A John Guest brand push fit adapter to connect 8mm tubing to an NC keg ball lock disconnect. Just screw on the adapter (7/16" threads) to your ball lock disconnect. Then push in an 8mm polyethylene hose for a blow off tube or to connect your keg to the Fill Station bottle filler. Our 8x2mm polyethylene tubing gives you 4mm of ID and works perfectly with this fitting.
Made in the UK from certified food safe grey acetal copolymer. After cleaning or disinfecting your fittings according to the cleaning product manufacturer instructions, always rinse the fitting with clean water directly afterwards.
