0750-0055 - Victor Regulator Adjusting T-Screw Assembly

Genuine Victor 0750-0055 Adjusting Screw Assembly

The Victor 0750-0055 Adjusting Screw Assembly is a critical replacement component designed specifically for Victor's line of heavy-duty industrial gas regulators. When working with high-pressure oxy-fuel equipment, the precision and reliability of your pressure settings are paramount. This assembly serves as the primary interface for the operator to control delivery pressure, acting directly on the regulator's internal spring and diaphragm mechanism. Over time, threads can become worn, or the T-handle may suffer damage from impact in rugged workshop environments. Replacing this assembly restores the tactile feedback and fine control necessary for safe and efficient welding or cutting operations.

Manufactured to Victor's exacting OEM standards, this part ensures a perfect thread match for regulator bonnets found on the SR 450 and SR 460 series. Using non-OEM parts in gas regulation equipment can lead to thread galling, imprecise pressure control, or safety hazards. The 0750-0055 is built with high-quality materials, typically featuring a robust steel screw shaft and a durable cross-bar handle that provides excellent leverage, even when wearing heavy welding gloves. This design allows for smooth, granular adjustments of outlet pressure, which is essential for maintaining a stable flame during oxy-acetylene cutting or heating.

Maintenance of gas equipment is a key aspect of shop safety. A bent or stripped adjusting screw can make it difficult to back off pressure quickly in an emergency or may lead to creeping pressures if the internal spring is not engaged correctly. By installing a genuine Victor 0750-0055 assembly, you ensure that your regulator functions as intended by the manufacturer. This part is an economical solution to extend the service life of your premium Victor regulators, avoiding the significant cost of purchasing entirely new units when only the external control mechanism requires attention.
