Product Description
The DEWALT 5140187-19 is a piston and cylinder kit designed as a replacement assembly for DEWALT pneumatic or compressor-driven power tools. This kit services the core compression components responsible for building and maintaining air pressure within the pump assembly. Worn or damaged pistons and cylinders cause loss of pressure, excessive noise, and reduced tool performance. Installing a genuine OEM-specification replacement restores the unit to factory operating condition. This type of repair is typically performed by power tool technicians or experienced service personnel familiar with pneumatic tool and air compressor disassembly.
The DEWALT 5140187-19 piston and cylinder kit is suited for use in compressor or pneumatic tool service applications where the original piston or cylinder bore has worn beyond acceptable limits. It is intended for use by service technicians performing pump-end rebuilds or component-level repairs on compatible DEWALT equipment. Specific compatible model numbers were not provided in the available product data.
