WORKPRO Gas Cylinder Kit

No, this is an oversized cylinder designed specifically for the Workpro 15000 model. It features a 2.5-inch column width, which is wider than standard office chair cylinders, so it will not fit most universal chair bases.

You likely need a replacement if your chair slowly sinks while you are sitting in it, if the height adjustment lever no longer responds, or if the chair feels unstable and wobbly. These are clear signs that the pneumatic seal inside the cylinder has failed.

You will generally need a pipe wrench or a rubber mallet to remove the old cylinder from the chair base and the seat mechanism. A penetrating oil, like WD-40, can also be helpful if the old cylinder is stuck due to years of use.

This cylinder offers a 3.5-inch stroke, which is designed to restore the original height adjustment range of the Workpro 15000. It is built to match the factory specifications, not to alter the chair's height beyond its intended design.

Yes, this cylinder is engineered with heavy-duty construction to support up to 500 lbs. It is specifically built for high-capacity seating requirements, ensuring stability and safety for heavier loads that standard cylinders cannot provide.
