Discontinued beer faucet parts can be tough to find. Keep your favorite 500 series Perlick faucet working to perfection with this genuine replacement O-ring.


    Looking to repair or rebuild your trusty 500 series Perlick faucet? One of the first parts you’ll want to replace is the shaft O-ring, and these discontinued beer faucet parts can be difficult to find.

    The O-ring is positioned at the back of your faucet and creates a tight seal. Over time, the rubber material can break down, resulting in leaks and difficulty operating your beer faucet. Instead of replacing the entire faucet tap head, you can save money by installing a new O-ring.

    Made of durable rubber, this is a genuine Perlick replacement part, meaning you can count on a perfect fit and optimal quality. If it’s not a true Perlick part, then it doesn’t belong in your faucet.

    This replacement O-ring is made specifically fo Perlick 525 and 575 series faucets. If you have a different faucet, you’ll want to find the part made for your model. Replacing your O-ring can be done in a few easy steps. Just disconnect the faucet tap head from your draft tower, remove the outer ring, remove the defective O-ring, replace with this new O-ring, re-connect the outer ring, and re-attach the faucet head to the draft tap tower.
