HARRIS 425-200-540 Regulator Oxygen

Harris 425-200-540 oxygen single-stage regulator offers accurate pressure regulation for welding, cutting and brazing applications. The regulator ensures that the pressure of the gas is kept at a safe and consistent level for the specific application, allowing for precise control and optimal performance.

Working Mechanism:

• Attach the regulator to the oxygen cylinder and open the cylinder valve.
• Check the high-pressure gauge and adjust the first-stage regulator.
• Adjust the second stage regulator and check the low-pressure gauge.
• Use the oxygen and shut it off.

Features:

• It has a one-piece encapsulated seat design with an internal filter and a PTFE Teflon seat to resist corrosion, tearing and wearing.
• This regulator features a brass bonnet & body for improved flow control.
• It has a bronze adjusting screw for easy regulator adjustment.

Standards and Approvals:

• CGA-E-4

Frequently Asked Questions:

Q. How much inlet and outlet does this regulator have?

A. This regulator has a 540 CGA-inlet and a minimum 9/16 inch right-hand outlet along with a self-reseating HP safety valve (internal) for enhanced safety.

Q. How to clean Harris 425-200-540 oxygen regulator?

A.

• Turn off the oxygen supply and disconnect the regulator from the cylinder valve.
• Disassemble the regulator and clean the body and internal components with a clean, lint-free cloth, soft-bristled brush and compressed air.
• Wash the components with mild soap and water, rinse thoroughly and dry completely.
• Apply a small amount of lubricant to the O-ring or other sealing components.
• Reassemble the regulator and ensure all components are securely fastened.
• Test the regulator to ensure it's functioning properly.

Q. How to install this oxygen regulator?

A.

• Ensure the cylinder valve is closed.
• Remove the protective cap from the cylinder valve and check the valve outlet to ensure it is free from damage or debris.
• Match the regulator fitting to the cylinder valve. Harris 425-200-540 regulator has a CGA 540 connection, so make sure the cylinder valve has a matching CGA 540 connection.
• Attach the regulator to the cylinder valve by positioning the regulator over the cylinder valve and hand-tightening the regulator yoke screw or T-handle onto the cylinder valve. Use a wrench to tighten the regulator an additional 1/8 to 1/4 turn.
• Slowly open the cylinder valve by turning the handle counterclockwise. This allows the oxygen to flow into the regulator.
• Adjust the regulator by turning the regulator adjustment screw counterclockwise to increase the pressure or clockwise to decrease the pressure until the desired delivery pressure is reached.
• Attach the oxygen hose to the regulator outlet and ensure it is securely fastened.
• Turn the regulator adjustment screw counterclockwise to increase the delivery pressure slightly and listen for any hissing sounds that indicate a leak. Use a leak detection solution to check for any leaks around the fittings.
• Once you have confirmed that there are no leaks, you can use the oxygen for your intended application.
