Custom hermetic seals designed and manufactured to meet your needs

RHSeals creates custom hermetic seal designs for a broad range of industries. This includes seals for nearly any connector, cable or wire, flex circuit, and thermocouple, including coax, fiber optic, computer equipment connectors, and military connectors. We also make large flanges and portplates with multiple hermetic feedthroughs mounted to the plate, tested and ready for installation.

Our Process

Our experienced engineering team oversees every made-to-order hermetic seal project from the early design stages through the manufacturing process. Most of our custom pressure feedthrough and vacuum feedthrough seals begin with an email from a customer with a specific fiber optic, cable, wire, or connector that is already in their system, but needs to be sealed. If you have a connector or wire you want to supply, it can be used to create your custom Reliable Hermetic Seal.

From the design stage through the life of your product, every seal and feedthrough we manufacture receives a rigorous electrical test, leak test, visual inspection, and comes backed by a limited lifetime warranty.

Achieve greater flexibility in your projects with cost-effective custom solutions and short lead time. Whether you need a prototype, need to seal an existing wire or cable in your system, or need assistance designing a hermetic seal for your application, contact us for help.
