The main drain flange 270 is a replacement mounting part from the manufacturer Astral intended for fastening the main drain in the pool floor. The flange ensures a watertight joint between the drain and the concrete or liner floor structure.
The original dimensions of the flange ensure precise compatibility with the other parts of the Astral 270 range, including the grate and the screw elements. The material, resistant to chlorinated water and pool chemicals, guarantees long-term tightness even in an aggressive environment.
Replacing the flange is necessary in the event of cracking, deformation or when renovating the pool floor. A correctly tightened flange is a prerequisite for the safe and reliable operation of the entire suction drain.
