Here at Barbecues Galore we offer a lot of gas services - gas line installations, fireplace installations, hook ups, etc - and therefore we have a lot of gas fittings. We have put the common ones on our website that you - the homeowner - should be okay to use on your own. If there is a particular fitting you are after, then get in touch with us and we will hook you up. If we can.
