Product description

This specialized Seal, Gland, and Spacer Kit is designed for the comprehensive overhaul of 8-1/2 inch Rotary in-ground cylinders. Unlike standard seal kits, this package includes precision spacers that help maintain the ideal alignment of the seal assembly against the plunger. This improved alignment reduces side-loading wear on the seals, which is a common cause of premature failure in older lift systems. By installing this SVI International kit, you are not just stopping a leak, but also addressing the underlying mechanical issues that lead to seal degradation. It is the ultimate choice for shops that want to minimize lift downtime and maximize the interval between hydraulic services. This direct-replacement kit provides a professional-level solution for maintaining 8-1/2" lifts.

Product highlights

• Enhanced Alignment: Includes critical spacers to ensure the seal and gland remain perfectly centered on the plunger.
• Reduced Wear: Prevents uneven seal loading, which significantly extends the service life of the hydraulic assembly.
• Premium Sealing Materials: Features high-grade polymers that maintain flexibility and sealing force over a wide temperature range.
• Proactive Maintenance: Ideal for restoring older cylinders where standard seal kits may fail due to minor alignment issues.
