Meter Star Propane fire Pit Whistle Free Gas Flex Line for Fire Pit and Fireplace - Stainless Steel (24" Long) 1/2" NPT Male x 1/2" NPT Female Corrugated Pipe

Good bargain for the money. Buy this because it’s a good deal. Don’t buy it because it says whistle free.Disappointed that I can’t turn my fire pit on high without a horrible whistle.Can’t fault the manufacturer because I don’t think you can get a gas line to not whistle.
