316 stainless steel marine gas struts provides the high cleanliness and corrosion resistance required for seawater applications or in the marine, medical, chemical, and food service industries. Standard marine gas struts have fixed force levels. Marine gas struts and marine gas springs are best suited for applications that require the same force output for each cycle. If an application requires a specific force, Gastac will custom manufacture boat gas struts that are perfectly suited to your application.

How does A Compression Gas Strut Work?
As the name suggests, these gas springs rely on pressured gas – along with some oil-based lubricant – to support or oppose a range of external forces. The compressed gas offers a controlled way of storing and releasing energy as smooth, cushioned movement, transferred via a sliding piston rod.

What Is the Problem with Gas Struts?
Gas struts can experience common problems such as loss of pressure, making them weak or unresponsive; partial rusting, especially in humid conditions; fluid leakage, reducing hydraulic performance; and damaged seals, causing malfunction or safety risks. Regular inspection and timely replacement ensure reliable operation.
- Loss of Pressure → Gas struts losing pressure and failing to function properly
- Partially Rusted → Stainless steel surfaces showing partial rust and corrosion
- Leaking Fluid → Hydraulic fluid leaking from the gas strut cylinder or seal
- Damaged Seal → Seals inside the gas strut damaged, causing malfunction or leaks

How to choose a gas spring that can replace the damaged one?
If you are looking to replace your old gas struts, use our Gastac website search engine to allow you to find one-on-one replacements for the current gas struts you need. To use the tool, you simply fill in the item number (section) on the pillar, and a product page of the same specification will appear. Click here to try to find boat hatch gas struts.
If no results are displayed, you can configure the replacement gas strut yourself, but this is only recommended if you know all the important indicators (e.g. required force in Newtons).
Another approach is to completely recalculate the marine gas springs application for the cabin door. In this case, you will need to provide all the necessary information about the cabin door, such as weight, dimensions, opening/closing angles, etc. Our professionals will calculate and give you the most suitable advice.
How to Install Gas Struts on A Boat?
Attach brackets to boat and mounting points on the strut. Extend the strut to the desired opening angle, then align the bracket on the boat and mark holes. Drill and secure brackets with stainless steel fasteners. Repeat on the other side, ensuring struts are parallel for smooth operation.
