Itβs pretty important to stock your tool kit with all the little bits and pieces you might need for future repairs and installations. Gas orifices might not look like much, but these little guys act like the transfer stations that connect and regulate the gas-infused super highways that keep your equipment working properly. Without the right-sized orifices in place you can quickly clog up a gas line or put a piece of equipment out of commission, which is why having a handful of different orifice designs and styles at the ready gives you the upper hand as either a technician or DIY enthusiast.
