Product description

A small but critical component, this O-ring is the primary sealing element for dielectric unions in Rotary lift systems. It is specifically designed to prevent hydraulic fluid or air from bypassing the union while maintaining the electrical isolation required in many inground installations. Over time, exposure to temperature fluctuations and hydraulic oils can cause the original rubber to become brittle or misshapen, leading to persistent leaks. Replacing a worn O-ring with this SVI International part ensures a tight, professional seal and protects your lift from the effects of electrolysis. It is an inexpensive way to prevent costly fluid loss and maintain the longevity of your hydraulic connections.

Product highlights

• High-Performance Elastomer: Resistant to hydraulic fluids, oils, and environmental degradation for a longer service life.
• Precision Sealing: Engineered to provide a perfect airtight and watertight seal within the dielectric union.
• Critical Isolation: Supports the dielectric function of the union to prevent galvanic corrosion in underground pipes.
• Exact Fit: Designed as a direct replacement for the O-ring used in the Rotary FA538-9 union assembly.
