Common Pitfalls When Sourcing Hermetically Sealed Connectors (Quality, IP)

Sourcing hermetically sealed connectors requires careful attention to detail, as these components are often critical for reliability in harsh environments such as aerospace, defense, medical, and industrial applications. Overlooking key aspects can lead to performance failures, safety risks, and costly field repairs. Below are common pitfalls related to quality and Ingress Protection (IP) ratings.

Inadequate Verification of True Hermeticity

One of the most critical mistakes is assuming that a connector labeled “hermetically sealed” meets the required leak-tight standards. True hermeticity means the connector prevents the passage of gases and liquids at a molecular level, typically measured via helium leak testing (e.g., per MIL-STD-883 Method 1014). Without verified test data or certification, suppliers may offer merely “environmentally sealed” connectors, which do not provide the same level of protection.

Overreliance on IP Ratings Alone

While IP (Ingress Protection) ratings indicate resistance to dust and water (e.g., IP67, IP68), they do not guarantee hermetic sealing. IP tests are conducted under specific conditions—often with water immersion or spraying—but do not assess long-term gas permeability or performance under vacuum or extreme pressure. Relying solely on IP ratings may result in selecting connectors that fail in high-altitude or vacuum applications.

Poor Material and Construction Quality

Low-quality materials—such as inferior glass-to-metal seals, substandard epoxy seals, or poorly plated contacts—can compromise sealing integrity. For example, epoxy-sealed connectors may degrade over time due to thermal cycling or exposure to chemicals, leading to microcracks and leaks. Always verify the sealing method (e.g., glass, ceramic, or metal weld) and ensure materials are suitable for the operating environment.

Lack of Traceability and Certification

Hermetic connectors used in critical applications require full traceability and compliance with industry standards (e.g., MIL-DTL-38999, MIL-DTL-26482, or ASTM E493). Sourcing from unauthorized or uncertified distributors increases the risk of counterfeit parts. Ensure suppliers provide full documentation, including lot numbers, test reports, and compliance certificates.

Incompatibility with Environmental Stresses

Even high-quality hermetic connectors can fail if not selected for the specific environmental conditions. Factors such as extreme temperature cycling, vibration, shock, and exposure to corrosive chemicals must be considered. Using a connector rated for IP68 in a high-vibration aerospace system without verifying mechanical durability can lead to premature failure.

Incorrect Installation or Mating Procedures

Hermetic performance depends on proper installation. Over-torquing or under-torquing threaded couplings, using incorrect tools, or damaging seals during assembly can break the hermetic seal. Always follow the manufacturer’s recommended installation procedures and use calibrated tools.

Failure to Conduct In-House Testing or Validation

Assuming supplier claims without in-house validation is risky. Implement incoming inspection protocols such as helium leak testing, visual inspection under microscopy, and electrical continuity checks. This helps catch defects early and ensures compliance with internal quality standards.

Choosing Based on Price Over Performance

Opting for the lowest-cost option often leads to compromised reliability. Hermetic connectors involve precision manufacturing and rigorous testing—corner-cutting to reduce cost typically results in lower quality. Invest in connectors from reputable manufacturers with a proven track record in mission-critical applications.

By avoiding these common pitfalls, engineers and procurement teams can ensure they source hermetically sealed connectors that deliver long-term reliability and meet the stringent demands of high-performance applications.
