One of our oldest and most popular products is the Hot Vulcanised Cord ring (‘Vulcanized O-Rings‘).

Vulcanized O-Rings

Vulcanized O-Rings Description:

Vulcanized O-rings are made from extruded cord stock that has been cut and bonded together, as opposed to molded o-rings that are compression or injection molded as one piece. Vulcanized O-rings are the perfect choice for static sealing applications when molded o-rings cannot be used due to large or non-standard dimensions, or when you need only a few pieces, or when you need an O-ring immediately and cannot wait the standard time needed for molded production.  It can be made from a range of elastomers and in any size you need. These O-rings are a good choice for all the static sealing applications or ones where the O-ring does not come in contact with moving parts. They are not recommended to be used in dynamic applications.

The most important factors affecting the quality of this product are the mechanical characteristics and dimensional accuracy of the extruded cord stock. Over recent years Eriks has formulated special compounds which give very low compression set figures which are critical for high quality vulcanising.


Excellent heat resistance with continuous service temperature capability of 446°F, chemical resistance including resistance to strong acids and bases, high electrical resistivity, excellent oil resistance.
