Titan 0507273A Upper Packing Kit

Upper Packing Kit 0507273A for PowrLiner 2850 GB_D_F

The 0507273A upper packing kit is a complete seal replacement assembly for the fluid section on PowrLiner 2850 GB_D_F spray equipment. This kit contains all necessary components to rebuild the upper packing stack, including multiple styles of packings, o-rings, backup rings, and seals specifically engineered for this pump configuration. The upper packings create a dynamic seal around the piston rod, preventing fluid from bypassing during the pressure stroke and maintaining consistent output pressure. Over time, packings wear due to abrasion from paint particles, heat buildup, and normal mechanical cycling. Symptoms of worn packings include pressure fluctuations, material leaking past the piston, reduced spraying efficiency, and visible fluid seepage around the pump throat. This comprehensive kit includes every wear item needed for a complete upper end rebuild, eliminating the need to source individual components. Using genuine replacement packings ensures proper material compatibility and dimensional accuracy for reliable sealing. Regular rebuilding according to manufacturer recommendations extends pump life and maintains spray performance.
