PartsMaster 3/8L Flat Faucet Washer - 5923

Restore a watertight plumbing seal with this PartsMaster 3/8L Flat Faucet Washer. This washer compresses at the mating plumbing connection to help prevent leakage when the correct size and profile are used.

5923 is a universal/spec-match product selected by its verified dimensions, ratings, connections, or application rather than by appearance alone.

Fitment / What To Verify: Match the part number, dimensions, ratings, connections, and intended application before ordering.

Is it time to replace?

• Common Symptoms: Drip or seepage at the joint, loose sealing, or a connection that cannot be tightened without leaking.
• Visible/Sensory Cues: Flattened, cracked, hardened, split, or distorted rubber and water tracks around the joint.

Pro Tip: Match washer size, thickness, profile, and mating surfaces; clean the joint before reassembly and do not overtighten plastic slip-joint parts.
