Types of Food and Beverage Seals
-
O-Rings
O-rings feature the ability to seal under pressure in any direction, making them an optimal choice for a wide array of applications. These seals are designed to sit between two pieces of hardware within machinery. They prevent fluid and air from entering and protect the equipment by filling the extra space between parts. At LINDE, our O-rings are available in a range of materials, allowing us to customize a solution based on your unique application.
-
Rod Wipers
Rod wipers are hydraulic seals designed to prevent contaminants or fluids from leaking into the application. These seals are typically installed as part of sealing configurations in hydraulic cylinders to prevent dirt, metallic chips, dust particles, moisture, and other contaminants from getting into the application.
-
Piston Rod Seals
These are hydraulic seals that prevent fluid from leaking in cylinders at the piston or rod gland. Leakage through the seals reduces equipment performance while potentially introducing a range of environmental issues and contaminants to products. LINDE offers a variety of seals from both single-acting and double-acting systems.
-
Custom Molded Shapes
Custom-engineered seals help ensure your equipment and systems operate exactly as you expect. This can include boots, bellows, diaphragms, grommets, and other custom shapes. If you need a custom sealing solution for your facility, the experts at LINDE Seals are here to help. Our custom sealing solutions are available in single pieces to high-volume production quantities. We also offer a variety of material options to suit different application requirements.
Application of Food and Beverage Seals
Food and beverage seals play an integral role in food packaging applications. No matter the market segment for your product, it is crucial that you find the best seals that are hygienic and durable while meeting the necessary regulatory requirements. In essence, ideal seals should prevent fluid leakage from the equipment while offering unmatched resistance to extreme temperatures, high pressures, and a range of forces within the cylinder. Some of the typical applications of food and beverage seals include:
- Optimizing production in systems equipped with proof valves
- Chemical resistance in couplings
- Pipe connections for different market segments
- Seals for beverage dispensers withstanding various temperatures

The materials used on the processing equipment should not release any chemicals and substances into foodstuff. These risks can be effectively eliminated with the right choice of sealing solution. Some of the factors to consider when choosing a sealing solution for the food and beverage industry include:
- The specific place where the seal will be used
- The fluids and foods to which the seal will be exposed
