Maintaining a perfect seal in your Weaver in-ground lift requires consistent outward pressure against the cylinder packing. This SVI International 7-1/2" packing expander is a critical component for lifts using the A-1325 series plunger. It sits inside the packing assembly, ensuring that the seal remains tight against the plunger surface to prevent hydraulic fluid leaks. Over years of service, expanders can become warped or lose their tension, leading to "creeping" or fluid loss. This SVI replacement is manufactured to precise tolerances to restore the original sealing performance of your Weaver lift. It is an essential part for any full seal replacement or cylinder overhaul.
