Lightweight steel LPG cylinder with an 80% overfill limit valve (OPD - Overfill Protection Device) and a separate DUO inlet and outlet.

• DUO valve system: Features separate inlet and outlet valves, allowing you to connect an external body / chassis fill point without disconnecting your gas regulator.
• Integrated 80% OPD Safety Valve: Automatic Overfill Protection Device shuts off filling at 80% capacity for effortless, legal refilling across the UK & Europe.
• Ultra-lightweight DUPLEX steel: Crafted from high-strength dual-phase DUPLEX steel, weighing only approx. 5 kg empty.
• C5-M marine-grade coating: C5-M anti-corrosion finish protects against harsh road conditions, salt air, and rust.
• Built-in Pressure Relief Valve (PRV): Safety relief valve prevents dangerous internal overpressurisation (opens above 27–30 bar).
• Compact SLIM footprint: Engineered to fit tight gas lockers in campervans, motorhomes, caravans, and gas BBQ cabinets.

The DUO version features separate inlet and outlet connections, making it the ideal refillable LPG solution for permanent, external fill point installations.

The DUO valve advantage - seamless external refilling

GasBank DUO system allows you to permanently fit an external filling point onto your vehicle’s sidewall or chassis. You never disconnect your regulator. Fill up at any LPG/autogas station without unhooking your gas appliances or removing the cylinder from the locker. Non-return inlet valve - features a dedicated check valve on the inlet side for safe, leak-free remote refilling.

Maximum safety with automatic 80% OPD & PRV

80% OPD (Overfill Protection Device) automatically stops the filling process when the cylinder reaches 80% capacity (~10.1 litres of LPG), preventing overfilling risks. Pressure Relief Valve (PRV) is a built-in safety valve that releases pressure if internal cylinder conditions exceed 30 bar.

DUPLEX lightweight steel & C5-M coating

Constructed from advanced DUPLEX low-carbon steel, the SLIM LS DUO offers maximum wall strength at a tare weight of just ~5 kg. Protected by a premium C5-M marine-grade coating, this cylinder resists moisture, salt air, and road spray, guaranteeing years of reliable outdoor service.
