A gas spring stuck in the open position can be more than just an annoyance, it can be a safety risk or even halt your project altogether. Whether you’re working with hatches, cabinets, windows, or industrial equipment, a malfunctioning gas spring can seriously disrupt operations. In this guide, we’ll walk you through the most common causes of a gas spring being stuck open, how to fix or replace it, and which tools can help you find the perfect replacement or alternative.
Why is my gas spring stuck open?
Gas springs, also known as gas struts, operate under high internal pressure using nitrogen gas and oil. When they’re stuck open, it often means that the internal pressure has changed or a component inside the cylinder is no longer working properly. Here are a few common reasons this might happen:
- Internal gas leakage or pressure loss
- Oil seal failure, preventing proper retraction
- Corrosion or debris inside the cylinder
- Incorrect mounting or installation angle
- General wear and tear over time
If you notice your gas spring no longer retracts or stays extended without force, it’s time to inspect it carefully, or replace it altogether.
When is it time to replace a stuck gas spring?
Gas springs can usually be compressed by hand only with some resistance. If yours is stuck in the open position and you can’t move it at all, this is a red flag. Especially in safety-critical applications, like hatches or heavy lids. A stuck gas spring should be replaced as soon as possible.

How to prevent your gas spring from getting stuck open
Prevention is always better than repair. Here’s what you can do to extend the lifespan of your gas springs and avoid them getting stuck:
Keep the piston rod clean and free of dust or grease. Avoid placing the gas spring rod-up in vertical applications, this may cause the oil to shift away from the seal, leading to failure over time. We always recommend installing your gas spring rod-down and at an angle of no more than 60 degrees from vertical.
And don’t forget: overuse, incorrect mounting, or simply ageing can reduce performance. If your gas spring has exceeded 40,000 cycles, it’s likely time for a replacement.

Real-life example: A gas spring failure in a workshop
We once had a customer with a boat hatch gas spring that had been stuck open for weeks. It was a stainless steel model exposed to saltwater, and the internal seals had corroded. Using the product code, they entered it into our replacement tool and found a match in less than a minute. Within 2 days, they had a new gas spring installed and working, safe and smooth as ever.
This kind of thing happens more often than you’d expect, especially in environments with humidity, dust, or inconsistent mounting.
Should I try to fix a stuck gas spring?
Short answer: no. Gas springs are sealed, high-pressure systems. Trying to open or repair one can be dangerous and usually voids warranties. We strongly recommend replacing it rather than attempting DIY fixes.
