Chapin 1266815 Garden Pump Sprayer Repair Seal Kit

Product Description

The CHAPIN 1266815 is a Pro-Series repair seal kit designed to restore proper pump function on poly garden sprayers. The kit contains the essential internal wear components that degrade over time with regular chemical and water use: seals, gaskets, a plunger cup, and a check valve. When a pump sprayer loses pressure, fails to prime, or leaks at the pump cylinder, these are the components that typically require replacement. This kit allows a technician or knowledgeable user to rebuild the pump assembly without replacing the entire sprayer unit.

This repair kit is intended for use with poly-body pump sprayers in garden, landscape, and light-duty agricultural applications. It is suited for situations where the pump cylinder has worn seals or a fatigued plunger cup causing loss of prime or pressure. Note that this kit is not rated as chemical safe, so it is best suited for water-based or mild solution applications rather than heavy-duty chemical service.

Key Features

Compatibility

Designed for use with CHAPIN poly pump sprayers. Refer to the sprayer model documentation or CHAPIN compatibility resources to confirm fitment before installation, as seal kit compatibility varies by sprayer series.

Installation Notes

Installation is typically performed by the sprayer operator or a maintenance technician familiar with pump sprayer disassembly. Before servicing, fully depressurize the tank by engaging the sprayer trigger until all pressure is released, then remove any remaining solution from the tank. Disassemble the pump cylinder according to the sprayer manufacturer instructions and replace all included components as a set rather than selectively, to ensure a proper seal throughout the pump assembly.
