About Self-Sealing Nuts

Self Sealing Nuts

The Idea

In cases of severe pressure, ZaGO’s self-sealing nuts and plugs offer the ultimate sealing protection. ZaGO’s self-sealing nuts can withstand extreme conditions thanks to their unique design which features a rubber layer on the face of the nut. ZaGO’s seal nuts include a built-in “O” ring which has the power to seal in/out elements. We manufacture self-sealing nuts which are compatible with different types of environments. If you’re working in high pressure circumstances, then your equipment demands the best quality self-sealing nuts and plugs. Our self-sealing nuts may be installed just like any other nuts and plugs, but, in terms of functionality, they are far from ordinary pieces of hardware.

How It Works

ZaGO’s one piece self-sealing nuts and plugs offer superb fastening and sealing power in metal-to-metal contact. They block air, liquid, dust and other contaminants with a special defensive rubber. When you apply torque onto the nut, the subsequent three-way tensioning effect creates a 360 degree water-tight seal about the nut.

Special Features include:

  • Sealing water/moisture, air, dust, liquids, and other contaminants either in or out through the thread or bearing face
  • Reducing noise and vibration
  • Do not require any special installation
  • Metal-to-metal contact
  • No maintenance/re-tightening needed
  • Customizability
  • Reusability

The Results

ZaGO’s self-sealing nuts and plugs are dependably resistant against the chemical and environmental elements ordinary nuts and plugs simply don’t stand a chance against. They are user-friendly, cost-effective and environmentally sustainable solutions to any challenge you may face in the field, in the water, in the operating room, and beyond. Our Engineers are always happy to work with you as you select the best materials for your individual needs.
