Inquiry (采购产品): plug orifices, cap orifices wanted to know if you made cap orifices for black pipe. I want to make burners ot of black pipe to fire pig roasters. I have seen units that have cast iron slotted caps to create a venturi draft with propane line running throug the center of it. If you carry these I would be interested in them thank you **** Hidden Message ***** bill janzer 25427 Company: md pig roasters E-mail: mdblz123@yahoo.com **** Hidden Message ***** mdblz123@yahoo.com
