OVERVIEW

Maintain Peak Performance with Genuine ESAB Parts

The ESAB O-Ring .489 ID X .07 (Part Number 0558004749) is a critical maintenance component designed for specific ESAB plasma cutting torches. In the high-stakes environment of industrial cutting, even the smallest seal plays a pivotal role in the overall efficiency and safety of your equipment. This O-ring is engineered to precise factory specifications, featuring an inner diameter of 0.489 inches and a cross-section thickness of 0.070 inches, ensuring a flawless fit within the torch assembly.

O-rings in plasma torches are responsible for segregating gases, sealing coolant channels, and maintaining the internal pressure required for a stable plasma arc. Over time, heat cycling, exposure to plasma gases, and general wear can degrade these seals, leading to potential leaks. A compromised O-ring can result in poor cut quality, increased consumable consumption, or even damage to the torch head. By choosing this genuine ESAB replacement, you are investing in the longevity of your machine.

Installation is straightforward during routine maintenance intervals. We recommend inspecting all O-rings whenever you change consumables to catch signs of cracking, flattening, or brittleness early. Using genuine OEM parts like the 0558004749 guarantees that the material composition is compatible with the temperatures and pressures unique to ESAB equipment, providing peace of mind and consistent operation.

Yes, this is a genuine ESAB OEM replacement part, number 0558004749.

A worn O-ring can cause gas or coolant leaks, leading to poor cut quality, arc instability, and potential damage to the torch head.

It is designed for specific ESAB plasma torches, commonly found in the PT series (e.g., PT-37). Please check your equipment manual for the specific part number 0558004749.

It is generally recommended to apply a very light film of silicone lubricant compatible with your torch's O-rings to prevent tearing during installation and ensure a good seal.

You should visually inspect O-rings every time you change consumables. Look for cracks, flat spots, or cuts and replace immediately if found.

It is not recommended. OEM O-rings are made of specific materials designed to withstand the heat and chemicals present in plasma cutting. Generic rings may fail prematurely.
