How It Works

ZAGO high-tech sealing nuts are configured to bond with a rubber element, such as Silicone, Fluoro-silicone, Buna-N, and Viton, that when tightened to required torque value, squeezes outwardly and upon metal-to-metal contact, provides a 360 degree air-tight seal inside the thread as well as the circumference of the nut. This hermetic seal prevents airflow leakage, such as between pipe fittings or in a pneumatic pump , while blocking contaminants, like dust, moisture, oil, liquids, and gas, from entering and damaging high-asset equipment or leaking into and harming the environment. ZAGO sealing nuts are small yet tough enough to withstand extreme pressure, temperature and weather conditions, resist vibration and reduce noise.

ZAGO one-unit sealing nuts, available in hex, hex flange, acorn nut, and large pipe threading sealing nuts, are reusable and eliminate the need for sealing washers. They protect and prolong the lifespan of industrial machinery, factory automation equipment, power tools, hydraulic control systems and pressure valves.

ZAGO offers metric, inches and pipe threading options for nuts in a variety of materials, like steel, stainless steel, titanium, aluminum and copper, and a rubber element that meets Military Spec AS568. Food and medical-grade compliant rubber and DFARS parts are available upon request.
