Black 2mm round sponge cord coiled on a wood surface, supplied as a 1m seal length

2mm Diameter Sponge Cord

$0.99
1

2mm sponge cord for small seals, gaskets, and printer-filter builds. This is a flexible black round sponge cord supplied as a 1 meter length for places where a printed part, lid, or enclosure mod calls for a narrow compressible seal.

Why use sponge cord instead of flat foam tape?

  • Round 2mm profile compresses into grooves and tight printed channels better than wide adhesive foam.
  • Cut-to-fit length lets you trim only what the part needs and save the rest for small seals.
  • Useful around air-filter projects where reducing bypass and rattles matters more than a hard mechanical joint.

Specifications

  • Diameter: 2mm
  • Length supplied: 1m
  • Shape: round sponge cord
  • Color: black

Fitment notes

  • Use this only where your BOM or printed part calls for 2mm cord.
  • Nevermore StealthMax documentation calls for 3mm sponge cord on the main chamber, so this is not a drop-in StealthMax main-chamber seal unless your specific mod says 2mm.
  • For filter-media refills, see Decent Filter Food Obsidian - 1kg. For a compact complete filter kit, see the Zero-Filter Kit by Zruncho.

What it is not

  • Not adhesive-backed foam tape.
  • Not a 3mm gasket cord.
  • Material formulation and country of origin are not marked on the product photo; do not use where a certified rubber compound is required.
