Cord-ring spools, versatility and quality assured
Cord-ring spools, the best choice
What is a cord-ring?
Cord-ring is an extruded profile of calibrated circular section that is manufactured in the most common O-ring thicknesses. At JIOrings, we have cord-ring spools in stock ranging from 1 mm to 30 mm in bull rope diameter, in different lengths (spools of 5, 10, 25, 50, 100 and 200 metres). As if that were not enough, we also have the possibility of supplying spools with other technical characteristics upon request.
What is the cord-ring used for?
The cord-ring is an excellent solution for the static sealing of lids as it allows to build by seating the O-ring to the exact measurement required for each occasion.
Furthermore, O-rings can also be manufactured by hot vulcanization from the cord-ring. This makes it possible to manufacture virtually any O-ring dimension without the need to invest in an expensive mould for its manufacture. The O-ring made from a cord-ring represents a world of solutions with practically no restrictions. The cord-ring allows for from only one unit (in a multitude of materials, thicknesses and colours) the manufacture of the desired O-ring.

How to use cord-ring
By joining the ends of the extruded cord-ring, you obtain O-rings with different measurements from the standard sizes. The process is simple, you just have to cut the length of the desired circumference and glue the ends together, previously overlapped at 45º. The cord-ring is usually used in cases of static sealing, large flanges or container lids, among other applications.
The cord-ring can be glued cold or warm-vulcanized. O-rings glued cold must respect the thermal and chemical limits of the glue and the characteristics of the elastomer and are used exclusively in static applications. In contrast, vulcanized O-rings can be used in dynamic applications.
The advantages
The advantages of cord-ring make it a highly versatile option:
- Cost savings, because there is no need to manufacture moulds to obtain the desired O-ring from the the cord.
- There are no size limits for large diameters.
- Tolerances can be more accurate than in moulded rings.
- The rings obtained from the cord have no burrs.
- Faster manufacturing.
- Suitable for use with food, pharmaceutical and potable water.

Metres and metres of cord ring in different thicknesses and tolerances
Metres and metres of cord ring
When the universal joint by antonomasia (the O-ring) is not a feasible option, the cord ring may be our best alternative. In many cases in which there is a specific need for maintenance for which there is no standard O-ring, the famous “cut and paste” can get us out of tricky situations.
Here at JIOrings we have more than 50,000 metres of cord ring. It is an O-ring profile cut to the desired measurement and whose two ends stick together either by using cyanoacrylate (better known as Loctite®) which are hot vulcanised. The use of pasted O-rings is usually recommended solely for static applications; whilst vulcanised O-rings can also be assembled in dynamic applications.
From our warehouses we can supply cord ring in different standard materials and thicknesses:
- Thickness: From 1.00 to 20.00
- Tolerance (mm) NBR: ±0.20 to ±0.70
- Tolerance (mm) FPM: -0.10 / +0,30 to -0.60 / +0.80
- Tolerance (mm) EPDM: ±0.30 to ±0.90
- Tolerance (mm) VMQ: ±0.30 to ±0.90
Although on demand we can make cord ring up to 100mm thick and by tenths (e.g. 6.10mm, 6.20mm, 6.30 mm etc.) for those for which the standard does not fit them.
Furthermore, we can’t think of a better time than the month of February with its famous carnavas for presenting this item of our stock: a kit for making O-rings of any diameter, from cord ring which contains different thickness of cord, cutting blade, accessories/support and adhesive. Its use is almost exclusively industrial and is related with maintenance but there are certainly many people involved in making their home-made costume using our cord ring KIT would be just right.
Remember if you need to make an order we guarantee you’ll receive it in 24 hours if you are in the Iberian Peninsula. We are the quickest way to find a seal and if there isn’t one, the cord ring you’ll need to make it.
