Hydraulic Chairs are widely used because of the comfort and compatibility they offer. We can adjust them as per our preference and use them accordingly.
They are also really comfortable to use and offer tremendous relief to our backs. These chairs are a great way to improve our posture and get rid of problems caused by bad posture.
And due to its sleek and beautiful design, they also give a luxurious and modern look. Being equipped with wheels, these chairs are easy to move.
Due to the complex hydraulic chair mechanism, these chairs can easily get damaged if we don’t take proper care of them. And buying a new hydraulic chair again is a really expensive thing to do. So in this article, we will tell you about how to fix a Hydraulic Chair.
Why Do Hydraulic Chairs Get Damaged?
Although, in other circumstances, the hydraulic chair will stop working because it has become old, rusted, and worn out due to regular use. Aside from that, another probable cause is that the cylinder is no longer operational.
A pneumatic cylinder in office chairs controls the chair’s height with compressed air. Standard hydraulic chairs are controlled by a hydraulic chair lift mechanism, such as a lever or valve, that allows you to move up and down based on the correct desk height or comfortability.
Most chairs’ cylinders break after a few years, usually because the seals have become too corroded to retain pressure. To restore complete functionality to your chair, you can purchase a replacement cylinder, but this is nearly as expensive as purchasing a new chair.
So here are some tricks that you can use to repair or fix your hydraulic chair.
Steps Of How To Fix Hydraulic Chair?
Greasing The Surface
You should properly inspect the chair’s hydraulic cylinder and other mechanical components. If you see indicators of friction when using the chair, it is likely that it is lacking in oil.
To keep the components from sinking, you’ll need to oil them. You should start with the lever. When using your hydraulic chair, see if it can control your desired height.
If it sinks to the bottom and stays there, it merely signifies it requires lubrication to function.
Moisture and air conditioners are to blame for the corrosion. To avoid cranking sounds and sinking, apply a generous amount of oil on a regular basis.
- Using a hose clamp and duct tape
- A plastic tube covers the extensible cylinder in most office chairs. Drag this all the way to the bottom or all the way up until the metal cylinder underneath is visible.
- Because you won’t be able to modify the height after this repair, be sure it’s set correctly. When standing, the seat of the chair should be level with your knees.
- Wrap the cylinder with a hose clamp of 34” (2cm) that can be found very easily at a neighboring hardware store.
- Pull the belt end out by loosening the hose clamp screw. Tighten the clamp after wrapping it around the metal cylinder. To keep the chair in place, the clamp will have to be really tight.
- Wrap a strip of rubber or a couple thicknesses of duct tape around the cylinder to provide the clamp a greater gripping surface. Do this at the cylinder’s highest visible point. Slide the hose clamp to the cylinder’s top.
- Squeeze the hose clamp tightly and tighten the screw to secure it. The clasp should now prevent the chair from sliding down past it.
- The built-in height adjustment will continue to malfunction. If the chair is too high or too low, raise or lower the clamp on the cylinder.
Replacing The Cylinder
If none of the other options worked, the best choice is to replace the hydraulic chair cylinder. It has a lengthy lifespan, and you may reap long-term benefits from it.
To avoid difficulties or further damage, you can have this process performed by a specialist from office chair repair near me. All you have to do now is get a high-quality, long-lasting cylinder.
The benefit of this method is that instead of a temporary height, you may adjust the chair’s height.
- Using a PVC pipe
- The extended metal cylinder is covered with a plastic skirt that can be pulled down. Hold a ruler horizontally across the cylinder to estimate its diameter. When the chair is at the ideal level, measure the length of the cylinder as well. Purchase a piece of PVC pipe.
- This pipe will fit over the chair’s pneumatic cylinder. It should be around the same size as or slightly larger than the cylinder diameter.
- Pipe with a diameter of 1.5 inches (3.8 cm) works well with most versions. When your chair is at the desired height, buy enough straight pipe to reach from the wheel base to the seat.
- It is not necessary for the pipe to be in one piece; smaller portions may be easier to deal with.
- Cut a lengthwise slit in the PVC pipe. In a vice, secure the pipe. Cut the pipe from tip to tip with a hacksaw or back saw, but only on one side. Instead of two half-pipes, the final product should be a pipe with a slit in it.
- If you don’t have a vise or cutting equipment, simply leave the pipe alone and remove the chair’s wheels to slide on it.
- In most situations, you may remove the wheel base by using a screwdriver to squeeze a retaining clip on the bottom.
- Attach the pipe to the cylinder of the chair. To uncover the metal cylinder, pull the chair’s plastic skirt up or down.
- Snap the PVC pipe around the cylinder by pressing the sliced side against the cylinder. It should now be able to keep the chair in position and prevent it from slipping down.
- If snapping the pipe on is proving difficult, cut it into smaller pieces and try again.
- To change the chair’s height, add extra pipe. If the chair is still too low, lift it and attach another piece of pipe to the back.
- You won’t be able to lower the chair without removing the pipe, so make sure it’s the right height the first time.
