Gas struts, also known as gas springs or gas shocks, play a role in our everyday lives, from helping us open car boot lids to smoothly adjusting office chairs. Knowing how to compress a gas strut safely and effectively can make a big difference when it comes to installation, maintenance, or even disposal. This guide will walk you through everything you need to know in simple, clear terms.
What is a gas strut?
A gas strut is a device that uses compressed gas to provide support and motion. It consists of a piston, a cylinder, and gas (usually nitrogen), which creates pressure to balance or counteract weight. You’ll often find them in cars, kitchen cabinets, and industrial machinery.
Why might you need to compress a gas strut?
Compressing a gas strut is sometimes necessary for a range of tasks, such as:
- Installing a new strut: some struts need to be compressed to fit them into place.
- Checking for issues: testing the strut to ensure it’s working properly.
- Tailoring it to specific needs: adjusting the strut for a custom setup.
- Disposing safely: releasing pressure before getting rid of it.
How to compress a gas strut: step-by-step instructions
Step 1: secure the strut
Start by placing the gas strut in a vice or clamp. Use soft grip pads to protect the surface and make sure it’s held firmly in place so it won’t slip.
Step 2: locate the piston end
Gas struts have two main parts: the cylinder and the piston rod. The piston rod is the part you’ll need to push into the cylinder.
Step 3: apply steady pressure
Use your hands or a tool to apply steady, even pressure to the piston rod. Slowly push it into the cylinder. Avoid any sudden movements that could damage the mechanism.
Step 4: use a spanner for extra leverage
If the rod doesn’t move easily, try using an adjustable spanner for extra leverage. Position it on the collar of the rod and press firmly but carefully. Avoid twisting the rod to prevent damage.
Step 5: add lubricant if needed
For older or stubborn struts, applying a little lubricant around the piston rod can help. Give it a few minutes to work before trying again.
Step 6: test and repeat
Once you’ve compressed the rod partially, release it slowly to test its resistance. Repeat the process until you achieve the desired compression.
Troubleshooting common issues
- The rod won’t move
What to do: check if the strut is secured properly and apply steady pressure. Lubricant can also help loosen it. - Gas leakage
How to solve this: if you notice gas escaping, the strut is likely damaged and should be replaced immediately. - It’s too stiff
What to do: some struts have adjustable valves. Refer to the manufacturer’s instructions to reduce internal pressure.
When should you call in a professional?
If you’re unsure about handling a gas strut or if it’s part of a critical system like medical equipment, it’s best to seek professional help. Experts have the right tools and know how to handle high-pressure struts safely and effectively.
