15 x 20 mm Solid D Shape Silicone Sponge Seal Strip

Product Overview

SealsHub supplies 15 x 20 mm solid D shape silicone sponge seal strip designed for applications requiring a larger sealing profile with increased compression allowance and reliable cushioning performance. The balanced D-shaped structure combines a stable flat mounting surface with a rounded sealing face, providing consistent contact and effective gap filling during compression.

This silicone sponge profile is suitable for industrial sealing, equipment protection and custom assemblies where soft compression, vibration absorption and long-term elastic recovery are required. The larger profile design provides additional sealing contact compared with compact D-shaped sections, making it suitable for applications with wider sealing gaps.
