What is the pressure rating for brass compression fittings?

Brass compression fittings are a type of plumbing fitting used to connect two pipes together. They are made from brass, which is an alloy of copper and zinc, and are designed to create a seal between two pipes without the need for soldering or welding. Compression fittings work by compressing a soft metal ring or ferrule onto the pipe when the fitting is tightened, creating a secure and tight seal. They are commonly used in plumbing and HVAC applications where a leak-free connection is essential. Some common examples of brass compression fittings include couplings, tees, elbows, and adapters.

The pressure rating for brass compression fittings can vary depending on the specific type, size, and manufacturer. In general, most brass compression fittings have a pressure rating between 150-300 psi (pounds per square inch). It's important to follow the manufacturer's specifications and guidelines to ensure the proper use and installation of these fittings.
