Remember, HAND tight all the way 1st with brass fittings, only snug up with the wrench at the end…
Why… Because a 1-1/4″ wrench seen in this video has enough leverage that even the smallest person could strip brass fittings in seconds… Even with smaller wrenches brass is soft. So be careful with the inert gas line fittings as well…
If struggling when hand tightening ➡️ support the nipple stem, a little wiggle may help… The stem needs to be perpendicular to the valve opening…
You should never have to force them…
For machined brass fittings are meant to seat together preventing leaks without the aid of any Teflon tape or pipe dope…⬇️
If you find machined brass fittings with tape or dope on them it would be suspect aka SUS… ⬅️ ⬆️Troubleshoot, investigate and clear findings before use…
Also, always remember oils and greases in the presence of high pressure oxygen can be an explosion 💥 hazard…
So ➡️Store regulators away from oils and greases…
And ➡️ before cracking your cylinder to blow out any dust/shit from the valve before connecting regulators⬇️⬇️⬇️
Always inspect / CHECK for presents of oils or grease before hook up and use. ⬇️
Well doing that, check for damage also… ➡️ For damage on the threads most likely will equally, leaks.
Speaking of leaking ⬇️⬇️⬇️
Don’t forget that leak test solution should be designed for working with high pressure oxygen.
For the soapy water Makers ➡️ soap sometimes contains hydrocarbons which is a leading agent in petroleum products, ie oils…..
Let’s go with ➡️ use the right tools for the job…
Be safe out there…
And ⬇️⬇️⬇️
Happy Metal Processing….

Here’s a more detailed history of brass fittings used in oxy-acetylene cutting and welding systems, along with some references:
1. *Development of Oxy-Acetylene Welding*: The oxy-acetylene process was developed in the late 19th century. The first patents related to the process appeared in the 1900s, primarily attributed to French engineer Edmond Fouche. This method allowed for high-temperature flames capable of melting steel, paving the way for modern welding techniques. (Source: “The History of Oxy-Acetylene Welding” – The Fabricator)
2. *Introduction of Brass Fittings*: Brass fittings became widely accepted due to their favorable properties, including high corrosion resistance and non-sparking characteristics, which are crucial in handling flammable gases. The use of brass was common in various industrial applications by the early 20th century. (Source: “Welding Fittings: A Historical Overview” – Welding Journal)
3. *Standardization Efforts*: Organizations like the American National Standards Institute (ANSI) and the National Fire Protection Association (NFPA) set guidelines for the manufacturing and use of gas fittings, ensuring safety and compatibility across different systems. These standards began to take shape in the mid-20th century. (Source: ANSI/NFPA standards documentation)
4. *Design Evolution*: Over the years, the design of brass fittings has evolved to include a variety of shapes and sizes, accommodating the growing complexity of welding systems. The introduction of high-pressure fittings and safety features became more prevalent as welding applications expanded. (Source: “Welding and Cutting Equipment” – AWS)
5. *Modern Applications and Safety*: Today, brass fittings continue to be essential in oxy-acetylene systems. Advances in manufacturing technology have led to better quality control, enhancing the safety and reliability of these fittings. Regulatory bodies continuously update safety standards to reflect current best practices. (Source: “Safety in Welding and Cutting: Guidelines and Standards” – OSHA)
While specific references for some historical details may not be directly accessible in a single source, the information is compiled from a range of welding industry literature, historical engineering texts, and safety standard documentation. For in-depth research, consider looking into welding engineering textbooks, historical archives, and industry publications.
