Custom manufacturing of U & E shaped silicone gaskets – Precise & reliable sealing

Custom U-Shaped and E-Shaped Silicone Seals are professional sealing solutions widely used in applications that require high sealing efficiency, excellent elasticity, and precise dimensions. Manufactured from high-quality silicone rubber, these seals are designed to perform reliably in demanding environments such as cold storage systems, industrial machinery, technical cabinets, and door sealing applications.

With U-shaped and E-shaped cross-section designs, silicone seals can fit tightly into gaps, grooves, or along door edges, helping to prevent air, water, dust, and cold leakage. This makes them an ideal choice for customers looking for durable, long-lasting sealing products that can be customized to specific requirements.

Key features of U-shaped and E-shaped silicone seals

U-shaped silicone seals are designed for simple installation and edge protection. They are commonly used to cover metal or plastic edges and to seal straight gaps. Thanks to their flexible structure, U-shaped seals are easy to press into place and provide stable sealing performance.

E-shaped silicone seals feature multiple sealing lips, which significantly improve sealing efficiency. This profile is especially suitable for cold room doors, cold storage systems, and refrigeration equipment, where tight sealing is essential to reduce energy loss and maintain stable temperatures.

Both profiles are made from silicone rubber, offering excellent elasticity and resilience. Even after long periods of compression, the seals can return to their original shape without cracking or hardening, ensuring a long service life.

Temperature resistance and durability

One of the biggest advantages of silicone seals is their wide operating temperature range, typically from -60°C to +200°C. This allows U-shaped and E-shaped silicone seals to perform well in both low-temperature environments such as freezers and high-temperature industrial settings.

In addition, silicone rubber provides strong resistance to UV radiation, ozone, moisture, and aging, making these seals suitable for both indoor and outdoor applications. They do not easily deteriorate over time, even under harsh working conditions.

Easy installation and maintenance

U-shaped and E-shaped silicone seals are designed for quick and convenient installation. In most cases, they can be installed by simply pressing them into grooves or onto edges without the need for adhesives or complex tools. This helps save installation time and labor costs.

When maintenance or replacement is required, the seals can be easily removed and replaced without damaging surrounding components, making them a practical choice for long-term use.

Wide range of applications

Custom U-shaped and E-shaped silicone seals are commonly used in:

• Cold storage doors, cold rooms, and refrigeration systems

• Aluminum, steel, and glass doors

• Electrical cabinets and control panels

• Industrial machinery and production lines

• Equipment requiring dustproof, waterproof, or thermal sealing

Their versatility makes them suitable for factories, workshops, warehouses, and commercial facilities.

Custom manufacturing to your requirements

These silicone seals can be custom-manufactured according to customer drawings or physical samples. Dimensions, hardness (Shore A), color, and length can all be adjusted to match specific applications. The production process supports small batch orders as well as large-volume manufacturing, ensuring flexibility for different customer needs.

Conclusion

With excellent sealing performance, high elasticity, wide temperature resistance, and precise custom manufacturing, U-shaped and E-shaped silicone seals are reliable solutions for a wide range of sealing applications. They help improve system efficiency, reduce energy loss, and lower maintenance costs over time.
