TruDesign Ball Valve Spanner – Composite Installation Tool for Marine Valves

Install your marine plumbing components with confidence using the TruDesign Ball Valve Spanner—a purpose-built installation tool designed specifically for TruDesign ball valves.

Engineered in New Zealand from glass-reinforced nylon composite, this spanner is lightweight yet extremely strong, providing the perfect balance of control and durability during installation. It is completely corrosion and electrolysis free, making it ideal for long-term use in harsh marine environments.

Unlike generic tools, the TruDesign spanner is precision-matched to the flats on TruDesign ball valves, allowing for accurate tightening without damaging threads or fittings. It enables installers to apply the recommended torque (up to approximately 16Nm) to ensure a secure and correctly aligned installation.

The composite construction is highly resistant to diesel, petrol, antifouling chemicals, and UV exposure, ensuring the tool remains reliable even in demanding onboard conditions.

Available in multiple sizes to suit different valve diameters, this spanner is an essential tool for boatbuilders, marine technicians, and DIY boat owners installing or servicing TruDesign plumbing systems.
