This stainless gas side fitting screws onto the gas in fitting of any Sanke coupler, and converts it to accept gas ball lock fittings. Makes it really easy to switch between a commercial keg and a ball lock home brewing keg. This is just the horizontal gas side, you will need to order P62 (beer side which goes on top) in order to make both sides of your Sankey coupler ball lock.
Includes inner sealing washer. To prevent leaks, tighten by hand firmly, and then use a wrench to tighten 1/4 of a turn. Overtightening will distort the inner sealing washer, causing leaks.
