Astralpool FlexiMini Pure trim ring — anthracite - 77577-CL-144

Astralpool trim ring for liner pool return fitting nozzle 75778 — anthracite

This is the genuine Astralpool ABS trim ring (embellecedor) designed to fit flush over the face of the return fitting nozzle reference 75778 in liner pools. Its sole function is to frame the nozzle opening against the liner wall, covering the fixing flange and producing a clean, finished appearance at the waterline or below it. At 119 mm in diameter and 9 mm deep, it sits flat and tight without protruding into the water flow path.

What this trim ring does in the return fitting

The trim ring snaps or screws over the front face of nozzle 75778, concealing the mechanical fixings and the liner cut-out edge behind a smooth anthracite surround. It does not alter flow rate or jet direction — those are governed by the nozzle body itself. Its job is purely cosmetic and protective: keeping the liner edge seated correctly and preventing it from peeling away from the fitting over time.

Which return fitting models it fits

This trim ring is confirmed to fit Astralpool liner pool return fitting nozzle reference 75778 only. Do not attempt to fit it to other Astralpool nozzle references — the 119 mm outer diameter and the rear clip or thread geometry are specific to that nozzle body. If you are replacing a white or blue trim ring on an older installation, verify your nozzle reference before ordering this anthracite variant.

Signs it needs replacing

Discolouration, brittleness, or cracking of the ABS face are the most common failure modes, typically caused by prolonged UV exposure above the waterline or chemical attack from high chlorine concentrations. A trim ring that no longer sits flush allows the liner edge to lift at the fitting, which leads to water ingress behind the liner. Replace it at the first sign of cracking or if it no longer clips securely to the nozzle body.

How to install it

With the circulation pump off and the water level below the fitting, remove the old trim ring by pressing the retaining clips or unscrewing it from the nozzle face — no specialist tools required. Press the new anthracite ring firmly over the nozzle 75778 front face until all clips engage evenly around the circumference. Check that the liner is correctly trapped behind the flange before restarting the pump. The job takes under five minutes.
