AstralPool - Multiport Valve Top Fixing Ring Screws - SP-04-0308

AstralPool – multiport valve top fixing ring screws

These are genuine AstralPool replacement screws for the top fixing ring of AstralPool top-mount multiport (selector) valves. The fixing ring screws secure the valve’s upper cover assembly to the valve body, maintaining a watertight seal during filtration, backwashing, rinsing, and all other operating modes. Replacing worn or corroded screws is an essential part of keeping your multiport valve leak-free and structurally sound.

Function & importance

The top fixing ring screws clamp the valve cover firmly against the body, ensuring the internal gaskets and O-rings remain correctly compressed and sealed. Without intact fasteners, the cover assembly can work loose under system pressure, leading to leaks or loss of valve function. Regular inspection and timely replacement of these screws is recommended as part of end-of-season valve maintenance.

Compatibility

Designed for AstralPool top-mount multiport valves. Always cross-reference your valve model number against AstralPool’s official spare parts catalogue before ordering to confirm fitment, as screw dimensions may vary between valve generations and port sizes.

Installation

Before replacing the screws, stop the pump, isolate the system, and drain the valve completely. Remove the old fixing ring screws, inspect the cover O-ring and distributor gasket for wear, and replace if needed. Refit the cover ensuring the cover positioner aligns with the body locating hole, then tighten the new screws evenly to achieve a uniform, watertight seal. Do not overtighten.
