ABSTRACT:
A flow control device for filtering and restricting the flow of gas from a gas supply system. Gases stored under pressure in containers or tanks are widely employed in many industries. Such gases are often toxic or explosive, and systems employing such gases must be secure against leaks, clogging and the like. The connector fitting structure includes a flow restrictor plug device and a filter. The connector fitting includes screw threads and may be easily screwed into an end fitting of a gas container and which requires no additional joints to be added to the gas system wherein a minimum volume of gas is trapped external to the gas container in the event of a clogging condition.
