OVERVIEW

Genuine ESAB Replacement O-Ring

The ESAB 0558101101 O-Ring is a critical sealing component designed for specific ESAB plasma cutting torches, including the popular PT-31 series. Manufactured to precise original equipment manufacturer (OEM) specifications, this O-ring ensures a tight, leak-proof seal necessary for the safe and efficient operation of your industrial machinery. Using genuine ESAB parts guarantees that the dimensional tolerances are exact, preventing gas leaks that can compromise cut quality or damage torch components.

Constructed from Buna-N (Nitrile Rubber), this O-ring offers excellent resistance to petroleum-based oils, water, and hydraulic fluids. The material is chosen for its durability and ability to maintain its mechanical properties across a standard operating temperature range. With a 70A Durometer hardness, it provides the perfect balance between flexibility for installation and rigidity for maintaining a seal under pressure.

Technical Specifications

This O-ring features an Inner Diameter (ID) of 0.301 inches and a Cross-Section (width) of 0.070 inches. These precise measurements are crucial for fitting into the designated grooves of ESAB torch heads or valve assemblies. Improperly sized generic O-rings can lead to failure, making this OEM part the reliable choice for maintenance and repair.

Regular inspection and replacement of O-rings are recommended during routine maintenance intervals. A worn or cracked O-ring can lead to pressure drops, gas wastage, or coolant leaks. Keep your equipment running at peak performance with this high-quality Buna-N replacement.
