Hot Vulcanised O-Rings – The Ultimate Choice for Diverse Applications

NES is a market leader in the manufacture of hot vulcanised O-rings, offering outstanding tolerances and a joint strength of 90% of a fully moulded product.  Our high-quality materials, such as those provided by Chemours™, ensure a low compression set for top-quality VulcOrings. 

VulcOrings, or cord rings, are versatile sealing solutions used across diverse applications and markets due to their profile and material options, offering a cost-effective and quick alternative to moulded seals.
