PVDF Short Radius 45° Bend

The PVDF Short Radius 45° Bend is a precision-engineered pipe fitting used to change the direction of flow in piping systems by 45° degrees. This bend is designed to handle the corrosive media and high-purity applications where both chemical resistance and mechanical strength are critical. Its PVDF Short Radius 45° degree bend design allows for compact installations, making it suitable for tight spaces or systems requiring reduced flow path deviation.

A PVDF Short Radius 45° Bend is made from Polyvinylidene Fluoride (PVDF) that changes the direction of flow in a piping system by 45° degrees, with a shorter centerline radius compared to a long radius bend. The centerline radius (R) is approximately equal to the pipe diameter (1D). It creates a sharper turn than a long-radius bend to be used where space is limited.
