Made by Oatey, FlowGuard Gold 1-Step all-weather fast set Yellow cement works for cold and hot water systems up to 200°F or 93°C. With a specially designed preventive formula, it protects pipes from corrosion. 

On the other hand, fast-set Orange cement comes in two variants, Oatey Heavy Duty Orange CPVC Cement and Oatey Medium Orange CPVC Cement. Professional plumbers have used hot and cold water systems for more than 100 years. 

Here are some key differences between Yellow and Orange CPVC cement: 

  • Features

Oatey has designed this FlowGuard Gold 1 step Yellow cement for all-weather protection for pipes round the year from corrosion. With a recommended application temperature of 0°F to 110°F, it sets fast and offers a low VOC. 

On the contrary, Oatey Orange CPVC cement with medium and heavy-duty variants is approved for Corzen CPVC piping systems. With medium and thick viscosity, this CPVC cement quickly fills gaps and provides more working time. 

Oatey recommends using this cement between 40°F and 110°F for a better result. 

  • Benefits 

Both Yellow and Orange CPVC cement offer some specific benefits. Let’s check them out. 

With Yellow CPVC cement, you will not have to apply any primer if your local code permits. While it is pretty easy to apply, you will get excellent gap-filling properties because of its medium body component size. 

Besides, it meets California South Coast Air Quality Management District requirements, a bonus for that locale. 

Similarly, Medium body Orange CPVC cement provides excellent gap filling properties and is pretty easy to use. But the thicker version can fill gaps for solid bonds.

Yellow CPVC cement is designed to use for cold and hot water systems. You can use this solvent for a temperature up to 200°F. 

Most importantly, you can use it with copper hot and cold potable water pipe witting up to 2 inches in diameter with an interference fit. 

In contrast, you can use Orange Medium CPVC cement with all types and classes of CPVC pipe having 6 inches diameter with an interference fit.

The number is 12 inches fittings in diameter. Besides, you can use this low VOC fast set cement for solvent welding. 

  • Set Time

Set time is essential for cement or solvent because it determines how much time you will require to finish the project. 

For Yellow CPVC cement, you will require 4 to 5 minutes at 30° F to 50° F to set. Similarly, it will take 2 to 3 minutes at 50° F to 70°F and 1 to 2 minutes at 70° F to 90° F. 

The set time is similar for both variants of Orange CPVC cement. So, there’s no difference between them in setting performance. 

  • Container Size

Container size is always important as it allows buyers to pick up the exact amount they need. It can be a determinant factor when choosing between two products.

For what’s it worth, both these products come in various similar size containers as the same company manufactures them. You will find 4 oz., 8 oz., 16 oz., 32 oz., and gallon containers for Yellow and Orange CPVC cement.
