PPH Cross Tee
A PPH (Polypropylene Homopolymer) Cross Tee is a pipe fitting with four equal or reduced outlets arranged in a cross (plus “+”) shape, used to connect four pipes at right angles (90°) in a piping system.The PPH Cross Tee is a four-way pipe fitting designed to connect and branch flow in three directions from a single central inlet in a pipeline system. Made from Polypropylene Homopolymer (PPH), this fitting offers superior chemical resistance, rigidity, and thermal performance, making it ideal for demanding industrial and corrosive applications.
The cross tee allows for efficient distribution or merging of fluids and is commonly used in chemical processing, industrial fluid transport, water treatment, and aggressive media handling systems. Its robust and leak-proof construction ensures long-term reliability in high-performance piping networks.
