Acorn Sealing Nuts

ZAGO’s Acorn Sealing Nuts offer reliable protection and environmental sealing where ordinary nuts fall short. Each fastener integrates a custom-engineered, chemically resistant rubber O-ring that sits in a special groove. Once installed, the O-ring fills the groove, forming a 360-degree barrier against air, liquid, gas, dust and a host of contaminants. This unified design eliminates the need for additional washers, gaskets, or sealants. The result: fewer parts, improved protection and faster assembly.

Available in Low and High Crown profiles, ZAGO’s Acorn Sealing Nuts protect and prolong the life of critical systems in a sleek, reliable and reusable design. ZAGO’s fasteners are proven in demanding applications like flight-critical hardware, diagnostic devices and aerospace electronics.

All components are fully customizable (see detail below) and engineered-to-order to ensure optimal performance. ZAGO’s team of US-based engineers is available to share their expertise and help make the best choice.
