Specs At A Glance

Good To Know

Q: How do I confirm this seal kit matches my lift model? A: Check the model plate on your rotary lift to verify it falls within the SPOA7-300 to -700 series, and cross reference your existing part number against N342-12, N343, or N346.

Q: What causes hydraulic cylinder seal failure on lifts? A: Normal wear, contamination, or overheating can degrade seals, leading to fluid leaks and reduced lifting force. Replacing with this kit restores proper sealing and performance.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
