KP2842-3 - Lincoln Electric Retaining Cap for LC25/LC30 Plasma Torches (KP2842-3)

Lincoln Electric KP2842-3 Retaining Cap Overview

The Lincoln Electric KP2842-3 Retaining Cap is an essential consumable designed specifically for the LC25 and LC30 plasma torches, commonly found on the Tomahawk 375 AIR and Tomahawk 30 AIR plasma cutting systems. This component plays a vital role in the plasma cutting process by securing the internal consumables—specifically the electrode and nozzle—within the torch head. A properly functioning retaining cap ensures that these critical parts remain perfectly aligned, which is necessary for maintaining a stable and focused plasma arc.

Manufactured to Lincoln Electric's exacting standards, this retaining cap is built to withstand the extreme temperatures and harsh conditions associated with plasma cutting. It is engineered to direct the flow of shielding gas effectively, protecting the nozzle from molten spatter and contributing to the cooling of the torch front end. Whether you are cutting mild steel, stainless steel, aluminum, brass, or copper, the KP2842-3 helps deliver consistent cut quality and extends the service life of your other consumables.

Over time, retaining caps can become damaged by heat, impact, or slag buildup, which can disrupt airflow and degrade cut performance. Replacing a worn retaining cap with this genuine Lincoln Electric part restores your torch to its original factory specifications. It is designed for external air applications and ensures a tight seal to prevent gas leaks that could compromise the cutting arc. This package contains one (1) retaining cap, making it a convenient replacement part to keep on hand for maintenance and repair tasks.

For operators in construction, automotive repair, and general fabrication, using genuine Lincoln Electric consumables like the KP2842-3 is the best way to ensure safety and reliability. It guarantees compatibility with your LC25 or LC30 torch, eliminating the guesswork and potential risks associated with aftermarket parts. Keep your Tomahawk plasma cutter running at peak efficiency with this durable and precise retaining cap.
