92Z07 - ESAB 92Z07 Safety Release Washer (Pack of 10)

Technical Overview of the ESAB 92Z07 Safety Release Washer

The ESAB 92Z07 Safety Release Washer is a critical replacement component designed for the maintenance and repair of industrial gas regulators, specifically those within the legacy Purox and Oxweld product lines now manufactured by ESAB. This washer is an integral part of the safety relief valve assembly found on the high-pressure side of many oxygen and inert gas regulators. The safety relief valve is a mandatory safety feature that vents excess pressure to the atmosphere in the event of a regulator seat failure or extreme over-pressurization, preventing the potential rupture of the regulator body or downstream equipment.

Constructed to precise dimensional tolerances, the 92Z07 washer ensures the correct seating and sealing of the safety release mechanism. In many regulator designs, this washer acts as a seal between the safety cap and the regulator body or works in conjunction with a rupture disc or spring-loaded relief valve. Over time, the material of the washer can degrade due to environmental exposure, compression set, or the thermal cycling associated with gas expansion. Failure to replace this washer during a regulator rebuild or safety inspection can lead to leaks at the safety valve, rendering the regulator unsafe for use.

This product is supplied as a bulk pack of 10 units, designated by the suffix "10-BAG" in some inventory systems. This packaging configuration is ideal for authorized repair centers, maintenance departments, and welding distributors who frequently service oxy-fuel and shielding gas equipment. Using genuine ESAB parts like the 92Z07 ensures compatibility with the specific thread pitches and seating surfaces of ESAB, Purox, and Oxweld regulators, maintaining the equipment's original safety ratings and performance specifications. Proper installation of this washer is essential for the regulator to pass leak testing and hold pressure according to CGA and manufacturer standards.

When servicing gas regulation equipment, it is standard procedure to replace all soft goods and sealing washers. The 92Z07 is a non-reusable component; once compressed in the assembly, it deforms to create a seal and cannot be reliably re-torqued. Technicians should verify the specific regulator model and parts breakdown to confirm the 92Z07 is the correct washer for the specific safety assembly being serviced.
