Overmoulded Connectors

Overmoulded Connectors for The Military

The Military is, without much argument, one of the most important industries for each country in the world.  The technology that is used needs to be working at its best, always.  It is without exaggeration that the importance of all the technology and vehicles used by the military could have life or death consequences.

The environments that these machines and vehicles have to operate in can be hostile and unpredictable.  Whether it’s a drone flight through sand storms in The Middle East, a fighter jet in turbulence, or a naval vessel navigating the choppy waters of the ocean, the technology needs to be protected.  And it isn’t solely about water ingress.  If dust or chemicals get inside the technology, people could be at risk.  That’s why Military Vehicles need to be durable and prevent dust and liquid ingress.

GK Services stock a variety of military grade connectors such as Souriau that are perfect for military applications.  These integral components are designed to make sure the life saving equipment stays on top of its game.

Why Overmoulded Connectors Are Ideal for Military Tech and Vehicles

Overmoulded connectors are becoming increasingly popular in high speed and dangerous sectors. Their performance benefits over traditional connector systems make them particularly suitable for the fast-paced, high-demand settings of modern manufacturing.

Superior Durability
The overmoulded housing forms a robust, sealed barrier. This protects internal connections from moisture, dust, vibration and mechanical stress. The durability covers all common hazards found on in various harsh environments across the globe.

Customised Integration
Overmoulding allows for tailored shapes, cable orientations and strain relief features. This means connectors can fit neatly into tight spaces or complex machinery layouts without losing performance.  They can be easily installed at times of severe duress.

Streamlined Installation
By moulding the housing directly around the connector and cable, overmoulded solutions reduce the number of separate parts needed. This simplifies installation, reduces the time it takes to assemble and enhances overall efficiency.

In military environments, where downtime is fleeting and conditions can be tough, overmoulded connectors provide a robust, timely and future-proof solution to ensure connectivity at all times.

Sealed for Performance: Souriau's Military Grade Connectors

Trim Trio Range – All Souriau connectors in this family share common contact styles and sizes, making them fully interchangeable across the range. This ensures flexibility in design and simplifies logistics for military and defence projects.

UTS – A high-performance plastic connector based on the Military 26482 standard. Specifically developed for use in hostile environments where metals may corrode or tarnish. Rugged, lightweight, and cost-effective, the UTS is widely used in ground support and field-deployed systems.

  • 250 mating cycles

  • Operating temperature: -40°C to +105°C

  • Vibration resistance from 10 to 2000 Hz

  • IP-rated sealing options, even when unmated

UTO – A robust metal-bodied version with plastic inserts, otherwise identical to the UTS. The metal shell provides superior EMI shielding, while the metal coupling ring increases durability to 500 mating cycles. Ideal for applications where electromagnetic resilience and extended service life are critical.

851 – The full-metal, military-grade connector within the range. Designed to meet stringent defence standards, it withstands 500 hours of salt spray testing, ensuring reliability in naval, aerospace, and battlefield conditions.

GK Services – We have tooling in place for straight and right-angle moulds in shell sizes 8, 10, 12 and 14. All designs have been tested and approved to IPX6, IPX7 and IPX8, making them fully suitable for demanding military environments where water ingress protection is essential.

Important Features for the Military

Overmoulded connectors offer more than just a solution for water ingress. They provide several benefits that make them invaluable in a range of industries:

Military Battleship
  • Waterproof Protection
    Overmoulded connectors deliver a watertight, IP-rated seal that protects critical connections from rain, washdowns, condensation, and immersion. In military environments — whether naval, aerospace, or field operations — this level of protection ensures uninterrupted performance even in the harshest and most unpredictable conditions.

    Exceptional Durability
    Built for mission-critical use, overmoulded connectors withstand mechanical stress, vibration, and extreme thermal cycling often encountered in armoured vehicles, aircraft, and field-deployed equipment. This ruggedness reduces the risk of downtime caused by wear, loosening, or fatigue in combat or training scenarios.

    Consistent Electrical Performance
    By excluding moisture, dust, and debris, overmoulded connectors maintain stable and reliable electrical performance under battlefield conditions. This consistency minimises unexpected faults and extends the service life of critical defence systems.

    Versatile Integration
    Overmoulding supports a wide variety of connector types, from soldier-worn electronics and sensor packages to vehicle harnesses and aerospace systems. This flexibility allows for custom solutions tailored to exact military specifications, ensuring compatibility across diverse platforms.

    Tamper-Resistant Security
    The sealed, encapsulated design of overmoulded connectors prevents accidental disconnection or unauthorised interference. This added resilience is essential for safety-critical military applications, where operational integrity must be guaranteed under pressure.

Overmoulded Connectors Are Essential

In defence operations, critical equipment and control systems are constantly exposed to extreme conditions including moisture, dust, vibration, and heavy mechanical stress. Water ingress is a common cause of failure, leading to corrosion, electrical faults, and in worst cases, complete system shutdowns. Such issues can compromise mission readiness, disrupt field operations, and create significant safety risks.

Overmoulded connectors provide a rugged and dependable solution. By creating a fully sealed, tamper-resistant barrier around the connector and cable junction, the overmoulding process delivers long-term protection across the full service life of military vehicles, aerospace systems, and field-deployed equipment.

In mission-critical environments where reliability and continuous operation are non-negotiable, and where systems must endure the harshest conditions, overmoulded connectors ensure consistent performance. They protect system integrity, reduce maintenance demands, and help keep operations running safely and effectively in the most challenging theatres.

Aesthetics and Functionality Combined

While the practical benefits of overmoulded connectors are well recognised, their design and presentation also carry value, particularly in defence applications where equipment must meet both operational standards and strict military specifications.

Overmoulded connectors deliver not only strong environmental protection but also a uniform, professional finish that enhances the appearance of control panels, vehicle interiors, and field-deployed systems. In military settings where equipment is subject to inspection, integration with allied forces, or high-profile deployments, these connectors help present a disciplined and consistent standard.

The overmoulding process can be tailored with colour-coded housings, textured finishes or reinforced designs to meet both functional requirements and theatre-specific demands, such as camouflage integration or rapid identification in the field. This ensures connectors perform reliably while aligning with broader operational and logistical needs.

By combining battlefield durability with precise design, overmoulded connectors are a smart choice for modern defence systems where mission reliability and professional presentation are equally critical.
