Tees (PEX x PEX x PEX)
Brass PEX Tees are used separate the water flow in two. A proper way to read PEX tees is: Side x Side x Top (Middle). For example, the following PEX fitting has 1/2" size in the middle (top) of the tee: 3/4" x 3/4" x 1/2" PEX. These PEX fittings are crimp style, manufactured to ASTM F1807 and are compatible with Crimp or Clamp connection systems.
