274841 - Miller Rectangular Tube Plug Insert

Genuine Miller Replacement End Cap for Equipment Frames

Maintain the professional appearance and safety of your Miller welding equipment with the Miller 274841 End Cap, Tube Insert Rectangular Ribbed. This component is a genuine OEM replacement part designed specifically to fit the rectangular tubing found on various Miller welding carts, machine frames, and running gear. Over time, the original plastic inserts on industrial equipment can become damaged, loose, or lost due to the rigors of the shop environment. Replacing them is a small but essential maintenance step that preserves the integrity of your machine's chassis.

The 274841 insert features a specialized ribbed design on the shank. These flexible ribs compress upon insertion, creating a tight friction fit against the inner walls of the metal tubing. This ensures that the cap stays securely in place even when the equipment is subjected to vibration during transport or operation. The rectangular head sits flush against the end of the tube, providing a clean, finished look that hides the raw cut edge of the steel.

Safety and Protection

Beyond aesthetics, tube inserts play a critical role in shop safety. Open metal tubing often has sharp, burred edges that can snag clothing, cut skin, or damage welding cables dragged across them. By capping these ends with a smooth, durable polymer insert, you eliminate these hazards. Furthermore, the cap acts as a barrier against the ingress of workshop debris. Grinding dust, metal shavings, and moisture are prevented from accumulating inside the frame, which helps reduce internal corrosion and extends the lifespan of your equipment structure.

Trust in genuine Miller parts to ensure the correct dimensions and material quality. Generic universal plugs may not match the specific wall thickness or corner radius of Miller tubing, leading to loose fits or gaps. The Miller 274841 is engineered for a perfect snap-fit installation, requiring no adhesive or special tools.
