*Automatic Visual Inspection

Inspecting finished components is a crucial part of any production process, guaranteeing the required quality level in each element. Each manufactured batch is 100% inspected. The automated selection department with various machines for visual inspection are able to inspect the (surface) quality and dimensions of O-rings and drawn parts.

**Polymer Laboratory

NewDealSeals researches, develops and formulates new elastomers in the polymer laboratory. We work closely with the most important polymer producers, suppliers of mixtures and certifying institutes. For instance, we have developed peroxide-cured fluoroelastomers for steam applications, our own FFKM range Fluorezi® and special petrol-resistant elastomers.



Environments involving high pressure, high temperature or minimum idle time demand a perfect sealing solution. With customers such as Shell, we continuously work on new sealing solutions. NewDealSeals offers numerous options for sealing products for chemical installations. Our range includes among other things O-rings in FKM (Viton®), FFKM (Fluorezi®, Kalrez®, Isolast®, Ultra®, Simriz®), drawn parts (moulding) and PTFE (Teflon®) seals.

Building & Construction

NewDealSeals is actively involved in the building and construction machinery industry. With customers such as CATERPILLAR & HITACHI, we also continuously work on new sealing solutions.

Our range includes standard O-rings in all imaginable materials, custom moulded parts, rotary shaft seals, V-rings and completely packaged sets with spare parts. NewDealSeals understands the importance of (spare) parts for your business. Therefore, we also offer customised packaging solutions.


Did you know that worldwide, more than 60% of all engines in cargo vessels are fitted with NewDealSeals seals? Our range of O-rings, D-rings, V-rings, gaskets, PTFE (Teflon®) parts and sealing sets for industrial 2 and 4 stroke engines is globally unique. With customers such as CATERPILLAR, Doosan, HITACHI, Hyundai, Kawasaki, MAN Diesel & Turbo, MITSUI, STX and Wärtsilä we continuously work on new sealing solutions.

Such solutions have for instance lead to the successful introduction of steam-resistant peroxide-cured Viton® for cylinder linings, but also material tracers in our O-rings and permanent markings on O-rings.

Foodstuffs & Dairy Products

NewDealSeals also develops and supplies sealing products that comply with the FDA hygiene standards. Our range includes O-rings in FDA approved materials, FKM (Viton®), FFKM (Fluorezi®, Kalrez®, Isolast®, Ultra®, Simriz®), drawn parts (moulding) and PTFE (Teflon®) seals.

Health Care

NewDealSeals is actively involved in the development of sealing products for medical components. With customers such as Belimed and Philips, we continuously work on new sealing solutions. Our range includes O-rings in FDA approved materials, FKM (Viton®), FFKM (Fluorezi®, Kalrez®, Isolast®, Ultra®, Simriz®), custom moulded parts and PTFE (Teflon®) seals.


Semiconductor production is a particularly aggressive process. Here, seals are often exposed to extreme conditions, such as strongly corrosive liquids, gases and plasmas at high temperatures or in a vacuum. In this sector, NewDealSeals develops sealing solutions that match your specific requirements.

What can NewDealSeals produce for you? Our range includes among other things high purity O-rings, FKM GF (Viton®), FFKM (Fluorezi®, Kalrez®, Isolast®, Ultra®, Simriz®), and PTFE (Teflon®) seals.
