The 341349 Oil Screw Plug is a genuine OEM fastener/sealing component designed for Elite 5500 and PowrLiner 4500/5500 airless sprayers. This threaded plug is typically installed in the pump housing or drive case to seal oil fill and drain ports, ensuring that lubricant remains contained within the system.
Proper lubrication is critical for the long life and reliable operation of airless sprayers. The oil screw plug maintains the integrity of the lubrication system by preventing leaks that could lead to low oil levels, inadequate lubrication, and eventual component failure. The plug is manufactured to exact thread specifications and includes a sealing surface that compresses against the housing to create a leak-tight seal.
Over time, oil plugs can become damaged from over-torquing, have their threads stripped, or develop corrosion that compromises sealing. A missing or damaged plug can allow oil to escape, leading to contamination of the work area, low oil levels, and potential damage to pumps, bearings, and drive components. Replacing a worn or damaged oil plug with this genuine part restores proper sealing and ensures adequate lubrication.

When replacing the oil plug, it's good practice to inspect these related components.
Check oil level and condition. Top up or change oil as needed when servicing the plug.
If the plug uses a separate sealing washer, inspect and replace it to ensure a leak-tight seal.
Inspect the port threads for damage that could affect plug sealing.
