2217 - ESAB R64 Regulator Burst Disc (Pack of 5)

Critical Safety Component for Gas Regulation

The ESAB Safety Valve Disc R64 is a vital maintenance component designed for the safe operation of industrial gas regulators. In the field of oxy-fuel welding and cutting, as well as shielding gas regulation, the integrity of pressure relief devices is paramount. This safety valve disc, often referred to as a burst disc or rupture disc, serves as the last line of defense against over-pressurization events. When the internal pressure of a regulator exceeds its design limit due to seat failure or improper usage, this precision-engineered disc is calibrated to rupture, venting the excess gas safely to the atmosphere rather than allowing the regulator body to explode or the low-pressure gauge to fail catastrophically.

OEM Quality and Compliance

Using genuine ESAB parts like the R64 disc is essential for maintaining the safety certification and operational parameters of your equipment. Aftermarket or incorrect discs may not rupture at the correct pressure, leading to dangerous working conditions. The R64 is manufactured to tight tolerances, ensuring consistent performance and reliability. This pack contains five discs, allowing maintenance personnel and safety officers to keep adequate stock on hand for immediate repairs, minimizing downtime in industrial environments.

Maintenance and Installation

Replacement of the safety valve disc is a standard procedure during regulator overhaul or immediately following an over-pressure event. It is crucial that the seating surface is clean and that the retaining cap is torqued to the manufacturer's specifications to prevent leaks or premature failure. These discs are compatible with specific ESAB and potentially legacy brand regulators (such as Victor or Purox, depending on the specific model lineage) that specify the R64 part number. Regular inspection of gas equipment for leaks and proper function is a cornerstone of industrial safety protocols.
