Harrison from Valley Center writes

Will the Chapin Replacement Pump Piston Collar for Backpack Sprayers (6-8134) fit a Stanley 61804 backpack sprayer?

size of the little piston is 1.65 dia? That is the size of the piston where the valve fits onto it.

Answer:

We only recommend using Chapin parts in Chapin sprayers. Chapin does make many Stanely brand sprayers, and the piston collar #6-8134 should fit the Stanley model 61804 sprayer. If you are not sure of your exact sprayer model, then we recommend calling Chapin directly at 800-950-4458.
