Code: 129089 This ball valve is sold as a complete assembly so all you have to do is drill your 20mm hole in your keg, pot or vessel wall and you can fit this ball valve. This is a full port ball valve with a 14mm bore which allows maximum flow rate through the ball valve. The valve comes with Teflon tape already on the nipple, a silicon o-ring which is seated in the ½” BSP nut. The seat in the nut prevents the o-ring from rolling out of place when tightening. The 1/2” BSP Male x 13mm Barb (part no. 5700 shown in the picture to the left) can be fitted to the ball valve so you can attach any 11-14mm ID type hose (such as our silicon hose part no. 5496) On the inside of the vessel the ½” BSP nipple usually protrudes approximately 16mm meaning you can attach an elbow to the inside of the vessel so it draws from the bottom (shown in the picture to the left) Note: does not include the elbow or 13mm barb
