GT Omega Piston

The Short piston is designed for users who need a lower seat height or have a shorter stature, while the Regular size is the standard height included with most GT Omega chairs. Choose the size that matches your current setup or your specific ergonomic height requirements.

This piston is specifically engineered for GT Omega chair bases and mechanisms. While it may fit other brands with similar standards, we recommend it primarily for GT Omega products to ensure proper fit and safety.

A Class 4 piston offers superior durability and weight-bearing capacity compared to lower-class alternatives. It also provides enhanced shock absorption, which helps maintain the ergonomic comfort and stability of your chair over time.

Yes, if your chair is losing height while you are sitting in it, the internal seal of your current piston has likely failed. Replacing it with a new Class 4 piston will restore the chair's ability to hold its height position.

You will generally need a rubber mallet and a pipe wrench to remove the old piston from the chair base and the seat mechanism. The installation itself is straightforward, but removing a seized, older piston can require some force.
