The valve shaft seat washer is responsible for stopping the flow of beer on a standard style beer faucet.
This washer is located inside the rear of your faucet.
If the washer is worn, cracked or damaged you may have beer leaking from your taps. This simple washer fixes all that!
We recommend using a faucet wrench (sold separately) to tighten and loosen your coupling nut to avoid damaging your equipment or tools.
