Frequently Asked Questions

Q: What type of hydraulic jack is this oil seal repair kit compatible with?

A: This repair kit is specifically designed for horizontal 3-ton rocker/floor jacks. It includes seals for the plunger, piston, ball link, and O-ring components. Please compare the included parts with your jack's existing seals (as shown in the product images) to confirm fitment before purchasing.

Q: How do I know if my hydraulic jack needs new oil seals?

Replacing the oil seals and O-rings with this repair kit is often all that's needed to restore full function.

A: Yes! This kit is designed to be accessible for both DIY home mechanics and professional technicians. Basic mechanical knowledge and the right tools are recommended. Always depressurize the jack completely and follow safe workshop practices before beginning any repairs.
