Vulcanised O Rings

Rubber O Rings

Nufox are a high quality extruded and hot vulcanised O rings manufacturer

(joined o-rings) with high tolerances on dimensional accuracy and material consistency. Such products are used in a wide variety of different OEM applications where the cost of a moulded seal (especially tooling) is prohibitive.

These custom made parts are manufactured using Nufox’s in-house extrusion facilities; the compounds used achieve market leading levels of ‘compression set’. The highly developed hot vulcanisation process developed by Nufox, gives custom extruded products very high joint strength. Typically, our joint strength is 80-90% of a fully moulded product, yet gives shape, profile, flexibility and speed of turn-round!

Frequently Asked Questions

How does the process work?

We can take your concept through design, sampling, to finished product in-house, with complete control throughout. We have a number of processing options, and our total in-house control of design, manufacturing and tooling ensures that we can maintain timelines and achieve your delivery expectations.

Are your products bespoke?

Yes, at Nufox we provide you with a product that is totally compatible to your design and functional requirements.

Are there minimum order quantities?

No, but many of our products require tooling development, processing machine set up and compound selection. So the costs involved in this process have to be allocated to the project. But if a small quantity is required for fit and function, this can be accommodated.

What are the lead times for a product?

If the product is a new development requiring tooling, this can often be less than four weeks. However if the project is complex and requires a specially formulated compound, this can be longer. Once we have your enquiry, we are able to give you an indicative production time.
