Dear HBF members - just a word of caution - the use of high pressure gas can be dangerous if fixtures, fittings, receptacles and any associated equipment are modified, adapted or otherwise 'tinkered with', or if all instructions are not adhered to. If in doubt, speak to a reputable supplier for their advice.
So please be careful, and HBF cannot be held responsible for any advice, correct or otherwise, that might be given on the forum.
