Understanding Gas Strut Functionality
Gas struts are essential components in various applications, from vehicle hatches to furniture. They provide controlled movement and support for opening and closing objects. However, like any mechanical part, gas struts can wear out over time, leading to decreased performance or complete failure.
Signs of Gas Strut Deterioration
Before considering repair options, it’s crucial to recognize the symptoms of failing gas struts:
• Difficulty in opening or closing the supported object
• Uneven movement or sudden drops
• Visible oil leakage around the piston
• Squeaking or hissing noises during operation
Can Gas Struts Be Repaired?
The short answer is yes, gas struts can often be repaired through a process called re-gassing. This involves repressurizing the strut with nitrogen gas to restore its functionality. However, the feasibility and cost-effectiveness of repair depend on several factors:
• Age of the strut
• Extent of wear or damage
• Availability of specialized equipment
The Re-gassing Process
Re-gassing a gas strut typically involves the following steps:
Removal of the strut from the host equipment
Professional inspection to assess repair viability
Depressurization and cleaning of the strut
Refilling with nitrogen gas to the correct pressure
Testing for proper function
Reinstallation on the host equipment
It’s important to note that this process requires specialized tools and expertise, making it unsuitable for DIY attempts.
When to Consider Replacement Instead of Repair
While re-gassing can be an effective solution, there are instances where replacement is the better option:
• Visible physical damage to the strut body
• Extensive seal deterioration
• Age exceeding 8-10 years
• Cost of repair approaching that of a new strut
Professional Repair Services
Many companies offer gas strut repair services. The process typically involves:
Sending the strut to a specialized workshop
Free inspection to determine repair feasibility
Quote provision for repair or replacement
Same-day testing and re-gassing if approved
Rapid return shipping of the repaired strut
DIY Temporary Solutions
While professional repair is recommended, there are temporary DIY fixes for emergency situations:
• Using a wooden dowel or PVC pipe as a support
• Applying locking pliers to hold the strut in place
• Installing aftermarket universal gas struts
These solutions should only be used as short-term measures until proper repair or replacement can be arranged.
Preventive Maintenance for Gas Struts
To extend the life of your gas struts and potentially avoid the need for repairs:
• Keep struts clean and free from debris
• Avoid overloading beyond their rated capacity
• Protect from extreme temperatures when possible
• Lubricate attachment points periodically
