Item #: 4019
Is your keg coupler leaking? The rubber check valve is a vitally important piece that often needs replacing if that is the case. This rubber check valve is for a US Sankey keg coupler.
A check valve seems like such a minor keg coupler part that sometimes it is discarded when people think it is just part of the product's packaging. However, it is a key piece of equipment that prevents beer from the line entering the coupler and causing a leak.
It is important to replace this keg tap part if it becomes lost, cracked, or worn out. Due to its size, this may happen more frequently than other components of your draft system, so it's never a bad idea to have a few extras on hand.
