| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan/SprayTECH 51357 split lock washer, 5/16". Listed in the official PowrCoat 630 parts diagram as "Rondelle de blocage" (lock washer). Genuine Titan fastening hardware for reliable vibration resistance. |
| Function | Installed under the head of a bolt or under a nut to provide spring tension that resists loosening caused by vibration, thermal cycling, or dynamic loads. The split action creates tension that resists rotation, maintaining clamping force on critical fasteners. Prevents component misalignment and mechanical failure due to loose hardware. |
| Compatible Models | Titan PowrCoat 630, AirCoat 423, AirCoat 620. SprayTECH EP2300, EP2300SE, EP2400, EP2510, EPX2305, EPX2455, EPX2555. Wagner ST595. Verify fitment against your specific model parts diagram before ordering. |
| Replacement Indicators | Fasteners that frequently loosen. Visible flattening of the washer (loss of spring gap). Corrosion, cracks, or breakage. During routine disassembly of bolted joints, always replace lock washers as they lose spring tension after being compressed. |
| Service Guidance | Lock washers can lose their spring tension after being compressed. Always install a new washer when servicing to ensure proper locking action. Inspect washers for signs of fatigue, cracking, or loss of spring tension. Do not reuse old lock washers. |
| Related Parts Serviced Together | Bolts, nuts, flat washers, and mounting hardware. Inspect these during lock washer replacement to ensure complete and secure assembly. |
| Commercial Benefits | Restores proper clamping force, prevents fastener loosening, reduces risk of mechanical failure, and ensures safe, reliable operation of the sprayer. |
The 51357 Split Lock Washer is a practical replacement for contractors and service technicians maintaining compatible Titan and SprayTECH sprayers. This small fastening component plays a critical role in preventing fastener loosening due to vibration, which can lead to component misalignment, fluid leaks, or mechanical failure. If a lock washer is flattened, cracked, corroded, or missing, replace it promptly. Always install new lock washers during reassembly of bolted joints, as used washers lose their spring tension and locking effectiveness. Using the correct OEM washer ensures proper fit and reliable vibration resistance for safe, consistent sprayer operation.
