Inquiry (采购产品): finned tubing I am interested in stamped fin tubing with fin size approx. 2 x 2 inches. Length 18 inches for assembly into heat exchanger modules. Will be used in water to air application. Do you also sell 180 deg. return bend fittings for soldering on ends of tubes and other hardware that might be needed to form a complete heat exchanger? **** Hidden Message ***** Allen Zumbrunnen 84115-1523 Company: none E-mail: allenzum@burgoyne.com **** Hidden Message ***** allenzum@burgoyne.com
