PPH Short Radius 45° Bend
A PPH Short Radius 45° Bend is a pipe fitting made from Polypropylene Homopolymer (PPH) that is used to change the direction of flow in a piping system by 45 degrees, with a short radius curvature (typically equal to the pipe diameter). The PPH Short Radius 45° Bend is a compact piping component designed to change the direction of flow by 45 degrees in restricted or tight piping layouts. Manufactured from Polypropylene Homopolymer (PPH), this fitting offers excellent chemical resistance, high mechanical strength, and long service life, even in aggressive industrial environments.
Used in a variety of fluid transport systems, this short-radius bend is ideal where space constraints prevent the use of long-radius alternatives. It is widely applied in chemical processing, water treatment, wastewater handling, and corrosive fluid systems.
