Hermetically Sealed Adapters
SRFS Teleinfra offers hermetically sealed adapters for RF and microwave interconnection applications that require reliable electrical connectivity and protection against environmental ingress. Designed for demanding operating conditions, these adapters can provide a sealed interface between connected components while maintaining the required RF signal path.
Hermetically sealed adapters are used in applications where moisture, gas leakage, pressure differences, or contamination must be controlled. Depending on the design, connector interface, sealing technology, and specified test requirements, they can support equipment used in aerospace, defense, industrial electronics, instrumentation, and communication systems.
As an RF components supplier, SRFS Teleinfra supports customers seeking dependable adapter solutions for specialized RF and microwave assemblies. Connector types, mounting arrangements, operating frequency, materials, and sealing requirements should be confirmed according to the intended application.
What Are Hermetically Sealed Adapters?
Hermetically sealed adapters are interconnection components designed to provide an electrical connection while maintaining a gas-tight or otherwise specified environmental seal. Unlike conventional adapters, which primarily connect two different or matching connector interfaces, hermetically sealed designs incorporate sealing features intended to prevent unwanted passage of gases or fluids through the specified sealing boundary.
These adapters may use glass-to-metal seals, ceramic feedthroughs, brazed joints, specialized insulating materials, or other engineered sealing methods, depending on the construction. The exact sealing method and leak-rate performance vary by product design.
They can be used to connect RF transmission paths across equipment housings, sealed enclosures, instrument panels, and other assemblies where maintaining enclosure integrity is important.

Types of Hermetically Sealed Adapters
RF Hermetically Sealed Adapters
These adapters are designed for radio-frequency signal paths and may be available in different connector interfaces. Their electrical performance depends on connector geometry, impedance, frequency range, and the quality of the RF transition.
Microwave Hermetically Sealed Adapters
Microwave versions are intended for higher-frequency applications where impedance matching, insertion loss, return loss, and mechanical precision are important. The supported frequency range must be verified for the selected model.
Bulkhead Hermetically Sealed Adapters
Bulkhead designs allow an electrical connection to pass through a panel or enclosure while maintaining the specified seal at the mounting interface. Mounting dimensions and sealing arrangements depend on the product design.
Flange-Mounted Hermetically Sealed Adapters
Flange-mounted versions are used where a bolted or flange-based mounting arrangement is required. Flange dimensions, hole patterns, gasket interfaces, and mounting torque should be checked against the applicable drawing.
Custom Hermetic RF Adapters
Custom configurations may be considered for projects with specific connector combinations, panel dimensions, environmental requirements, or electrical performance targets. Availability depends on design and manufacturing capabilities.

Frequently Asked Questions
A hermetically sealed adapter is an electrical interconnection component designed to maintain a specified gas-tight seal while providing an electrical connection across an interface.
A standard RF adapter primarily connects compatible connector interfaces. A hermetically sealed adapter incorporates additional sealing features intended to control leakage across a defined boundary.
Possible configurations include SMA, N-Type, TNC, and other RF interfaces. Actual availability depends on the manufacturer’s product range and application requirements.
Yes, provided the selected model is rated for the required frequency range and meets the application’s insertion loss, return loss, and other RF performance requirements.
Hermetic sealing means maintaining a specified barrier against gas or fluid passage. The acceptable leak rate and verification method must be defined for the application.
A helium leak test uses helium as a tracer gas to detect leakage through a sealed component or assembly. The required acceptance limit depends on the relevant product specification or qualification standard.
Yes. Depending on the design, they may be available in bulkhead or flange-mounted configurations. The mounting dimensions and sealing interface should be verified before installation.
There is no single frequency range for all hermetically sealed adapters. Performance depends on the connector design, internal geometry, materials, and specific model.
