Different from application and use


Schedule 80PVC fittings should be selected to meet your requirements if PVC fittings are required to withstand great pressure and are used for industrial or chemical purposes. it can withstand greater pressure than schedule 40. 

However, if you have pipes in your home that need to be repaired or need to build irrigation projects, you can choose to Schedule 40PVC pipe fittings with less pressure. enough, you can save some cost. it is more appropriate if need to choose large diameter.


Different size and diameter


The PVC pipe fittings of Schedule 40 and Schedule 80 have the same outer diameter, but the pipe wall of Schedule 80 is thick. This means that the Schedule80 pipe will experience slightly less traffic, even though it may have the same pipe diameter as the same planned pipe.


In fact, sometimes you can put them together, but you need to pay attention to the low-pressure processing of the components that schedule Schedule40 to meet the stress requirements of your application. In this way, the strength of the pipe is only equivalent to the weakest part or joint, so even if Schedule40 is used in the higher pressure Schedule80, it may cause serious damage.


Different colors


Typically, the Schedule 40 pipeline is white, and Schedule 80 is usually gray, which makes it easier to distinguish. Some manufacturers will produce more colors for customers to choose. After all, many people choose it because of the different colors, especially the girls who love beauty. Therefore, PVC pipe fittings are still available in a variety of colors, but you must check the color and label at the time of purchase, just in case you buy the wrong one. White and gray can only represent most common plumbing fittings, just in case more color fittings appear.


Different water pressure ratings


Schedule40 and Schedule80 are widely used around the world, and of course they all have different application areas. Schedule40 has a thin wall, so it is best suited for low water pressure applications, suitable for home use, reducing costs. The Schedule 80 pipe is thick enough to withstand higher psi. This makes it an ideal choice for industrial and chemical applications.

Their colors will also be different. When you choose, you should choose according to your actual needs. You can't feel that it's good, you can't feel cheap and you can.
