The Titan 0533525 Pipe Plug is an OEM threaded plug designed for the AirCoat 423 spray system. It is used to seal unused female ports on manifolds, pump housings, or fluid passages, preventing leakage, contamination, and pressure loss.
Pipe plugs can become damaged due to overtightening, corrosion, or thread galling. A missing or damaged plug can cause fluid leaks, air ingestion, or debris entry. Replacing with an OEM pipe plug ensures correct thread fit, proper sealing, and reliable operation.
