Rubber Cord & Cord Stock
Continuous-length elastomeric cord supplied by the metre or as bonded/vulcanised custom-diameter O-rings for oversize seals outside standard molded ranges.
Continuous rubber cord stock, coiled for cut-to-length or splicing.
Overview
What it is
Rubber cord is continuous-length elastomer stock supplied by the metre, round in cross-section, for cutting to length and joining on-site rather than molding as a finished ring.
Cord ends are butt-joined and vulcanised (or cyanoacrylate-bonded, for lower-duty use) to form a ring in whatever diameter is needed — useful where a molded O-ring in that exact size doesn't exist, or where only a short production run is justified.
Why use it
Key benefits
- Any diameter without new mold tooling
- Practical for oversize or one-off custom seals
- Field-repairable — a new ring can be spliced on-site
Materials
Which compound, and why
NBR (Nitrile / Buna-N)
General-purpose oil and fuel resistance, the most common cord material.
Applications
Where it's used
Oversize custom gaskets, field-fabricated seals, and low-volume large-diameter O-rings outside standard molded ranges.
