What is special about hermetic seals? A hermetic seal allows current or signal to transfer between two separate environments. The transfers are made without interruption from moisture, gases, or particles leaking. This leads to a wide variety of applications in many industries where the highest of standards are required. Aerospace, Military, Medical, Ground Transportation, Oil and Fuel, to name a few, all have precise requirements that ensure safety from moisture, temperature, and even explosion proof standards. Hermetic seals are special due to the combination of engineering and materials involved. RHSeals offers a wide range of products including custom hermetic seals. Due to the requirements of the product, testing is a key component in the making of a reliable hermetic seal. 100% of our products are tested and certified to meet the requirements on each drawing. Our products are reliable and affordable and come with [...]

Industry Series: Medical The medical industry has diverse hermetic seal needs, and hermeticity has greatly evolved over time to meet different sterilization and functionality requirements. Hermetic seal use in the medical field begins with Research & Development, and continues in implantable devices and medical equipment. While a hermetic seal may not be required in every situation, when hermeticity is a requirement, quality is a necessity. X-Ray machines, CT machines, laboratory equipment, computers, glove boxes, sterilization equipment, etc. need to perform invariably. These devices require that power and signals can pass through properly, despite coming in contact with different environments. Dust and moisture cannot pervade any seals; this could affect readings, accuracy, and the operations of the equipment systems. Equipment that is used daily at hospitals or medical centers needs to meet the highest standards. When lives are on the line, reliability cannot be compromised. There are important considerations when choosing [...]

What is Bubble Testing? It is a simple, widely used qualitative method for proof testing and for finding defects or gross leaks in many different components. Two common forms of bubble testing are the direct-pressure method and the vacuum-box technique: The pressurized method (the most common bubble testing method) is conducted by pressurizing a component with a gas and then either submerging it in a solution or applying a solution to the outside of the component. If a leak is present, bubbles will form on the surface because of the leak passing through the solution. The vacuum-box method is conducted on parts that cannot be directly pressurized or where access is not available to both sides of a component. The test is conducted by applying a solution to an area of a pressure-boundary surface and creating a different pressure across the area, causing the formation of bubbles as leakage gas, [...]

Custom hermetic seals designed and manufactured to meet your needsRHSeals 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 ProcessOur 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 [...]

Do you know the operating temperature required? Often hermetic feedthrough operating environment requirements are pulled from design specifications for the system it’s going into. Sometimes this is acceptable but often it will add unnecessary costs and delays to the project. When specifying operating requirements it is important to determine the environment for the location of the hermetic seal within the system. The three most critical operating environment questions we want to know when designing a custom hermetic feedthrough are: The pressure or vacuum level on each side of the feedthrough. Any gasses or liquids that can contact the hermetic seal assembly. What is the temperature range the feedthrough will experience. Most customers have a good understanding of the first two questions. The most common error we see is with temperature at the feedthrough. For example, a customer was running a high temperature experiment inside a glovebox and needed a thermocouple [...]

Mark Nuttbrock, President Reliable Hermetic Seals, LLC Part Buyers Authority, Fall 2019 Reprinted with permission from Part Buyers Authority  www.partbuyersauthority.com Hermetic seals have been around for centuries, and they continue to evolve with technology and innovation. Hermetic seals used in manufacturing can be applied to many different industries; in fact, you probably come across hermetic seals in your day-to-day life. These seals allow currents or signals to be transferred between two separate environments. The transfers are made without interruptions from moisture, gases, or other particles leaking. If any leakage occurs, they can wreak havoc on one or both environments. And, in some cases, any dust or other small particles passing through can cause explosions. By using hermetic seals, the risk for damages is minimized; hence, the need for a reliable hermetic seal. So, what exactly do hermetic seals actually do? Hermetic seals: Provide a passage of currents or signals [...]
