This Truma gas solenoid 8mm and switch is for motorhome and leisure use, working on low pressure (after the regulator) gas supply pipeline.
It will isolate the gas supply by switching the switch from inside the vehicle.
Based on a 12v system this unique solenoid only uses 40ma current draw when in operation. This makes it very good for vans on long stay sites on leisure battery only.
The solenoid simply fixes into the pipeline by the use of compression fittings.
Please note: the switch and surround are in black.
