Electrical Connector Sealing Solutions Built for Reliable Environmental Protection
Forest City Technologies manufactures molded seals, die-cut foam gaskets, and potted components that help protect electrical connector systems from moisture, dust, fluids, vibration, temperature exposure, and other demanding operating conditions.
Electrical connectors often operate at the point where power or signals must pass through a housing while the assembly remains protected from the surrounding environment. If the seal is not correctly matched to the connector design, material interface, compression requirement, and service conditions, moisture, dust, automotive fluids, vibration, and thermal cycling can contribute to corrosion, electrical instability, premature component failure, and warranty risk.
Forest City Technologies helps customers integrate sealing into the connector assembly through custom molded seals, precision die-cut foam gaskets, and controlled potting processes. Our team reviews the part geometry, substrate, sealing path, compression needs, temperature and fluid exposure, production volume, and assembly method to help develop a repeatable solution that is practical to manufacture and reliable in use.
Electrical Connector Sealing Capabilities
Molded Seals
Custom molded seals provide reliable environmental protection for electrical connectors by sealing around complex geometries, wire interfaces, and mating surfaces. Forest City Technologies designs and manufactures molded sealing solutions that help protect against moisture, contaminants, fluids, and harsh operating conditions while supporting long-term performance in demanding applications.
Die-Cut Foam Gaskets
Custom die-cut foam gaskets provide sealing, cushioning, insulation, and vibration control for electrical connectors and electronic assemblies. Using a wide range of foam materials and precision converting processes, Forest City Technologies creates gasket solutions that improve assembly, fill gaps, and help protect components from dust, air, moisture, and mechanical stress.
Potting
Potting enhances the durability and reliability of electrical connectors by encapsulating sensitive components with specialized sealing materials. Forest City Technologies provides precision dispensing and potting solutions that help protect against moisture, chemicals, vibration, and thermal cycling while improving strain relief and long-term connector performance.
Key Benefits
- Integrated environmental protection: Build sealing performance into the connector, housing, gasket, or potted cavity.
- Application-specific material options: Align material behavior with temperature, fluid, compression, flexibility, and electrical requirements.
- Reduced assembly complexity: Replace loose or manually applied sealing steps with production-ready components where appropriate.
- Repeatable geometry and placement: Support consistent molded features, converted gaskets, and dispensed fill levels.
- Design flexibility: Address complex connector shapes and combine molding, converting, dispensing, and value-added assembly as needed.
- Production scalability: Move from application review and tooling considerations toward controlled repeat manufacturing.

What types of electrical connector seals does FCT manufacture?
FCT supports custom molded perimeter seals, grommets, O-rings, interfacial seals, face seals, die-cut foam gaskets, and potted connector or electronic assemblies.
How do I choose between a molded seal, foam gasket, and potting?
The best approach depends on the connector geometry, whether the joint must be opened or serviced, compression and movement, environmental exposure, material compatibility, assembly sequence, and production volume. Some applications use more than one sealing method.
Can FCT support harsh automotive and industrial environments?
FCT works with material and process options intended for demanding conditions involving moisture, dust, vibration, thermal cycling, and exposure to automotive or industrial fluids. Final material selection and validation should be based on the customer’s specific requirements.
Can FCT help with material and design decisions?
Yes. FCT can review part geometry, substrate, sealing path, temperature and fluid exposure, compression, dispensing, tooling, and assembly considerations to help define a manufacturable solution.
Can FCT support production-scale connector sealing programs?
FCT supports repeat manufacturing programs across molding, converting, dispensing, and value-added assembly. Production requirements, validation expectations, and capacity should be reviewed for each program.
