Solid Arch Silicone Seal Strip
Product Overview
Solid Arch Silicone Seal Strip is a high-performance extruded silicone rubber gasket and sealing profile designed for industrial sealing applications requiring excellent compression recovery, temperature resistance and long-term durability.
The solid arch profile provides a reliable sealing solution for blind valves, centrifuge covers, kneader machines and other industrial equipment. Its strong elastic structure helps maintain sealing performance under repeated compression, vibration and high-temperature working conditions.
Manufactured from premium silicone rubber, these sealing profiles are suitable for demanding environments including chemical processing, food machinery, drying equipment and industrial production systems.
Key Features
- High Temperature Resistance
Silicone rubber maintains stable sealing performance under extreme temperature conditions, making it suitable for steam equipment, dryers, ovens and industrial machinery.
- Excellent Compression Recovery
The solid arch design provides strong resilience after repeated compression, helping prevent leakage and improve service life.
- Weather & Aging Resistant
Silicone material offers excellent resistance to:
- UV exposure
- Ozone
- Moisture
- Environmental aging
Suitable for many industrial environments requiring stable sealing performance.
- Custom Extruded Profiles Available
Different sizes, hardness, colors and lengths can be customized according to drawings or samples.

Length Selection Guide
Silicone seal strips are available in different lengths depending on profile size, application requirements, shipping method, and order quantity.
• Standard lengths: Most specifications are available in common lengths such as 1 m, 3 m, and 10 m, suitable for sample testing, replacement parts, and regular applications.
• Large profiles: Due to their larger dimensions and shipping requirements, some long-length options may be limited by standard transportation methods. These profiles can be shipped by express, air freight, or sea freight according to customer requirements.
• Bulk orders: For wholesale orders and engineering projects, we offer longer rolls, custom lengths, and production quantities based on project requirements.
• Custom production: If a requested size or length is not currently listed, we can manufacture it using our existing extrusion tooling. Additional tooling charges may not apply when suitable existing tooling is available.
Please select the available length option for each specification. For special lengths, bulk orders, or customized requirements, please contact us for a suitable solution.
