The black rubber O-Ring creates a liquid tight seal between the faucet body and the lever assembly and is seated in the bottom most groove inside the body of Perlick Faucet’s.
If the Perlick Faucet leaks from the nozzle following closure of the handle lever, the o-ring may be worn out and in need of replacement.
To locate the o-ring, remove the handle jacket, compression bonnet and lever assembly from the top of the faucet body. The o-ring will be visible above the main cavity of the faucet.
The o-ring is easily extracted from the groove while the faucet is still attached to the faucet shank. To remove the o-ring, sanitize a pair of slender needle nose pliers and a jeweler’s screwdriver. Use the tools to dislodge, grasp and remove the o-ring from the groove.
To install a new, sanitized o-ring, insert the o-ring into the opening created by the removal of the lever assembly. Use the jeweler’s screwdriver to gently situate the o-ring into the lower most groove situated above the faucet cavity. Once the o-ring has been accurately placed in the groove, spray sanitizer inside the cavity and re-install the sanitized lever assembly, compression bonnet and handle jacket.
