating, Plating and Anodizing


Used to create a liquid tight seal in threaded and non-threaded slots, grooves, and through holes.


  • Elongate the cord during application to make insertion easy. Cord will return back to original shape when released and create a liquid tight seal.
  • To ensure a liquid tight seal, pick a product whose outer diameter (OD) dimension is at least 3-10% larger than the hole or groove that is being masked.
