Adapters: Adapters are used to transition from PEX tubing to threaded pipes or fittings. Common adapters include PEX to female threaded, PEX to male threaded, and PEX to copper sweat adapters.

Cross: A Cross fitting is used to either combine or split the flow of the water. 


Elbows: These fittings are used to change the direction of the PEX piping at a 90-degree or 45-degree angle.


Straight Couplings: These fittings are used to join two PEX pipes together in a straight line.

Drop-Ear Elbows: These are a type of elbow fitting that has “ears” or tabs with screw holes for secure mounting to a wall or other surface.

Tees: A tee fitting is used to either combine or split the flow of the water. They have one input and two outputs (or vice versa) at 90-degree angles.
