Usa Industrials ZUSAS70FDA013 Silicone O-ring Dash 013

Product Description

The USA INDUSTRIALS ZUSAS70FDA013 is a silicone O-ring with a round cross section, designed for static and dynamic sealing applications across a wide temperature range. With an inside diameter of 0.426 inches, an outside diameter of 0.566 inches, and a thickness of 0.070 inches, this Dash 013 O-ring is molded to Shore 70A hardness and rated for continuous service from -80 degrees F to 450 degrees F. It meets FDA, 3A, and ASTM 568 standards, making it suitable for food-processing, pharmaceutical, and sanitary piping systems where material compliance is required. The red color aids visual identification during maintenance and inspection.

This O-ring is used in plumbing, HVAC, and industrial fluid-handling applications that demand good dry heat resistance and broad temperature tolerance. It performs well in environments with exposure to weather and ozone, and offers limited resistance to oils, chemicals, and solvents. It is a common choice for sanitary fittings, process piping, and equipment seals where FDA-compliant elastomers are specified. Licensed plumbers, pipefitters, and maintenance technicians typically source this size for repair and replacement work on valves, fittings, and mechanical connections.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or maintenance technician. Depressurize and drain the system completely before removing the existing O-ring. Inspect the groove for burrs or damage before seating the new ring. Avoid overstretching during installation, and do not use petroleum-based lubricants with silicone O-rings unless confirmed compatible with the system fluid.
