4 Reasons to Choose Custom Rubber Seals and Gaskets

Seals and gaskets are used in a wide range of industries to provide a strong watertight and airtight fit between either stationary or moving parts. Custom options are often required for more specialized purposes, and the material you choose is going to make a significant impact on how those products perform.

While all seal and gasket materials have their own pros and cons, custom rubber is often the best choice. Here are just four reasons why.

1. Resistance to Extreme Temperatures

Seals and gaskets are often subjected to extreme temperatures. While some materials cope well enough with extreme heat and others with extreme cold, rubber is capable is withstanding temperatures at both extremes, with silicone rubber being particularly impressive in this regard. As such, rubber seals and gaskets are often the ideal choice in environments that are frequently subjected to swings in temperature. They'll maintain a strong seal, and they won't degrade under such conditions.

2. Highly Versatile

Rubber's high malleability means that custom shapes and sizes are relatively easy to produce, so you can opt for anything from standard O-rings to more bespoke options and trust that rubber's versatility will satisfy your needs. Additionally, the manufacturing flexibility of rubber allows different materials to be added in order to create a wide variety of rubber seal and gasket types that are ideal for a wide range of uses. You can choose between soft rubbers and hard rubbers, and it's also possible to create rubber seals and gaskets in different colours. While this may be done simply for aesthetic purposes, it can also help improve safety.

3. Long-Term Durability

The unique microstructure of rubber compounds allow them to be stretched and compressed without being rapidly degraded. Though no seal or gasket will last forever when subjected to regular pressure, the rubber will last longer than other options, including FEP (fluorinated ethylene propylene), polyurethane and polyacrylate. Since it can stretch and compress so effectively, you can count on rubber maintaining an airtight and watertight seal long after those other materials have failed.

4. Impressive Compatibility

The vast majority of rubber seals and gaskets are completely non-toxic. As such, it won't compromise the grooves or any other parts of the objects it is meant to protect. Just as importantly, rubber seals and gaskets are compatible with compounds that can damage other materials. This is why they are often used in chemical facilities, where they may encounter various acids and alkalis. They can also be used in drainage pipes for various liquids without worrying about degradation.
