Office chair cylinder removal kit

The BFKK kit supplies the tools needed to take out a worn gas lift and tilt control from a standard office chair. Two stainless-steel clamping shafts, two long bolts, two short bolts and an L wrench are included so the job can be finished without hunting for extra hardware. A printed manual walks through each step from start to finish. The set is aimed at anyone whose chair has started sinking and who wants to fix it at home.

Replaces improvised tool collections

Previously you might have tried to pry the cylinder loose with generic pliers or a hammer, risking damage to the base or the new cylinder. This kit replaces that approach with purpose-made clamping shafts and matched bolts that apply even force. The jump is worth it when the old cylinder is seized and you need a controlled removal that protects the chair frame.

Fits universal 28 mm cylinders

The clamping shafts are sized for the common 28 mm (1.1-inch) diameter found on most height-adjustable office chairs. No special power supply, socket or software is required — only the hand tools in the box. Once the old cylinder is out, the kit frees up the chair for a replacement cylinder or a fixed-height saver, letting you set the seat height you need in minutes.

Questions about this item

What diameter gas-lift cylinder does the 28 mm tool fit?

The kit is sized for 28 mm or 1.1 inch cylinders, which covers the standard height-adjustment posts found on most office chairs.

Which step do people most often miss when using the clamping shafts and bolts?

Users frequently forget to tighten both the long and short bolts evenly on the two stainless-steel clamping shafts before applying leverage, causing the cylinder to slip.

What part of the kit will need replacement after repeated cylinder removals?

The stainless-steel clamping shafts and bolts bear the pulling force; inspect them for thread wear or bending after several uses and replace if deformed.
