The GRACO 17T042 Kit is a replacement lower hard seat assembly for the MD2 valve, designed for use with GRACO MD2 dispensing valves. It is constructed with hard seat materials, typically carbide, for enhanced durability and resistance to abrasive materials. This kit is intended to maintain or restore the sealing and dispensing performance of MD2 valves in demanding industrial applications.

Key Features:

• Lower hard seat kit for MD2 valve
• MD2 (specific to lower hard seat configuration)
• Hard seat (carbide or similar hardened material)
• Compatible with MD2 valves rated up to 3000 psi (20.7 MPa, 207 bar) maximum working pressure
• Designed for use with GRACO MD2 valves, especially those requiring hard seat assemblies for abrasive materials
• Hard seat construction for durability and resistance to abrasive materials
• Designed for reliable sealing and long service life
• Ease of maintenance and replacement as part of a kit

Applications:
Used in industrial dispensing systems for sealants, adhesives, and other materials where abrasive resistance and reliable sealing are required. Suitable for applications in manufacturing, construction, and maintenance environments where MD2 valves are utilized.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the MD2 valve system.
• Follow the manufacturer’s instructions for disassembly and reassembly of the MD2 valve
• Ensure all components are clean and free of debris before installation
• Lubricate o-rings and seals as recommended in the manual
• Tighten all fasteners to the specified torque values
• Inspect for leaks and proper operation after installation
• Regularly inspect the hard seat and needle for wear or damage
• Replace the lower hard seat kit as part of routine maintenance or when performance issues arise
• Use only recommended lubricants and replacement parts
