Solid Silicone Concave Triangle Seal Strip
![]()
Product Overview
SealsHub supplies solid silicone concave triangle seal strips featuring an optimized triangular cross-section with an inward curved slope design. Compared with standard solid triangle profiles, the concave structure reduces unnecessary material volume while maintaining reliable sealing, cushioning and gap-filling performance.
The curved recessed surface provides a smoother appearance, improved space efficiency and flexible compression behavior, making the profile suitable for corner sealing, irregular gaps and applications where installation space is limited. Made from durable solid silicone rubber, this profile offers long-term flexibility, weather resistance and stable performance in demanding environments.

Application
Solid silicone concave triangle seal strips are commonly used where a triangular support profile with enhanced surface adaptation is required.
Typical applications include:
- Corner sealing for equipment housings, cabinets and enclosures
- Gap filling between panels, frames and structural components
- Cushioning pads for doors, covers and access panels
- Protection profiles for contact edges and transition areas
- Industrial equipment sealing and vibration reduction
- Custom sealing solutions requiring a non-standard triangular cross-section
Installation
Install the silicone triangle seal strip on a clean, dry surface to ensure reliable contact.
For adhesive-backed versions, remove the protective liner and apply firm pressure along the installation surface. For compression applications, select a profile size that provides suitable deformation without excessive compression.
For mechanical fixing or custom assembly requirements, the profile can be cut, bonded or integrated according to the application design.
Custom Options
Custom colors, lengths and profiles available upon request.
SealsHub can provide OEM silicone triangle seal strips with customized dimensions, hardness, surface finish and profile designs to meet specific sealing requirements.
FAQ
Q: What is the difference between a concave triangle seal strip and a standard triangle seal strip?
A: The concave triangle seal strip features an inward curved slope surface, which changes the contact area and compression behavior. This design can improve adaptability when sealing corners, uneven surfaces or transition areas.
Q: What is the advantage of a concave triangle profile design?
A: The inward curved structure reduces unnecessary profile volume, improves space efficiency and provides flexible compression behavior while maintaining reliable sealing performance.
Q: Is this profile suitable for outdoor applications?
A: Yes. Solid silicone rubber provides excellent resistance to weathering, UV exposure, ozone and temperature changes, making it suitable for many indoor and outdoor sealing applications.
Q: Can the silicone triangle seal strip be customized?
A: Yes. SealsHub supplies custom silicone profiles with different dimensions, hardness levels, colors and cross-section designs based on customer requirements.
Q: Can this profile be supplied in continuous lengths?
A: Yes. The seal strip can be supplied in continuous lengths or customized cut sections depending on the application needs.
