PPH Elbow 45
A PPH 45° Elbow is a piping fitting made from Polypropylene Homopolymer (PPH) that is used to change the direction of fluid flow in a pipeline by 45 degrees. It ensures a smooth and gradual bend, reducing turbulence and pressure loss within the system.PPH Elbow 45° is made of Polypropylene Homopolymer (PPH). Metric 45° Degree Elbow Pressure Pipe Fittings are available in sizes PPH 45° elbows are pipe fittings used to form a 45 degree angle by joining two sections of pipe of the same diameter.
A PPH 45° elbow is a pipe fitting used to gently redirect flow at a 45° angle while maintaining efficient fluid movement. The joining method is recommended in our technical information and make sure you have the proper PPH Elbow 45° Solvent Cement and Cleaner to join the pipes and fittings together. These metrics can be found in our section on Accessories.Our pressure pipe range is made of Polypropylene Homopolymer (PPH) and has a working temperature of 30º to 180º F. It depends on the system pressure.
