GasBank LS DUO 11 kg is a refillable steel LPG cylinder made of high-strength light steel. It holds 11 kg of propane with a water capacity of 26.2 l. It has a DUO valve with separate inlet and G.12 (KLF) outlet and 80% OPD. The cylinder is certified in the same way as standard steel cylinders, so in a motorhome, caravan or at the barbecue you use it just like an exchange bottle.

Light steel 11 kg cylinder
- water capacity: 26.2 l
- filling to 80%: approx. 21 l LPG, i.e. 11 kg of propane
- tare (with valve): approx. 6.95 kg
- diameter: 300 mm, footring 303 mm
- height: approx. 584 mm (+/- 5 mm)
A 300 mm diameter is the standard for 11 kg cylinders, so it fits typical gas lockers.

DUO valve - separate inlet and outlet
- filling inlet with 3/4" UNF (JIC) thread and non-return valve
- G.12 (KLF) gas outlet, thread W21.8 x 1/14 left-hand, with rubber seal
- the filling kit can stay connected, no need to unscrew the regulator
Connect the inlet by hose to an external LPG filling point and the outlet to the regulator of your gas system - just as with a standard cylinder.

80% OPD and safety valve
- the OPD system stops filling automatically at 80% of capacity
- the safety valve (PRV) opens at 27 bar
- test pressure: 30 bar, minimum burst pressure: 67.5 bar

Certification - in a motorhome like a standard bottle
- designed and certified to EN 14140:2014 + AC:2015 for welded steel LPG cylinders
- Directive 2010/35/EU (TPED) - Pi mark and notified body number TÜV 0035 on the footring
- approved for transport to ADR/RID 2025
The GasBank LS DUO is made and certified to the same standard and directive as standard steel exchange cylinders. According to its certification, you can therefore use it in a motorhome just like a standard exchange cylinder: place it in the gas locker, secure it with a strap and connect it to the regulator with the same hose. On the outlet side, the connection is no different from a standard cylinder.

Questions and answers
Can I use this cylinder in a motorhome?
Yes. The cylinder is certified to EN 14140 and the TPED directive, like standard steel exchange cylinders, so you use it in a motorhome in the same way: in the gas locker, with the same regulator and hose.
How full does the cylinder get?
The OPD system stops filling at 80% of capacity, i.e. at approx. 21 l LPG out of a 26.2 l water capacity.
Do I have to disconnect the regulator when filling?
No. The DUO valve has a separate inlet to which the hose from the external filling point stays connected.
Which regulator fits the outlet?
Any regulator with a G.12 (KLF) connection, the same as for standard 11 kg cylinders in Poland and Germany.
