      Works great

      Posted by Unknown on 25th Apr 2020

      Purchased this cylinder in October 2019. Half a year later it is still working great. No complaints! Great product! I used a pipe wrench, PB Blaster, and elbow grease to remove the old cylinder.

      It works well - GC-4 Heavy Duty office Chair Pneumatic Gas Cylinder

      Posted by Steve on 14th May 2017

      Used to replace the failed Gas Cylinders in my poker table chairs. A drop-in replacement used in conjunction with SP-686 Replacement Chair Mechanism Seat Plate With 6" x 8.6" Mounting Holes.

      I am very happy with the part and have it in the chair now. I do not feel like I am sitting on the floor but up in the sky

      Exceeds the specifications, excellent product

      Posted by John Matysek on 21st Jul 2016

      The replacement part exceeds the original part on my office chair. In using my chair after the installation of the replacement part, there is a remarkable and positive difference in performance. Great service and prompt shipping. Thanks for your customer support.
