SealsHub supplies 20 x 40 mm solid D shape silicone sponge seal strip designed for applications requiring an extended sealing height and substantial compression capacity. The high-profile D-shaped structure provides a deep rounded sealing surface with a stable mounting base, allowing the seal to fill larger gaps while maintaining flexible recovery performance.
This silicone sponge profile is suitable for demanding sealing applications where increased cushioning thickness, impact absorption and deep compression travel are required. The taller profile design helps accommodate uneven surfaces and larger clearances in industrial equipment, protective covers and custom sealing systems.
• High-profile D-shaped structure provides extended compression travel and deep gap filling capability
