Frequently Asked Questions
Not all variants. It fits models that use the Q-Pump style lower. Always verify your pump lower and part number in the manual before purchase.
Loss of pressure, pulsation, material leaking past packings, or frequent re-priming are common signs that packings are worn and need replacement.
Basic hand tools typically suffice. Follow the service manual for safe disassembly, packing order, and torque values. A soft-jaw vise and assembly lube are helpful.
Leather and polyethylene (PE) elements are commonly used in this kit to balance sealing, lubrication retention, and durability for high-pressure use.
After reassembly, prime with compatible solvent or material at low pressure, check for leaks, then gradually ramp to operating pressure while monitoring performance.
