Titan 0509586 Upper Seal

Upper seal 0509586 for SprayTech LCX 750 and GPX 750

The 0509586 upper seal is a precision sealing component installed in the pump assembly of compatible SprayTech sprayers. It is specifically designed for use with SprayTech LCX 750 and SprayTech GPX 750 models. This seal fits around the piston rod, creating a fluid-tight barrier that prevents coating material from leaking out of the top of the pump during operation. It also helps exclude contaminants from entering the pump chamber. The seal is typically made from a wear-resistant material such as polyurethane or PTFE, formulated to withstand the abrasive and chemical nature of paints and solvents. Over time, upper seals can wear, harden, or become damaged due to friction, chemical attack, or contamination. A worn seal will allow fluid to leak past, resulting in visible drips, loss of pressure, and a mess around the pump area. Symptoms of a failing upper seal include fluid leaking from the top of the pump, reduced spray pressure, and material buildup on the piston rod. Replacing a worn upper seal with this genuine part restores a positive seal, maintaining pump efficiency and preventing waste. This seal is typically replaced as part of a routine pump rebuild or when leaks are detected. Using the correct replacement ensures proper fit and long-lasting performance.
