Description
Choosing the right custom hermetic seals
We have designed thousands of custom seals for customers in a broad range of industries. Our engineering team take the time to understand your custom requirements and our speciality is then finding a standard hermetic seal or designing a custom hermetic seal specifically for your application.
Whether you have a cable or wire feedthrough, flex circuit, thermocouple including coax, fiber optic, computer equipment connectors, military connectors or nearly any connector, we can build custom seals for them all. We also have large flanges and portplates with multiple hermetic feedthroughs mounted onto the plate, which are tested and ready for installation. The large conflat flanges often have tens to hundreds of connectors and wires sealed into them.
Custom epoxy seals
Epoxy custom seals have outgassing and leak rates as low as ceramic seals but with even better flexibility in low and high volume needs. The expoxy seals can effectively seal gases and fluids, including helium gas, with very low helium gas rates. Epoxy seals are the best choice for custom shapes and designs.


If you have an existing connector, wire or cable in your system that you require sealed or you need a prototype or assistance designing a custom seal for your application, please e-mail us: [email protected].
When you e-mail us your custom seal enquiry, please provide as many relevant details as possible, such as:
- Connector Type
- Pressure or Vacuum level
- Gases or liquids that will be in contact with the system
- Temperature range
- Electrical requirements
- Frequency of the system
- Wire or cable length and gauge
- Number of conductors
If you can give us as much information as possible with regards to the above bullet points, this will help us to ascertain whether we have an off-the shelf option for you or if you would require a custom seal. An idea of quantity and lead time required would also be very useful.
