GasBank EUROCONNECTOR M10 LPG filling adapter GB503 - for Spain and Portugal
- GasBank GB503 LPG filling adapter with EUROCONNECTOR coupling for filling points with M10 thread, e.g. DISH M10. Needed in: Spain and Portugal. Brass body, seal at the thread.
GasBank GB503 is an LPG filling adapter with a EUROCONNECTOR (EURO) coupling on the station side and an M10 thread on the vehicle side. Screw it into an M10 filling point - for example a GasBank DISH M10 remote filler in a motorhome or caravan - and fill autogas at stations whose nozzles use the EUROCONNECTOR (EURO) coupling. Mainly needed in: Spain and Portugal.

What it is for
- lets you fill LPG from a EUROCONNECTOR (EURO) nozzle into an M10 threaded filling point
- EUROCONNECTOR coupling - a European standard from the early 2000s; the nozzle clicks on in one movement and very little gas escapes when disconnecting
- fits filling points with an M10 (M10x1.5) thread, e.g. DISH M10 remote fillers
- one of the three M10 adapters needed to travel across Europe: ACME, BAYONET and EUROCONNECTOR

Where you need it
- Spain
- Portugal - alongside DISH
The DISH coupling, standard e.g. in Poland, France and Italy, needs no adapter if your filling point is a DISH type. The map shows which couplings you will find at European stations.
How to fill with the adapter
- switch off the engine and follow the station instructions
- remove the filler cap and screw the adapter into the M10 thread so that the seal sits evenly
- connect the station nozzle to the adapter and fill according to the station rules
- after filling, disconnect the nozzle, unscrew the adapter and refit the filler cap - a small amount of gas may escape when unscrewing
- keep the adapter in a pouch so that the thread and seal stay clean
Build
- body turned from copper alloy (brass)
- M10 thread with seal on the filling point side
- EUROCONNECTOR (EURO) coupling on the nozzle side
- compact size - fits a glovebox or an adapter pouch
Safety and regulations
- the adapter is intended for LPG (autogas)
- only fill tanks and cylinders designed for filling at a station, following their instructions
- rules on filling cylinders at stations differ between countries - check the rules of your destination before travelling
- before each use check that the seal is in place and undamaged
- do not fill if you smell gas or the connection leaks

Questions and answers
Does the adapter fit my filling point?

In which countries do I need it?
Mainly: Spain and Portugal. The map in the description shows couplings in other European countries.
Do I need all three adapters?
If you travel all over Europe - yes. A set of three M10 adapters (ACME, BAYONET, EUROCONNECTOR) is available in the shop.
Can I fill a cylinder at any station?
Not always. Rules differ between countries and stations - check the rules of your destination before travelling.
