The Gaslow Spanish Clip-on Adapter 01-1671 is used to connect the butane hose with a 21.8LH fitting to Norwegian, Spanish, Portuguese and some southern Ireland gas cylinders. Normally connected to a bulkhead mounted 30mbar regulator via high pressure pigtails.
The Gaslow Spanish Clip-on Adaptor 01-1671 can also be used to connect to the Gaslow Local Cylinder connection hose. The adapter then converts the 21.8LH fitting on the 01-4500 hose to fit a gas cylinder connection in the corresponding countries.
Please note this adapter 01-1670 is not a regulator..
