The 138-153A Repacking Kit contains all the necessary seals, O-rings, packings, and gaskets required to rebuild the fluid section of compatible PowrLiner, PowrTwin, and PowrBeast sprayer models. This comprehensive kit restores pump performance, eliminates leaks, and ensures reliable operation.

Worn seals lead to internal bypass, pressure loss, and external leaks, reducing sprayer efficiency and causing material waste. This repacking kit includes every sealing component needed for a complete overhaul, allowing you to restore the pump to like-new condition.
Each component in this kit is manufactured to the exact specifications of the original parts, ensuring proper fit and reliable sealing. Regularly rebuilding the fluid section with this kit extends pump life, maintains consistent pressure, and ensures professional-quality results.
