Part number 872-005 is a Flat Nylon Washer specifically engineered for use across a range of professional sprayer systems including Hydra M and Hydra Pro 2000_4000 series, Hydra M and Hydra Pro Super, and 0528925N_2000_4000 models. These industrial-grade units are designed for demanding coating applications requiring reliable, high-pressure fluid delivery up to 4000 PSI. This nylon washer provides several critical functions in equipment assembly: it distributes fastener load to prevent damage to painted or soft surfaces, provides electrical insulation between dissimilar metals to prevent galvanic corrosion, and acts as a vibration-damping cushion between components.
Manufactured from high-quality nylon, this washer offers excellent chemical resistance to paints, solvents, and cleaning agents commonly encountered in professional finishing environments. The material is non-conductive, non-magnetic, and will not rust or corrode. Nylon's natural lubricity reduces friction during fastener installation and prevents galling. The precise inner and outer diameter dimensions ensure proper fit with the specified fasteners, while the flat, parallel surfaces provide even load distribution across the mating component.
Nylon washers are subjected to continuous compression, vibration, and chemical exposure. Failure modes include deformation from over-torquing, chemical attack causing softening or embrittlement, and wear from repeated use. A damaged, deformed, or missing nylon washer can lead to inadequate clamping force, loosening of critical components, damage to painted surfaces, and galvanic corrosion between dissimilar metals. Replacement with genuine 872-005 flat nylon washer ensures proper load distribution, surface protection, and long-term reliability of Hydra M, Hydra Pro, and related spray systems.
| Load Distribution | Spreads clamping force to prevent surface damage |
|---|---|
| Electrical Insulation | Prevents galvanic corrosion between dissimilar metals |
| Vibration Damping | Cushions components and reduces noise |
| Deformation | Washer is crushed, warped, or distorted |
|---|---|
| Chemical Attack | Softening, cracking, or discoloration from solvents |
| Compression Set | Washer no longer provides adequate thickness |
| Component Service | Replace whenever associated components are disassembled |
Part number 872-005 is specifically designed for use across a range of professional sprayer systems including Hydra M and Hydra Pro 2000_4000 series, Hydra M and Hydra Pro Super, and 0528925N_2000_4000 models. These industrial-grade units deliver up to 4000 PSI operating pressure for commercial and industrial coating applications. The flat nylon washer is a universal component engineered for the insulation, protection, and load distribution requirements across these diverse professional platforms.
