What are Sealing Fasteners?

360º seal eliminates seepage – in or out

Sealing fasteners are highly specialized fasteners that include sealing screws, sealing nuts, sealing bolts and sealing washers. Unlike ordinary fasteners, sealing fasteners are configured with a rubber O-ring (or a rubber element) that when squeezed, permanently seal out a wide range of contaminants from entering and damaging equipment while preventing leakage of toxins into the environment.

The Difference

ZAGO high-tech self-sealing fasteners are engineered with a groove under the head of the screw or the face of the nut that when combined with a rubber O-ring and tightened, squeezes outwardly to form a 360-degree leak-proof hermetic seal. The undercut groove ensures that the O-ring will not break or crack once the screw is torqued, and the metal-to-metal contact prolongs the life of the O-ring, which is not compromised under pressure.

Sealing Fasteners for All Seasons

ZAGO sealing fasteners are designed to withstand harsh weather and extreme temperatures, such as when unmanned underwater vehicles survey the icy cold depths of the ocean floor to unmanned automotive vehicles operating in the extreme heat of the desert. They are vibration and pressure-resistant and outperform ordinary fasteners in highly pressurized environments, such as pneumatic pumps used in medical ventilators and pressure valves in industrial machinery.

When to Use ZAGO Sealing Fasteners - Key Questions

If the answer is yes to any of the following questions, then, it is essential to seal your equipment with sealing fasteners for long-lasting, air-tight, leak-proof protection:

Does your high-asset machinery / sensitive equipment need an air-tight, hermetic seal to:

Protect itself from exposure to oil, gases, liquids, chemicals, dust, dirt, moisture, salt water or other contaminants?
Withstand extreme pressure, temperature and/or weather conditions?
Prevent seepage of pollutants leaking into the environment?
