Titan 773-031 Stem Gland

Stem gland 773-031 for HVLP spray guns

The 773-031 stem gland is a precision sealing component used in the fluid section of compatible HVLP spray guns. It is designed for use with HVLP Airspray C100 Gun; HVLP Airspray ProFinish Gun; and HVLP Airspray Profinish TS40 TS 50 models. The stem gland fits around the needle or valve stem, providing a fluid-tight seal that prevents coating material from leaking back into the gun body or air passages. It also guides the stem smoothly during trigger operation, ensuring consistent fluid flow control. The gland is typically made from a wear-resistant material such as PTFE or a specialized polymer that can withstand exposure to solvents and paints. Over time, the stem gland can wear, harden, or become damaged due to friction, chemical attack, or contamination. A worn gland may allow fluid to leak into the gun, causing drips, poor atomization, and difficult cleanup. Symptoms of a faulty stem gland include visible fluid leakage around the trigger area, inconsistent spray pattern, or material buildup inside the gun. Replacing a worn gland with this genuine part restores a positive seal and smooth needle operation. This is a common repair during routine gun maintenance. Using the correct replacement ensures the gun performs reliably and prevents material waste.
