     Labelled parts of Campingaz regulator

Control knob

Campingaz control knob close-up The control knob operates a ball valve inside the regulator which rotates to turn the gas supply on and off as required.

You turn the knob anti-clockwise to switch on the gas, and clockwise to switch it off.

Regulator outlet pressure

Special 30mbar regulators are now used on newer caravans for both butane and propane, where the appliances will be designed to work at this pressure. Most portable appliances should also work satisfactorily at this pressure, but it’s always best to check the manufacturer’s specifications first.

Regulator outlet nozzle

Close-up of Campingaz nozzle The outlet is the pipe through which the gas leaves the regulator to enter the appliance, and includes ridges to help keep the hose clips in place.

Different makes of Campingaz style regulators are available but the design is the same, with the nozzle always 8mm in diameter.

Regulator seal

Close-up of Campingaz rubber seal The seal, also called a sealing washer, is there to make sure the regulator fits tightly on the cylinder to minimise gas leaks.

It’s usually made of oil-resistant synthetic rubber, although pure rubber is sometimes used. Butane gas erodes rubber, so check the seal regularly for signs of wear and replace it if there are any cracks.

Regulator inlet and screw thread

Close-up of Campingaz inlet and screw thread underneath regulator The inlet pushes down on a ball valve inside the cylinder which allows the gas to be drawn up into the regulator. The cylinder is self-sealing, which means that when you remove the regulator the ball valve will automatically shut off the gas.

The screw connector has a right-hand thread, so you turn the regulator clockwise when attaching it.
