There is sometimes confusion about what a class 125 fitting is – even in the industry. The truth may surprise you and save you some money in the end!
If you’ve ever seen a grade 125 PVC fitting, you’ll notice that it looks just like a standard grade 40 fitting. This is no coincidence. In fact, the 125-grade parts come from the exact same production line as the seemingly identical 40-grade parts. So what’s the difference? test.
Schedule 40 PVC fittings are specifically tested before leaving the factory to ensure they meet all the standards a Schedule 40 fitting should meet. This may include ASTM standards and others. Once they pass these tests, they receive a Schedule 40 stamp of approval.
Class 125 fittings do not perform this test. Instead, they are taken straight from the production line and sold in boxes. Although they are made using the same materials and craftsmanship, they are not technically 40 pieces.
When will Level 125 accessories be available? In general, for jobs where specs are not an issue but cost may be, we recommend class 125 fittings. While not guaranteed, you may get the same performance as using a similar schedule 40 PVC accessory. Class 125 accessories also cost significantly less than Schedule 40. They also tend to only be available in large diameter sizes. This helps offset the cost of accessories that are often very expensive.

In the world of electrical conduit, there are many materials and brands to choose from. Everyone has their own positive and negative side. In this article, we’ll look at some of the most widely used types and list the pros and cons of each catheter material.
Rigid Metal Conduit – Steel
Rigid steel conduit is available in two types: galvanized or non-galvanized. Steel is the heaviest of all conduit material types. It is typically used in commercial and industrial electrical applications where corrosion is not a major issue. The galvanizing process adds a protective coating of zinc to the steel conduit to help prevent corrosion. However, this is not a fail-safe system and corrosion is often an issue. This is especially true in wet or otherwise corrosive environments. Steel conduit is rigid but still prone to rust and degradation.
EMT – Electrical Metal Tube
EMT is another type of rigid metal conduit, but this type is thin-walled and does not have the same strength qualities as galvanized steel. Electrical metal pipes are usually made of steel or aluminum and are less expensive than standard conduit. Some electricians prefer to use an EMT because it can be bent to fit a specific raceway design. However, it also means that pipes are more fragile and more prone to rupture than other rigid pipes.
PVC conduit
The PVC conduit is very lightweight, so it is easy to drag and install. PVC is an excellent corrosion-resistant material and will not decompose in corrosive environments such as salt water or chemical exposure. The disadvantage of PVC is that it has no grounding capability and is a non-metallic conduit. To solve this problem, electricians use an extra ground conductor in all PVC conduit.
PVC coated conduit
PVC Coated Conduit offers the best in rigid steel and PVC conduit. PVC-coated conduits made by brands like Ocal and Robroy start with raw steel pipes. It is then galvanized and threaded. Next, it’s coated with polyurethane and then PVC. This way you get the benefits of steel (strength, weight, durability, grounding) and the benefits of PVC (rust and corrosion protection). PVC-coated conduit is designed to address the shortcomings of other types of conduit, providing the best option for a durable and corrosion-free electrical conduit piping system.
