3 Factors to Consider When Choosing a Plastic Cable Seal

Plastic security cable seals are used in a wide range of applications. With a comprehensive collection of sizes and designs, it can be a challenge for engineers and purchase managers to choose the right one for their needs. Here are three factors to consider when choosing a plastic cable seal.

Quality Material

When considering cable connectors seals, it’s important to consider the quality of the material. The plastic should have a high pull strength to secure against potential attacks while being flexible for easy locking. Nylon and polypropylene plastic hermetic terminal seals can provide this protection, especially with smaller components that can easily dislodge. A high quality plastic seal can be beneficial over aluminum seals in environments where water can cause corrosion or friction.


Overmolding provides greater reliability and a longer lifespan by injecting a layer of material over the plastic component. This can help provide insulation against shock from sparks of electricity measuring up to 3,000 volts. A high-pressure hermetic seal with overmolding can survive the most rugged environments by ensuring subsea connectors are tamper proof and water resistant. The overmolding can be customized with any type of imprint such as logos and codes for special applications.

Design considerations must be carefully made prior to any overmolding project. Any error can affect production time and cost. Testing before production is crucial to avoid any errors. If overmolding is done right, it can significantly enhance the feel, appearance and quality of the seals.


When choosing a plastic cable seal, consider how many applications it can be used for. Diversification allows you to be able to save time and money when developing several projects. Seals can’t typically be reused and there are strict regulations with disposal. You can avoid the hassles with these issues by selecting a hermetic connector useful across a broad range of industries.

Choosing the right cable seal can take time and effort to ensure the highest quality. It’s important to do your due diligence and seek out expert help and advice. By choosing the best cable seals, you can control costs and keep customers satisfied.
