This stainless beer side fitting screws onto the top beer out fitting of any Sankey coupler, and converts it to accept beer (liquid) ball lock fittings. Makes it really easy to switch between a commercial keg and a ball lock home brewing keg. This is just the top beer side, you will need to order P61 (gas side) in order to make both sides of your Sankey coupler ball lock.
Includes inner sealing washer. For best results, hand tighten firmly, and then tighten a quarter turn with a wrench (overtightening will distort the inner sealing washer).
