1/4-18 NPT Female Aluminum Weld Bung
These weld on female bungs are machined from 6061-T6 aluminum, and tapped for 1/4-18 Npt male fittings. These bungs have a 19mm(3/4") OD and a length of 32mm (1 1/4"). The extra length reduces deformation of the threads when welding, and allows these bungs to be coped up to 45 degrees. These can be used for installing hose barb or AN style fittings.
