The 081635 gas spring from Ressorts SPEC is a high-force, corrosion-resistant marine strut engineered for demanding onboard applications. With a powerful 300 Newton output and a 250 mm stroke, this model is designed to lift heavier components such as deck hatches or engine covers, even under challenging marine conditions.
Manufactured using nitrided carbon steel (black GSNI SPEC finish) and equipped with plastic ball bushing end fittings, this gas spring combines solid structural integrity with resistance to marine corrosion. Though not stainless steel, it has been tested to 500 hours of salt spray according to the ASTM B117 standard, ensuring durability in coastal and offshore environments.
Specifications
- Material: Nitrided black carbon steel shaft (GSNI SPEC) with plastic ball bushings
- Force: 300N – ideal for heavy-duty hatch lifting and structural panels
- Stroke: 250 mm – allows extended hatch opening range
- Total length with end fittings: 585 mm
- Gas spring body (excluding end fittings): 549 mm
- End fittings: Plastic ball bushings – corrosion-resistant, snap-on design
Installation / Maintenance
Installation
The 081635 features snap-on plastic ball bushings for fast, tool-free installation on standard marine ball studs. Its strength and length make it especially suitable for center cockpit hatch lifts and similar onboard mechanisms requiring significant force, such as on the Beneteau 8.8 Flyer Sundeck.
Maintenance
After each use in saltwater conditions, rinse with fresh water to prevent corrosion. Apply silicone spray or marine-grade lanolin to moving joints and clevis points to maintain smooth performance and extend service life.
Compatibility
Commonly found on Beneteau and Jeanneau vessels, including the Beneteau 8.8 Flyer Sundeck (center cockpit hatch). Also suitable for other marine applications where greater lifting power is needed.
