This 88 degree short radius bend is used to create a 90 degree change of direction in the soil stack. It is most commonly used on rainwater systems. The 88 degree angle of the bend is used to create a fall of 2 degrees within the system, promoting a self-cleansing flow. It is available in 50mm, 70mm, 100mm and 150mm size options. As Mech 416 pipes and fittings have no sockets, couplers are required to connect this bend to a pipe.
