The Secret to Enhanced Sealing and Strength — A Complete Guide to Sealing Blind Rivets
What is a Sealing Blind Rivet?
Sealing blind rivets are fasteners designed specifically for sealing applications, enabling efficient and reliable fastening with one-sided access.
They are typically composed of an aluminum sleeve (6061 aluminum alloy) and a hardened and annealed medium-carbon steel mandrel, treated with zinc plating for enhanced corrosion resistance.
Key Features of Sealing Blind Rivets
1. Outstanding Sealing Performance
The fully annealed aluminum sleeve design allows the rivet to maintain excellent sealing even under working pressures up to 300 bar (around 4,350 psi),
effectively preventing the leakage of water, oil, or gas.
2. Easy Installation
Sealing blind rivets require no special hole preparation or tapping — they can be installed directly into standard drilled holes.
They are compatible with manual, pneumatic, electric, or automated installation tools, greatly improving installation efficiency.
3. High Adaptability and Vibration Resistance
Their design tolerates larger hole diameters, simplifies automatic alignment, and provides strong hole-plugging capabilities with high vibration resistance,
making them ideal for a wide range of industrial applications.
Application Scenarios
Sealing blind rivets are widely used in environments requiring both sealing and fastening. Typical applications include:
Automotive and Aerospace Industries: Connecting thin metal sheets or composite materials while maintaining structural strength and reducing weight.
Machinery and Electronics: Fastening internal structures to enhance equipment stability and durability.
Architecture and Interior Design: Fixing construction materials such as aluminum doors, windows, and ceiling panels, offering both strength and aesthetics.
Marine and Waterproof Applications: Essential for shipbuilding and other areas requiring watertight connections to ensure structural sealing.
Why Choose Sealing Blind Rivets?
Choosing sealing blind rivets is driven by their advantages in sealing performance, ease of installation, and high adaptability.
Whether in high-pressure environments or situations demanding installation efficiency and reliability, sealing blind rivets provide a stable and effective fastening solution.
