Frequently Asked Questions
Check your sprayer’s parts manual exploded view and match the pump family and rod size (¼"). If 165279 appears in the pump diagram bill of materials, it’s the correct rear packing housing.
Yes—rear housing removal is a good time to install a fresh packing set. Reusing worn packings can cause immediate leaks and premature failure.
Persistent leakage at the rear of the pump, difficulty holding pressure, or visible scoring in the housing bore suggest replacement. Confirm rod straightness and packing condition as well.
