Polycord, also referred to as urethane or polyurethane cord, is the standard material in producing polyurethane belts and O-rings. It can be used to make line shaft O-rings, roller-to-roller O-rings, divert O-rings, and much more.
Polycord comes in spools of various diameters (1/8”, 3/16”, 1/4”, 5/16”, and 3/8”), durometers ranging from 80A-95A, textures (standard, orange, rough green, high tension, reinforced), and colors, which is then cut to the necessary length.
See below for common uses of each texture:
- Standard: for most standard activities
- Orange: for divert applications when transferring boxes between conveyors (85A)
- Rough Green: for lightweight handling (88A, 90A)
- High-Tension: for heavyweight items. Comes is various colors (blue, red, green) based on maximum weight (88A)
There are many pros and cons to using polycord versus prewelded(endless) poly O-rings.

Cons |
| No tearing down machine | Downtime |
| Cheaper | Must purchase welding tool/kit |
| May be easier to apply | More manual labor |
| Ability to create new sizing yourself | Higher error potential |
Before placing your polycord order, you will need to know your durometer, diameter, cut length, texture, and color (usually clear).
