Brass 90°Elbow double pex fitting

Brass PEX fitting is a type of plumbing fitting specifically designed for use with PEX (cross-linked polyethylene) piping. PEX is a flexible plastic piping material commonly used in residential and commercial plumbing systems, particularly for water supply lines and radiant heating systems. PEX fittings are essential for connecting PEX pipes to each other or to other types of plumbing materials.

Types: There are several types of PEX fittings, including:

Couplings: Used to connect two pieces of PEX pipe.
Elbows: Used to change the direction of the piping (e.g., 90-degree or 45-degree angles).
Tees: Used to create a branch in the piping system.
Adapters: Used to connect PEX to other types of piping materials, such as copper or PVC.
Caps and Plugs: Used to seal the end of a PEX pipe.
Connection Methods: PEX fittings can be connected to PEX pipes using various methods, including:

Applications: PEX fittings are commonly used in:
Residential plumbing systems (water supply lines)
Radiant heating systems
Hydronic heating systems

Advantages: PEX fittings and piping offer several advantages, including flexibility, resistance to scale and chlorine, lower shipping costs, and ease of installation. They are also less prone to freezing compared to traditional rigid piping materials.
