The 081492 gas spring from Ressorts SPEC is purpose-built for marine service where salt, spray, and vibration demand rugged reliability. It combines a nitrided black carbon steel shaft with plastic ball bushing end fittings, delivering robust lifting support with controlled motion while keeping weight and cost in check.
With a total extended length of 609 mm including end fittings, a stroke of 250 mm, and a substantial 800 Newtons of force, this strut is ideal for heavier lids and deck gear. Corrosion resistance is validated to the ASTM B117 salt spray standard; the SPD™ corrosion-resistant line offered in stainless steel is tested to 500 hours of continuous exposure, underscoring its suitability in harsh marine atmospheres.
Typical onboard uses include engine box lids, large cockpit lockers, tender garages, and other applications where a powerful, predictable gas strut improves safety and handling during sea motion (pitch and roll).
Specifications
- Material: Nitrided black carbon steel shaft with plastic ball bushing end fittings.
- Force: 800N – high assistance for heavier marine applications.
- Stroke: 250 mm for controlled extension and closing dampening.
- Total length with end fittings: 609 mm.
- Total length without end fittings (body length): 549 mm.
- Compressed length without end fittings: 299 mm (549 mm − 250 mm).
- Corrosion resistance: Tested per ASTM B117; SPD™ stainless line benchmarked to 500h salt spray.
- End fittings: Plastic ball bushings for quick, secure snap-on mounting to ball studs.
Installation / Maintenance
Installation
The plastic ball bushing ends snap onto compatible ball studs for rapid, secure fitment—ideal where access is limited. Confirm mounting geometry (center-to-center at full open) and orientation (rod-down in service where possible) to maximize seal life and damping control.
Maintenance
Rinse with fresh water after exposure to seawater. Periodically apply silicone spray or marine-grade lanolin to joints and check fasteners/hinges for play or corrosion. Do not paint the rod; avoid clamp marks on the shaft.
Compatibility
Installed on Jeanneau and Beneteau sailing yachts and motorboats.
Our review
✔ Pros
- High thrust (800N) for heavy lids, engine covers, and large lockers.
- Nitrided shaft resists wear and corrosion in a marine environment.
- ASTM B117 salt spray validation; SPD™ stainless line tested to 500h.
- Plastic ball bushings simplify installation and minimize weight.
✘ Cons
- Carbon steel is less corrosion-resistant than full 316L stainless versions.
- Plastic ends are not as mechanically robust as stainless or alloy fittings.
Conclusion
The 081492 gas spring is a powerful, cost-effective choice for Bénéteau and Jeanneau yachts where heavy hatches demand dependable lift and damping. If maximum corrosion resistance is your priority, consider an all-stainless variant; otherwise, this nitrided carbon steel model offers excellent value and performance for demanding onboard service.
Good to Know
- Match extended length, stroke, and force to your original part before replacement.
- Install rod-down when possible to keep the internal seal lubricated and extend service life.
- Reference corrosion testing per ASTM B117 for marine durability expectations.
