Stainless steel camlock fittings are primarily used in sanitary environments or food service because they don’t hold bacteria and prevent cross-contamination. They also work well in high-corrosive applications, as well. The goal is to choose SS 316 versions, which can be used for many years and still keep their high-polish shine.
These couplings have a variety of types, labeled as letters, such as A through F, as well as DC and DP. They also have a variety of sizes which range from ½” up to eight inches. While most of the adapters and couplers are interchangeable, the ½” and 8” versions have no international standards. Therefore, it’s essential to check to make sure they are going to fit in the application for which they’re needed.
The cam arms (handles) and finger rings use SS 304 for most applications. You can also find standard gaskets that are black. However, you can also find a variety of other gaskets that may work better when dealing with high pressures. Just make sure that the materials you choose for the gaskets are compatible with the powders or liquids you’re delivering.
Stainless steel is also ideal when working with water waste, salt water, or chemical, and can also be used for coolants and hydraulic oils.
Stainless steel couplings have to stay strong and durable regardless of what you’re moving inside. Therefore, you may be surprised that these couplings work well for high temperatures, as well as high pressures. They are also harder than other materials, such as brass, which means they break less under pressure.
If that weren’t enough, you can expect a longer life expectancy with stainless steel and won’t have to worry about corrosives damaging them over time. Plus, they don’t rust, which means they’re perfect for a variety of applications.
