Office Chair Hydraulic Parts
Office chair hydraulic parts mainly include gas springs (hydraulic rods), cylinders, etc. Among them, the gas spring is the core component. When it fails, it can be replaced. There are various specifications and types, and there are certain methods for replacement.

Core Parts and Their Functions
The gas spring is a key component for the height adjustment function of an office chair. It regulates the height of the office chair through internal pressure changes, allowing users to adjust to a suitable sitting height according to their needs and enhancing comfort. When the gas spring has issues, such as an inability to rebound (i.e., the chair cannot automatically return to its original height after pressing the adjustment button) or sinking (the chair descends uncontrollably), these situations will affect the normal use of the office chair, and it will be necessary to consider replacing the gas spring.
Specifications, Types, and Prices
Gas springs come in various specifications and types. A common type is the four-stage sinking hydraulic rod. This specification provides relatively stable height adjustment and has a certain sinking characteristic, suitable for office chairs with high requirements for height adjustment stability, such as gaming chairs. The price of a four-stage sinking hydraulic rod starts at 131.00 yuan. There are also four-stage explosion-proof gas springs. The explosion-proof design enhances safety during use, preventing the gas spring from exploding due to abnormal pressure. The prices of Hengkang four-stage explosion-proof gas springs include different transaction prices such as 20.38 yuan and 20.9 yuan. Additionally, the prices of explosion-proof height-adjustable gas spring accessories vary, with different transaction situations such as 9.0 yuan and 25.0 yuan, and prices may fluctuate depending on the specifications and merchants.
Replacement Method
Replacing the gas spring on some office chairs is relatively simple and does not require removing screws. During the specific operation, first step on the bottom of the office chair, and then loosen the connection between the gas spring and other parts of the chair by shaking. You can also gently tap the circular area around the gas spring to further separate it. Once the gas spring is loose, you can remove it and install a newly purchased gas spring of the same specification. In this way, the height adjustment function of the office chair can be restored to normal use.
