G07-30 Split-Type Propane Cutting Nozzle | Chrome-Plated Shell + Detachable Brass Core | For Propane & LPG Cutting
Model: G07-30 Propane Cutting Nozzle | Sizes 1#, 2#, 3# | For G07-30 Injection-Type Cutting Torch
Product Overview
This G07-30 split-type propane cutting nozzle features a chrome-plated outer shell and a detachable brass inner core. With a total length of 55mm, it is available in sizes 1#, 2#, and 3#. Designed for propane / LPG fuel, it delivers a stable flame with high-temperature resistance and is compatible with the G07-30 injection-type cutting torch.
Key Advantages
Split Design, Lower Cost
The split design allows separate replacement of the inner brass core, significantly cutting maintenance costs compared to replacing the entire nozzle.
Corrosion-Resistant Chrome-Plated Shell
The chrome-plated outer shell provides excellent corrosion resistance, extending nozzle service life.
Concentrated Flame, Neat Cutting Surface
The concentrated flame produces a neat cutting surface with little slag, reducing post-cut cleanup.
Heat-Resistant & Anti-Burn-Out
Heat-resistant and anti-burn-out performance ensures reliable operation, with easy disassembly for maintenance.
Multiple Sizes Available
Different sizes (1#, 2#, 3#) fit various plate thicknesses, covering a cutting range of 3–30mm.

Usage Instructions
Installation: Select the appropriate size nozzle based on plate thickness. Screw the nozzle securely onto the G07-30 cutting torch. Ensure a tight fit to prevent gas leakage.
Pre-Use Check: Inspect the nozzle for damage or blockage. Verify that the inner brass core is properly seated and the outer shell is intact. Check all connections for leaks.
Flame Adjustment: Adjust the preheat oxygen and fuel gas valves to achieve a stable flame. Propane/LPG cutting requires different flame settings compared to acetylene — adjust according to actual conditions.
Cutting Operation: Preheat the workpiece to the ignition temperature, then press the cutting oxygen lever to begin cutting. Maintain a steady travel speed for a neat cut.
Safety Precautions:
Always check for gas leaks before use.
Wear appropriate eye protection during cutting.
Ensure adequate ventilation in the work area.
Keep flammable materials away from the cutting zone.
Allow the nozzle to cool before handling or replacing.
Maintenance: Clean the nozzle regularly to remove slag and spatter. Replace the inner brass core when worn or damaged. Store in a dry environment to prevent corrosion.
FAQ
Q: What is the difference between this nozzle and an acetylene nozzle?
A: This nozzle is specifically designed for propane and LPG. The internal geometry and gas passages are optimized for the different combustion characteristics of propane/LPG compared to acetylene.
Q: Can I replace only the inner core?
A: Yes. The split design allows the brass inner core to be replaced separately, significantly reducing maintenance costs.
Q: What is the total length of the nozzle?
A: The total length is 55mm.
Q: What torch is it compatible with?
A: It is designed for use with the G07-30 injection-type cutting torch.
Q: What cutting thickness does it cover?
A: The available sizes cover a cutting thickness range of 3–30mm. Select the appropriate size based on your plate thickness.
Q: How do I choose the right size?
A: Use 1# for 3–10mm, 2# for 10–20mm, and 3# for 20–30mm. Actual performance depends on gas pressure and operating conditions.
Q: What gases can be used?
A: Propane and LPG are both suitable. The nozzle is designed to deliver a stable flame with these fuels.
