Frequently Asked Questions

Match the gun model, not just the sprayer. This kit fits Silver Plus and Flex Plus airless guns (except model 235462), regardless of which sprayer the gun is connected to.

Dripping from the tip when released, trigger not returning crisply, internal leaks, or inconsistent spray patterns typically indicate worn needle/seat or packings that this kit addresses.

No. Tips and guards are sold separately. This repair kit focuses on internal shut-off and sealing parts (needle, seat, packings, and related small hardware).

235474 is the current kit that replaces 235187. If your documentation references 235187, you can use 235474 as the updated equivalent.

Always relieve pressure, wear eye/hand protection, and follow the gun’s service manual. After assembly, test at low pressure with solvent or water to confirm proper shut-off before spraying coatings.
