Custom Seals and 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.
As it stands, there has never been a connector that our team have been unable to seal, so whatever your connector, please contact our team today for your custom hermetic seals.
Choosing the right Custom Hermetic Seals
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.
We can design and produce custom seals for every industry from medical facilities and labs to airport equipment. Every custom hermetic seal we manufacture goes through a rigorous test process, including pressure leak tests, helium testing, high voltage testing, and/or continuity testing. This ensures every seal we ship is robust.
We seal all types of cables, including coaxial, twisted pair, multiconductor, fiber optic, shielded cables, and even multiple shields like HDMI and triax cables. If you need a custom vacuum cable seal, we offer flexible, cost-effective designs manufactured to the exact specifications of your project. Please refer to Custom Cable Seals for further information.
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.
With excellent resistance to oils and gasoline, epoxy seals are also the ideal choice for energy, aerospace, and automotive industries with the ability to withstand high pressure and temperatures ranging from -100C to 250C.
Epoxy hermetic seals even come with the design flexibility to seal copper alloy pins or wires rather than using the far less electrically conductive nickel-iron pins used in glass hermetic seals. Epoxy seals can be routed through tight spaces and angles, tightly seal any feedthrough shape, and handle any type of cable or wire. They are frequently used to solve design challenges that can’t be addressed easily with glass or ceramic seals.
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.
