0152475035 - ESAB Grease Nipple for PKB 250/400 Wire Feeder Motor

Keep Your Wire Feeder Running Smoothly

As a welder, you know that consistent wire feeding is the backbone of a good weld. If your wire feeder motor starts to grind, hesitate, or overheat, your arc stability suffers, and so does your weld quality. The ESAB Grease Nipple for PKB 250/400 (0152475035) is the small part that prevents these big headaches. Designed for the motor assembly of your ESAB machine, this fitting allows you to easily apply grease to the internal gears and bearings, keeping the heart of your wire feeder running like new. Over time, original grease nipples can become clogged with shop grime, painted over, or snapped off during transport, making it impossible to service the machine properly.

Replacing a damaged or missing grease nipple is one of the easiest and most effective repairs you can perform. This genuine ESAB part ensures a perfect fit into the motor housing of your PKB 250 or PKB 400 unit. Once installed, it creates a secure seal that keeps dirt and metal dust out while allowing your grease gun to snap on securely. Proper lubrication reduces the strain on the drive motor, which translates to smoother wire delivery and less spatter caused by feeding interruptions. It is a simple fix that protects your investment in professional-grade equipment.

Don't let a ten-cent maintenance issue turn into a thousand-dollar repair. If you are noticing noise from your feeder or if it has been a while since the machine was serviced, check your grease fittings. If they are damaged or blocked, swap them out with this authentic ESAB replacement. It is designed to withstand the rigors of the welding shop, providing a reliable access point for maintenance for years to come. Keep your gear in top shape and your welds consistent with the right parts for your ESAB machine.
