SealsHub supplies 20 x 30 mm solid D shape silicone sponge seal strip designed for applications requiring a high-profile sealing section with increased compression travel and deeper gap compensation capability. The taller D-shaped structure provides an enlarged rounded sealing surface while maintaining a stable mounting base, helping deliver consistent contact and flexible sealing performance.
This silicone sponge profile is suitable for larger equipment interfaces, protective enclosures and custom sealing systems where additional cushioning, impact absorption and reliable compression recovery are required. The increased height makes it suitable for applications with deeper sealing gaps while maintaining a compact installation width.
