PPH Tee

A PPH Tee is a pipe fitting made from Polypropylene Homopolymer (PPH) that is used to connect three pipes in a piping system, forming a T-shaped junction to allow the flow of fluid in two directions.PPH Tee is known as two in a straight line and one on the side at a 90-degree angle. Tees are used to divide a single line into two independent lines by connecting them at a 90-degree angle. PPH tee can also be used to join two lines together to form a single mainline. PPH Tees are a type of fitting that is incredibly adaptable and one of the most extensively used parts. The majority of PPH tee have slide socket ends; however, there are threaded versions as well.

Because they come with two sides in a straight line and one on the side at an angle of 90 degrees, our PPH tees are fitted with three ends. These tees are used to join two lines together to form a single mainline. Tees are incredibly adaptable fittings since they are one of the most extensively utilised parts in the industry.
