Graco 15C875 Nut Packing – Comprehensive Overview

Product Description

The Graco 15C875 Nut Packing is a critical sealing component designed for use in high‑pressure paint sprayer systems. This packing nut holds the packing or seal assembly firmly in place, preventing fluid leaks and maintaining consistent pressure performance. Built to OEM specifications, the part ensures the sealing integrity of the pump or fluid‑end section under intense operational conditions.

Key Features & Benefits

• Precisely machined to OEM tolerances for secure, leak‑free fitment
• Designed to clamp packing or sealing elements in high‑pressure assemblies
• High‑quality material construction ensures durability under repeated cycles and high pressures
• Maintains system reliability by preventing fluid or air ingress around critical pump components

Technical Specifications

Applications & Practical Use

• Used in pumps or fluid‑end sections of airless paint sprayers where packing must be retained securely
• Helps maintain sealing integrity under high pressure and repetitive cycling
• Prevents leakage around packing nuts which can lead to performance loss or damage
• Essential for maintenance and rebuilds of sprayer systems to restore OEM sealing capability

Installation & Maintenance Tips

• Ensure surfaces and threads are clean before installation to prevent misalignment or leaks
• Use the correct torque specification as recommended by the manufacturer to avoid over‑tightening or under‑clamping
• Inspect the nut periodically for signs of thread wear, corrosion, or leakage and replace if necessary
• During maintenance, always replace dependent packing elements when installing the packing nut to ensure full performance restoration
