Why Replace Your Pressure Screw?

• Worn Threads – Difficulty achieving smooth pressure adjustment
• Damaged Screw – Bent or stripped threads affecting control
• Pressure Control Issues – Inability to maintain consistent pressure
• Preventive Maintenance – Replace before failure occurs
• Professional Standards – Maintain equipment reliability

Pressure Screw Function:

The regulator pressure screw is the core adjustment mechanism that controls nitrogen output pressure. Turning the screw adjusts the internal spring tension, which in turn regulates the nitrogen pressure delivered to the system. Precise pressure control is essential for accurate leak testing and safe system pressurisation.

Installation:

The pressure screw threads into the regulator body and connects to the internal pressure control mechanism. Ensure threads are clean and undamaged. Thread carefully to avoid cross-threading. Refer to the nitrogen regulator repairable parts breakdown diagram for proper assembly sequence and adjustment procedures.
