The 081647 gas spring from Ressorts SPEC is a cost-effective, marine-grade support strut designed for light-duty applications aboard sailboats and motorboats. Made with a nitrided black carbon steel shaft and equipped with plastic ball socket end fittings, it offers a lightweight yet sturdy solution for marine environments where full stainless steel is not required.
Its total length with end caps is 276 mm, with a core body length of 240 mm and a 100 mm stroke. The gas spring exerts a constant 100 Newtons of force, providing controlled support for hatches, locker lids, and other lightweight components. Though not fully stainless steel, this model is still tested against salt spray to the rigorous ASTM B117 corrosion standard.
Specifications

- Force: 100N – for light hatch and locker applications.
- Stroke: 100 mm for smooth and controlled motion.
- Total length with end fittings: 276 mm.

- Corrosion resistance: Salt spray tested (ASTM B117 – 500h).
Installation / Maintenance
Installation
This model features plastic ball socket ends that allow for quick and secure installation on standard 10 mm marine ball studs. Its compact design makes it ideal for confined spaces, such as cockpit lockers, engine bay covers, or internal cabinetry.
Maintenance
While the nitrided coating adds surface protection, it’s recommended to rinse the gas spring with fresh water after exposure to seawater. Regular application of silicone spray or marine lubricant can help preserve the internal seals and ensure long-lasting performance.
Compatibility
This gas spring is commonly found on Jeanneau and Beneteau vessels. It can be used as a budget-friendly alternative to stainless steel models in protected or semi-protected areas aboard.
Our review
✔ Pros
- More affordable than full stainless steel models.
- Nitrided black carbon steel offers decent corrosion resistance.
- Lightweight plastic ends simplify installation.
- ASTM B117 salt spray tested (500h).
✘ Cons
- Less resistant to long-term saltwater exposure than 316L stainless steel.
- Plastic end fittings not suitable for high-load applications.
Conclusion
The 081647 gas spring is a smart option for boaters seeking an economical yet reliable solution for small marine hatches or panels. While it does not offer the full corrosion resistance of stainless steel models, its nitrided black finish and ASTM B117 compliance make it suitable for protected marine environments. Ideal for Bénéteau and Jeanneau vessels in light-duty use cases.
Good to Know
- Check that your original strut matches the 276 mm length and 100N force before replacing.
- Not recommended for constant salt spray exposure—use in semi-sheltered or interior compartments.
- Fits 10 mm ball studs as used on most BJT (Beneteau & Jeanneau) boat models.
