The GRACO 181895 is a packing nut, a critical component used in GRACO pump assemblies to secure and compress packing material around the displacement rod, ensuring a reliable seal and preventing fluid leakage. The main material is not explicitly specified in available listings, but packing nuts are typically constructed from durable metals such as brass or steel for longevity and resistance to wear. Its intended use is to maintain the integrity of the pump’s sealing system within GRACO equipment.

Key Features:

• Packing Nut
• Designed for secure compression of packing material
• Promotes reliable sealing and reduced leakage
• Supports ease of maintenance and replacement

Applications:
Used in GRACO pump assemblies to maintain seal integrity and prevent fluid leakage during operation. Suitable for industrial, mining, and agricultural applications where reliable pump performance is essential.

Installation Notes:

• Using a genuine GRACO packing nut ensures proper fit, optimal sealing, and reliable pump performance. Non-genuine parts may compromise safety and efficiency.
• Ensure the packing nut is tightened to the manufacturer’s recommended torque to avoid over-compression or under-compression of the packing material.
• Regularly inspect the packing nut and packing material for wear and replace as needed to maintain seal integrity.
• Keep the packing nut/wet-cup one-half full with GRACO Throat Seal Liquid (TSL) to help prevent the pumped fluid from drying on the displacement rod.
