Part 4924913 1/2" NPT Halloe Hex Plug Component Usage

The 1/2" NPT Halloe Hex Plug (part 4924913) is a specialized component utilized in various engine systems to ensure efficient operation and maintenance. Its role is significant in the following components:

208-230V AC Prelub Pump

In the 208-230V AC prelub pump system, the 1/2" NPT Halloe Hex Plug is often used to seal off unused ports or passages. This ensures that the lubricant is directed correctly through the system, preventing leaks and maintaining pressure integrity. The plug’s hexagonal shape allows for easy installation and removal using a standard hex key, facilitating routine maintenance and inspections.

Engine Lubrication Primer

Within the engine lubrication primer, the 1/2" NPT Halloe Hex Plug serves to block off sections of the priming circuit that are not in use. This helps in maintaining the primer’s efficiency by ensuring that the lubricant flows only through the necessary pathways. The plug’s robust design ensures that it can withstand the pressures and temperatures encountered during the priming process.

Engine Lubricating Primer

Similar to its function in the engine lubrication primer, in the engine lubricating primer, the 1/2" NPT Halloe Hex Plug is employed to seal off non-operational passages. This is particularly important during the initial start-up phase of an engine, where proper lubrication is essential to prevent wear and damage. The plug ensures that the lubricant is effectively distributed throughout the engine components that require it.

Primer

In a general primer system, the 1/2" NPT Halloe Hex Plug is used to manage the flow of lubricant by sealing off unnecessary pathways.
