You're right to be skeptical. The common understanding is that standard EMT compression fittings are generally not considered raintight.Here's a breakdown: Standard EMT Compression Fittings

These rely on the compression of a ring or sleeve to create a connection. While they can provide a secure mechanical connection and protect against mechanical damage, they don't typically have features designed to seal against water ingress.

Raintight/Watertight Fittings

Fittings intended for raintight or watertight applications have additional features like rubber gaskets or O-rings that create a seal when properly tightened.

EMT and Raintightness

While standard EMT compression fittings are not raintight, there are specific EMT fittings designed and listed as raintight or watertight. These fittings look similar to standard ones but have integrated sealing mechanisms. Look for markings on the fitting and packaging indicating raintight or watertight properties.

Therefore, it's not entirely accurate to say no EMT compression fitting can be raintight. Specialized raintight/watertight EMT compression fittings do exist. However, the standard versions are not.Important Considerations



Listing and Labeling

Always check the listing and labeling of the fitting. Look for markings like "Raintight" or "Wet Location" to confirm its suitability for outdoor use.

Installation

Even raintight fittings need to be installed correctly according to the manufacturer's instructions to achieve the desired seal.

Application

Consider the severity of the environment. For truly harsh conditions, you might want to explore other conduit types like rigid metal conduit (RMC) or PVC conduit with appropriate raintight fittings.

In summary, while standard EMT compression fittings are not raintight, there are raintight EMT compression fittings available. Make sure to use the correct fitting for your application and follow proper installation procedures. Flag for review
