Sealing Blind Rivet | Reliable Fastening and Sealing in One Step
The Sealing Blind Rivet is an industrial fastening solution designed to provide both secure fastening and reliable hole sealing in a single installation. Unlike standard open-end blind rivets, its sealed sleeve structure is designed to close the installation hole after setting, helping reduce the risk of water, oil, coolant, or air leakage. Since installation can be completed entirely from one side of the workpiece, it is particularly suitable for enclosed tubes, thin-wall structures, confined spaces, and applications where access to the rear side is limited.
During installation, a riveting tool applies a controlled pulling force to the rivet, causing the sleeve to expand and form a tight seal against the hole wall. The fully annealed aluminium sleeve provides excellent deformation capability, helping improve hole filling and sealing performance. Its ability to accommodate a relatively wide range of hole tolerances also simplifies assembly and reduces the impact of minor variations in hole diameter. In addition, the robust setting structure provides good resistance to vibration, making it suitable for demanding industrial environments.
Key Product Features
• One-side blind installation – Ideal for enclosed structures and applications with limited rear-side access.
• Fastening and sealing in one step – Secures the components while effectively closing the installation hole.
• High sealing performance – The fully annealed aluminium sleeve can support working pressures of up to approximately 300 bar (4,350 psi), depending on application conditions.
• Wide hole tolerance capability – Excellent hole-filling characteristics help maintain reliable sealing despite variations in hole diameter.
• Vibration resistance – Suitable for automotive, machinery, and industrial equipment exposed to continuous vibration.
• Efficient installation – Compatible with manual, pneumatic, battery-powered, and automated riveting systems.
Technical Highlights
The standard sleeve is manufactured from 6061 aluminium alloy, while the rivet is made from medium carbon steel with hardened and tempered treatment, followed by zinc plating and clear trivalent passivation. A range of standard sizes is available to accommodate different hole diameters, material thicknesses, and sealing requirements. Customized designs can also be developed according to specific application requirements, including dimensions, materials, pressure conditions, and assembly requirements.
Typical Applications
Sealing Blind Rivets are widely used in automotive components, engines, transmissions, hydraulic and pneumatic equipment, cylinders, compressors, pumps, machinery, and electronic equipment where water, oil, coolant, or air sealing is required.
They are especially valuable for thin-wall castings, short-depth holes, enclosed structures, larger hole tolerances, and applications where conventional bolts or nuts are difficult to install. By combining fastening, sealing, one-side installation, and production efficiency, the Sealing Blind Rivet provides manufacturers and procurement teams with a practical, cost-effective solution for demanding industrial assembly applications.
